The Prophet saw expectoration in the direction of the Qibla of the mosque while he was leading the prayer, and scratched it off. After finishing the prayer, he said, "Whenever any of you is in prayer he should know that Allah is in front of him. So none should spit in front of him in the prayer."

Allah's Apostle said, "A person is considered in prayer as long as he is waiting for the prayer in the mosque as long as he does not do Hadath." A non-Arab man asked, "O Abu Huraira! What is Hadath?" I replied, "It is the passing of wind (from the anus) (that is one of the types of Hadath).

I heard Jabir bin `Abdullah saying, "The Prophet said, 'Whoever eats (from) this plant (he meant garlic) should keep away from our mosque." I said, "What does he mean by that?" He replied, "I think he means only raw garlic."

I asked `Amra about taking a bath on Fridays. She replied, " Aisha said, 'The people used to work (for their livelihood) and whenever they went for the Jumua prayer, they used to go to the mosque in the same shape as they had been in work. So they were asked to take a bath on Friday.' "

`Umar bin Al-Khattab said, "O Allah's Apostle! I vowed in the Pre-Islamic period to perform I`tikaf in Al-Masjid-al-Haram for one night." The Prophet said, "Fulfill your vow." So, he performed I`tikaf for one night.

Ubayy b. Ka'b reported that he was sitting in a mosque that a person entered it and he observed prayer, and made recitation, the rest of the hadith is the same.

A man said, "O Allah's Apostle! If a man finds another man with his wife, (committing adultery) should the husband kill him?" Later on I saw them (the man and his wife) doing Li`an in the mosque (taking oaths, one accusing, and the other denying adultery).

Ibn Umar reported that the Messenger of Allah (may peace be upon him) saw sputum sticking to the Qibla wall of the mosque, the rest of the hadith is the same.

When the Prophet arrived Medina he dismounted at `Awali-i-Medina amongst a tribe called Banu `Amr bin `Auf. He stayed there For fourteen nights. Then he sent for Bani An-Najjar and they came armed with their swords. As if I am looking (just now) as the Prophet was sitting over his Rahila (Mount) with Abu Bakr riding behind him and all Banu An-Najjar around him till he dismounted at the courtyard of Abu Aiyub's house. The Prophet loved to pray wherever the time for the prayer was due even at sheep-folds. Later on he ordered that a mosque should be built and sent for some people of Banu-An-Najjar and said, "O Banu An-Najjar! Suggest to me the price of this (walled) piece of land of yours." They replied, "No! By Allah! We do not demand its price except from Allah." Anas added: There were graves of pagans in it and some of it was unleveled and there were some date-palm trees in it. The Prophet ordered that the graves of the pagans be dug out and the unleveled land be level led and the date-palm trees be cut down . (So all that was done). They aligned these cut date-palm trees towards the Qibla of the mosque (as a wall) and they also built two stone side-walls (of the mosque). His companions brought the stones while reciting some poetic verses. The Prophet was with them and he kept on saying, "There is no goodness except that of the Hereafter, O Allah! So please forgive the Ansars and the emigrants. "

Ibn `Umar used to spend the night at Dhi-Tuwa in between the two Thaniyas and then he would enter Mecca through the Thaniya which is at the higher region of Mecca, and whenever he came to Mecca for Hajj or `Umra, he never made his she camel kneel down except near the gate of the Masjid (Sacred Mosque) and then he would enter (it) and go to the Black (stone) Corner and start from there circumambulating the Ka`ba seven times: hastening in the first three rounds (Ramal) and walking in the last four. On finishing, he would offer two rak`at prayer and set out to perform Tawaf between Safa and Marwa before returning to his dwelling place. On returning (to Medina) from Hajj or `Umra, he used to make his camel kneel down at Al-Batha which is at Dhul-Hulaifa, the place where the Prophet used to make his camel kneel down.

I asked Abu Sa`id, and he was a friend of mine, (about the Night of Qadr) and he said, "We practiced I`tikaf (seclusion in the mosque) in the middle third of the month of Ramadan with the Prophet . In the morning of the 20th of Ramadan, the Prophet came and addressed us and said, 'I was informed of (the date of the Night of Qadr) but I was caused to forget it; so search for it in the odd nights of the last ten nights of the month of Ramadan. (In the dream) I saw myself prostrating in mud and water (as a sign). So, whoever was in I`tikaf with me should return to it with me (for another 10-day's period)', and we returned. At that time there was no sign of clouds in the sky but suddenly a cloud came and it rained till rainwater started leaking through the roof of the mosque which was made of date-palm leaf stalks. Then the prayer was established and I saw Allah's Apostle prostrating in mud and water and I saw the traces of mud on his forehead."

Safiya, the wife of the Prophet told me that she went to Allah's Apostle to visit him in the mosque while he was in I`tikaf in the last ten days of Ramadan. She had a talk with him for a while, then she got up in order to return home. The Prophet accompanied her. When they reached the gate of the mosque, opposite the door of Um-Salama, two Ansari men were passing by and they greeted Allah's Apostle . He told them: Do not run away! And said, "She is (my wife) Safiya bint Huyai." Both of them said, "Subhan Allah, (How dare we think of any evil) O Allah's Apostle!" And they felt it. The Prophet said (to them), "Satan reaches everywhere in the human body as blood reaches in it, (everywhere in one's body). I was afraid lest Satan might insert an evil thought in your minds."

While I was praying, the Prophet passed by and called me, but I did not go to him till I had finished my prayer. When I went to him, he said, "What prevented you from coming?" I said, "I was praying." He said, "Didn't Allah say" "O you who believes Give your response to Allah (by obeying Him) and to His Apostle." (8.24) Then he added, "Shall I tell you the most superior Sura in the Qur'an before I go out of the mosque?" When the Prophet intended to go out (of the Mosque), I reminded him and he said, "That is: "Al hamdu-li l-lahi Rabbil-`alamin (Surat-al-fatiha)' which is the seven oft repeated verses (Al-Mathani) and the Grand Qur'an which has been given to me."

The wife of the Prophet that she went to Allah's Apostle while he was in I`tikaf (staying in the mosque) during the last ten nights of the month of Ramadan. She spoke to him for an hour (a while) at night and then she got up to return home. The Prophet got up to accompany her, and when they reached the gate of the mosque opposite the dwelling place of Um Salama, the wife of the Prophet, two Ansari men passed by, and greeting Allah's Apostle , they quickly went ahead. Allah's Apostle said to them, "Do not be in a hurry She is Safiya, the daughter of Huyai." They said, "Subhan Allah! O Allah's Apostle (how dare we suspect you)." That was a great thing for both of them. The Prophet then said, "Satan runs in the body of Adam's son (i.e. man) as his blood circulates in it, and I was afraid that he (Satan) might insert an evil thought in your hearts."

A Bedouin stood up and started making water in the mosque. The people caught him but the Prophet ordered them to leave him and to pour a bucket or a tumbler of water over the place where he had passed the urine. The Prophet then said, "