I saw Messenger of Allah (PBUH) lying down on his back in the mosque, placing one leg on the other.

[Al-Bukhari and Muslim].

The Messenger of Allah (PBUH) said, "It is not proper to use the mosque for urinating or easing oneself. They are merely built for the remembrance of Allah and the recitation of the Qur'an", or as he stated.

[Muslim].

During the days of the battle of the harra[*] neither the call to prayer nor the declaration that the time for prayer had come was made for three days at the Prophet's Mosque. Sa'id b. al-Musayyib did not leave the mosque, and the only means by which he knew the time for prayer was a whinnying he heard coming from the Prophet's grave. *When the people of Medina rebelled against the Umayyad Caliph Yazid he sent an army under Muslim b. 'Uqba al-Murri towards the end of 63 A.H. The Medina troops were defeated in a battle known by the name given above. Darimi transmitted it.

The Messenger of Allah (PBUH) said, "Convey glad tidings to those who walk to the mosque in the darkness. For they will be given full light on the Day of Resurrection."

[At-Tirmidhi and Abu Dawud].

Abu Huraira reported God’s Messenger as saying, “If anyone goes out in the morning or in the evening to the mosque, God will prepare for him his food in paradise as often as he goes out in the morning or in the evening.” (Bukhari and Muslim.)

Zaid b. Thabit reported God s Messenger as saying, “A man’s prayer in his house is more excellent than his prayer in this mosque of mine, except for the prescribed prayer." Abu Dawud and Tirmidhi transmitted it.

Anas told that when God's messenger entered the mosque no one but Abu Bakr and `Umar raised his head. They would smile to him and he would smile to them. Tirmidhi transmitted it, saying this is a gharib tradition.

Abu Sa'id al-Khudri reported God’s Messenger as saying, “When you see a man frequenting the mosque, testify that he has faith, for God says, ‘God’s mosques are visited only by those who believe in God and the last day.”* * Al-Qur'an; 9:18 Tirmidhi, Ibn Majah and Darimi transmitted it.

Allah's Messenger said: "Whoever says, when he hears the Mu'adh-dhin: (Wa Ana Ashadu An La Ilaha Illallah, Wahdahu La Sharika Lahu, Wa Anna Muhammadan Abduhu Wa Rasuluhu, Radittu Billahi Rabban Wa Bil-Islam Dinan, Wa Bi Muhammadin Rasulan) 'I too testify that none has the right to be worshiped but Allah, Alone without partners, and that Muhammad is His slave and Messenger, I am pleased with Allah as my Lord, with Islam as my religion and Muhammad as a Messenger.' - Allah will pardon his sins for him."

“When the Prophet (saws) would see the wind he would say: ‘O Allah, indeed, I ask You for its good, the good of what is in it, and the good of what it has been sent with. And I seek refuge in You from its evil, the evil of what is in it, and the evil of what it has been sent with (Allāhumma innī as’aluka min khairihā wa khairi mā fīhā, wa khairi mā ursilat bihī, wa a`ūdhu bika min sharrihā wa sharri mā fīhā, wa sharri mā ursilat bih).’”

Whenever the wind blew strongly, The Prophet (PBUH) would say: "Allahumma inni as'aluka khairaha, wa khaira ma fiha, wa khaira ma ursilat bihi. Wa a'udhu bika min sharriha, wa sharri ma fiha, wa sharri ma ursilat bihi. (O Allah, I beg of You its good and the good of that which it contains and the good of the purpose for which it has been sent; and I seek Your Refuge from its evil and the evil of that which it contains and the evil of the purpose for which it has been sent)."

[Muslim].

A man announced (the loss of his camel) in the mosque, uttering these words: "Has any one seen my red camel?" Upon this the Messenger of Allah (PBUH) said, "May it not be restored to you! The mosques are built for what they are meant to be (i.e., prayer, remembrance of Allah, acquiring knowledge, etc.)."

[Muslim].

Yahya related to me from Malik that he had heard that Said ibn al-Musayyab said, "It is said that no-one except a hypocrite leaves the mosque after the call to prayer, except for someone who intends to return."

the Prophet said: "The Salat in Masjid Quba is like Umrah."

I saw the principal Companions of Messenger of Allah (PBUH) rushing to the pillars (of the mosque) to perform two Rak'ah prayers behind them before the Maghrib prayer.

[Al-Bukhari].

O Messenger of Allah (ﷺ), I vowed during the jahiliyyah to observe i’tikaf for one night in al-Masjid al-Haram. He said to him: “Fulfil your vow.”

Ibn ‘Umar said that when ‘Umar consulted the Prophet about a vow he had made in the pre-Islamic period to spend a night in devotion in the sacred mosque, he said, “Fulfill your vow.” (Bukhari and Muslim.)

Messenger of Allah (PBUH) used to teach us the Istikharah (seeking guidance from Allah) in all matters as he would teach us a Surah of the Qur'an. He used to say: "When one of you contemplates entering upon an enterprise, let him perform two Rak'ah of optional prayer other than Fard prayers and then supplicate: "Allahumma inni astakhiruka bi 'ilmika, wa astaqdiruka bi qudratika, wa as-'aluka min fadlikal-'azim. Fainnaka taqdiru wa la aqdiru, wa ta'lamu wa la a'lamu, wa Anta 'allamul- ghuyub. Allahumma in kunta ta'lamu anna hadhal-'amra (and name what you want to do) khairun li fi dini wa ma'ashi wa 'aqibati amri, (or he said) 'ajili amri ajilihi, faqdurhu li wa yassirhu li, thumma barik li fihi. Wa in kunta ta'lamu anna hadhal 'amra (and name what you want to do) sharrun li fi dini wa ma'ashi wa 'aqibati amri, (or he said) wa 'ajili amri wa ajilihi, fasrifhu 'anni, wasrifni 'anhu, waqdur liyal- khaira haithu kana, thumma ardini bihi." (O Allah, I consult You through Your Knowledge, and I seek strength through Your Power, and ask of Your Great Bounty; for You are Capable whereas I am not and, You know and I do not, and You are the Knower of hidden things. O Allah, if You know that this matter (and name it) is good for me in respect of my Deen, my livelihood and the consequences of my affairs, (or he said), the sooner or the later of my affairs then ordain it for me, make it easy for me, and bless it for me. But if You know this matter (and name it) to be bad for my Deen, my livelihood or the consequences of my affairs, (or he said) the sooner or the later of my affairs then turn it away from me, and turn me away from it, and grant me power to do good whatever it may be, and cause me to be contented with it). And let the supplicant specify the object."

[Al-Bukhari]

While the Messenger of Allah (saws) was leading his Companions in prayer, he took off his sandals and laid them on his left side; so when the people saw this, they removed their sandals. When the Messenger of Allah (saws) finished his prayer, he asked: What made you remove your sandals? The replied: We saw you remove your sandals, so we removed our sandals.

The Messenger of Allah (saws) then said: Gabriel came to me and informed me that there was filth in them. When any of you comes to the mosque, he should see; if he finds filth on his sandals, he should wipe it off and pray in them.

Harithah ibn Mudarrib said that he came to Abdullah ibn Mas'ud and said (to him): There is no enmity between me and any of the Arabs. I passed a mosque of Banu Hanifah. They (the people) believed in Musaylimah. Abdullah (ibn Mas'ud) sent for them. They were brought, and he asked them to repent, except Ibn an-Nawwahah. He said to him: I heard the Messenger of Allah (saws) say: Were it not that you were not a messenger, I would behead you. But today you are not a messenger. He then ordered Qarazah ibn Ka'b (to kill him). He beheaded him in the market. Anyone who wants to see Ibn an-Nawwahah slain in the market (he may see him).

He who eats garlic or onion must keep away from us. Or he said: must keep away from our mosque or must sit in his house. A dish containing green vegetables was brought to him, and noticing that it had an odour he asked (about it). He was told that it contained some vegetables. He then said: Bring it near, to one of his companion who was with him. When he saw it, he abominated eating it, and said: eat for I hold intimate converse with one with whom you do not. Ahmad b. Salih said: Ibn Wahb explained the word badr as meaning dish.

The Messenger of Allah (saws) entered the mosque (and saw that) a rope tied between two pillars. He asked: What is this rope (for) ? The people told him: This is (for) Hamnah b. Jahsh who prays (here). When she is tired, she reclines on it. The Messenger of Allah (saws) said: She should pray as much as she has strength. When she is tired, she should sit down.

This version of Ziyad has: He said: What is this ? The people told him: This is for Zainab who prays. When she becomes lazy, or is tired, she holds it. He said: Undo it. One of you should pray in good spirits. When he is lazy or tired, he should sit down.

The mosque (of the Prophet) during his lifetime was built with bricks, its roof with branches of the palm-tree, and its pillars with palm-wood, as Mujahid said: Abu Bakr did not add anything to it. But 'Umar added to it; he built as it was built during the lifetime of the Messenger of Allah (saws) with bricks and branches, and he changed its pillars. Mujahid said: Its pillars were made of wood. 'Uthman changed it altogether with increasing addition. He built its walls with decorated stone and lime. And he built the pillars with decorated stone and its roof with teak. Mujahid said: Its roof was made of teak.

Abu Dawud said: Al-Qassah means lime used as mortar.

When the Messenger of Allah (saws) was observing I'tikaf (in the mosque), I would come to him to visit him. I had a talk with him and then stood up. I then returned and he (the Prophet) also stood up to accompany me (to my house). Her dwelling place was in the house of Usamah b. Zaid. Two men from the Ansar (helpers) passed (by him at the moment). When they saw the Prophet (saws), they walked quickly. The Prophet (saws) said: Be at ease, she is Safiyyah daughter of Huyayy. They said: Be glory to Allah, Messenger of Allah! He said: Satan runs in man like blood. I feared he might inspire something in your mind, or he said: evil (the narrator doubted).

The Mosque (of the Prophet) was built in the land of Banu al-Najjar which contained crops, palm trees and graves of the disbelievers. The Messenger of Allah (saws) said: Sell it to me for some price. They (Banu al-Najjar) replied: We do not want (any price). The palm-trees were cut off, and the crops removed and the graves of the disbelievers dug opened. He then narrated the rest of the tradition. But this version has the word "forgive" in the verse, instead of the word "help". Musa said: 'Abd al-Warith also narrated this tradition in a like manner. The version of 'Abd al-Warith has the word "dung-hill" (instead of crop), and he asserted that he narrated this tradition to Hammad.

“When the Messenger of Allah (saw) prayed Tahajjud at night, he would say: “Allahumma lakal-hamd, Anta nurus-samawati wal-ard wa man fihinna. Wa lakal-hamd, Anta qayyamus-samawati wal-ard wa man fihinna. Wa lakal-hamd, Anta malikus- samawati wal-ard wa man fihinna. Wa lakal-hamd, Antal-haqq, wa wa`duka haqq, wa liqa’uka haqq, wa qawluka haqq, wal-jannatu haqq, wan-naru haqq, was-sa`atu haqq, wan-nabiyyuna haqq, wa Muhammadun haqq. Allahumma laka aslamtu, wa bika amantu, wa `alaika tawakkaltu wa ilaika anabtu, wa bika khasamtu, wa ilaika hakamtu, faghfirli ma qaddamtu wa ma akhkhartu, wa ma asrartu wa ma a`lantu. Antal-muqaddimu wa Antal-muakhkhiru. La ilaha illa anta wa la ilaha ghairuka, wa la hawla wa la quwwata illa bika (O Allah, to you is praise, You are the Light of the heavens and the earth, and everyone therein. To You is praise, You are the Sustainer of the heavens and the earth, and everyone therein. To You is praise, You are the Sovereign of the heavens and the earth, and everyone therein. To You is praise, You are the Truth; Your promise is true, the meeting with You is true, Your saying is true, Paradise is true, the Fire is true, the Hour is true, the Prophets are true, and Muhammad (saws) is true. O Allah, to You have I submitted, in You I believe, in You have I put my trust, to You I turn in repentance, by Your help I argue, to You I refer my case, so forgive me for my past and future sins, what I have done in secret and what I have done openly. You are the One Who brings forward and puts back. None has the right to be worshipped but You, and there is none who has the right to be worshipped other than You. And there is no power and no strength except with You.”
Another chain that Ibn `Abbas narrated: “When the Messenger of Allah (saws) stood during the night for Tahajjud,” and he mentioned something similar.

"Allah's Messenger taught me some phrases to say during Al-Witr (Allahummahdini fiman hadait, wa a'fini fiman afait, wa tawallani fiman tawallait, wa barik Li fima atait, wa qini sharra ma qadait, fa Innaka taqdi wa la yuqda Alaik, wa innahu la yadhillu man walait, tabarakta Rabbana wa ta'alait.) 'O Allah guide me among those You have guided, pardon me among those You have pardoned, befriend me among those You have befriended, bless me in what You have granted, and save me from the evil that You decreed. Indeed You decree, and none can pass decree, and none can pass decree upon You, indeed he is not humiliated whom You have befriended, blessed are You our Lord and Exalted.'"

The Messenger of Allah (saws) said: “Whoever wakes up in the night and says, ‘None has the right to be worshiped but Allah, alone, without partner, to Him belongs the Dominion, and to Him is the praise, and He has power over all things. And Glory is to Allah, and all the praise is to Allah, and ‘None has the right to be worshiped but Allah, and Allah is the greatest, and there is no might nor power except by Allah (Lā ilāha illallāh, waḥdahu lā sharīka lahu, lahul-mulku wa lahul-ḥamdu, wa huwa `alā kulli shai'in qadīr. Wa subḥān Allah, walḥamdulillāh, wa lā ilāha illallāh, wa Allāhu akbar, wa lā ḥawla wa lā quwwata illā billāh.)’ – then he said: ‘O my Lord, forgive me (Rabbighfirlī)’ – or he said – ‘then he supplicates, he shall be responded to. So he makes a firm determination, then performs Wudu', then he performs Salat, his Salat shall be accepted.”

that the Prophet (SAW) would recite: "Furuhun Wa Raihanun Wa Jannatu Na'im (56:89)"

about his grandfather Jarhad, he said: "The Prophet (SAW) passed by Jarhad in the Masjid and his thigh was exposed, so he said: 'Indeed the thigh is 'Awrah.'"

The Messenger of Allah (PBUH) said, "When anyone of you enters the mosque, he should perform two Rak'ah (of voluntary prayer) before sitting."

[Al-Bukhari and Muslim].

Whenever the Messenger of Allah (PBUH) returned from a journey, he would proceed straight to the mosque and perform two Rak'ah of (optional) prayer.

[Al-Bukhari and Muslim].

He said that when God’s messenger put his foot in the stirrup and his she-camel stood up with him on its back, he raised his voice in the talbiya from the mosque of Dhul Hulaifa. Bukhari and Muslim.

Ka'b b. Malik said that the Prophet always came back from a journey by day in the forenoon, and when he arrived he went first to the mosque, and having prayed two rak'as in it he sat down in it. (Bukhari and Muslim.)

Sulama daughter of al-Hurr reported God’s Messenger as saying, "One of the signs of the last hour will be that people in a mosque will refuse to act as imam and will not find an imam to lead them in prayer.” Ahmad, Abu Dawud, and Ibn Majah transmitted it.

God’s Messenger sent us in a detachment and said, “When you see a mosque or hear a mu’adhdhin (The one who makes the call to prayer) do not kill anyone.” Tirmidhi and Abu Dawud transmitted it.

Yahya related to me from Malik from Hisham ibn Urwa that his father never brought food or drink, nor even a remedy which he ate or drank but that he said, "Praise be to Allah who has guided us and fed us and given us to drink and blessed us. Allah is greater. O Allah! We have found Your blessing with every evil, give us every good in the morning and evening. We ask You for its completion and its gratitude. There is no good except Your good. There is no god other than You, the God of the salihun and the Lord of the Worlds. Praise be to Allah. There is no god but Allah. What Allah wills. There is no power except in Allah. O Allah! Bless us in what You have provided us with and protect us from the punishment of the Fire!"

Al-hamdu lillahi-lladhi hadana wa at amana wa saqana wa naamana. Allahu akbar. Allahumma'l fatna nimatik bi-kulli sharr. Fa asbahna minha wa amsayna bi-kulli khayr. Nasaluka tamamaha wa shukraha. La khayr illa khayruk. Wa la ilaha ghayruk. Ilaha'-saliheen wa rabba'l-alameen. Al-hamdu lillah. Wa la ilaha illa'llah. Ma sha'Allah. Wa la quwwata illa billah. Allahumma barik lana fima razaqtana. Waqina adhaba'n-nar.

“O Allah, indeed, I seek refuge in You from the trial of the Fire, and the punishment of the Fire, and the punishment of the grave, and the trial of the grave, and from the evil of the trial of the grave, and from the evil of the trials of riches, and from the evils of the trials of poverty, and from the evil of the trial of the false Masih. O Allah, wash my sins with water of ice and hail, and cleanse my heart of sins, as You cleansed a white garment of filth, and distance me and my sins as You distanced between the east and the west. O Allah, indeed, I seek refuge in You from laziness, senility, sin and debt. (Allāhumma innī a`ūdhu bika min fitnatin-nār, wa `adhābin-nār, wa `adhābil-qabr, wa fitnatil-qabr, wa min sharri fitnatil-ghinā, wa min sharri fitnatil-faqr, wa min sharri fitnatil- masīḥid-dajjāl.

"While we were in the masjid on Friday and the Messenger of Allah (SAW) was addressing the people, a man stood up and said: 'O Messenger of Allah, the routes have been cut off, our wealth has been destroyed and prices have gone up. Pray to Allah (SWT) to give us rain.' So the Messenger of Allah (SAW) raised his hands in level with his face and said: 'O Allah, give us rain.' By Allah (SWT), the Messenger of Allah (SAW) had not come down from the minbar before it started to pour with rain, and it rained from that day until the following Friday. Then a man stood up- I do not know if he was the same man who had asked the Messenger of Allah (SAW) to pray for rain for us or not- and said: 'O Messenger of Allah, the routes have been cut off, and our wealth has been destroyed because there is too much water. Pray to Allah (SWT ) to stop the rain for us.' The Messenger of Allah (SAW) said: 'O Allah, around us and not on us, rather on the mountains and places where trees grow.' By Allah, hardly had the Messenger of Allah (SAW) spoken these words than the clouds split apart (and vanished) until we could not see anything of them.'"

"By Allah, I adjure a man who heard the Messenger of Allah, on the day when the mountain shook with him, and he kicked it with his foot and said: 'Be still, for there is no one upon you but a Prophet or a Siddiq or two martyrs,' and I was with him." Some men responded and affirmed that. Then he said: "By Allah, I adjure a man who witnessed the Messenger of Allah, on the day of Bai'at Al-Ridwan, say: 'This is the Hand of Allah and this is the hand of 'Uthman.'" Some men responded and affirmed that. He said: "By Allah, I adjure a man who heard the Messenger of Allah say, on the day of the army of Al-'Usrah (i.e. Tabuk): 'Who will spend and it will be accepted?' And I equipped half of the army from my own wealth." Some men responded and affirmed that. Then he said: "By Allah, I adjure a man who heard the Messenger of Allah say: 'Who will add to this Masjid in return for a house in Paradise,' and I bought it with my own wealth." Some men responded and affirmed that. Then he said: "By Allah, I adjure a man who witness Rumah being sold, and I bought it from my own wealth and allowed wayfarers to use it." Some men responded and affirmed that.

Yahya related to me from Malik from Rabia ibn Abi Abd ar-Rahman that if Abdullah ibn Umar arrived at the mosque and the people had already prayed, he would begin with the obligatory prayer and not pray anything before it.

Allah's Messenger (S) said: "When one of you performs Wudu and does so well, then he leaves intending to go to the Masjid, then let him not intertwine his fingers, for indeed he is in Salat."

that the Messenger of Allah (SAW) passed through the Masjid one day, and a group of women were sitting, so he motioned his hand with the Salam - 'Abdul-Hamid (one of the narrators) gestured with his hand.

The Prophet (PBUH) would not perform any Salat (in the mosque) after the Friday prayer till he had returned to his house. He would then perform two Rak'ah there.

[Muslim].

I heard the Messenger of Allah (ﷺ) say: `Whoever builds a mosque for the sake of Allah, may He be glorified and exalted. Allah will build something like it for him in Paradise.”

‘A'isha said, “During his private devotional exercises God’s messenger would put his head near me when he was in the mosque, and I would comb it; and he entered the house only to relieve himself.” (Bukhari and Muslim.)

Malik said that ‘Umar built a courtyard called al-Butaiha’ in the neighbourhood of the mosque and said, “If anyone wants to make a noise, or recite poetry, or raise his voice, he must go out to this courtyard.” He transmitted it in al-Muwatta'.

‘Uthman b. ‘Affan reported God’s Messenger as saying, “If the adhan is called when anyone is in the mosque and he goes out for any other reason than some necessary purpose, not intending to return, he is a hypocrite.” Ibn Majah transmitted it.

Jabir reported God’s Messenger as saying, “When one of you performs the prayer in his mosque he should leave a portion of his prayer for his house, for God blesses his house because of his prayer.” Muslim transmitted it.

Ibn `Abbas reported the Prophet as saying, "0 God, strengthen Islam with Abu Jahl b. Hisham, or `Umar b. al-Khattab." In the morning `Umar went to the Prophet and accepted Islam; then prayed openly in the mosque. Ahmad and Tirmidhi transmitted it.
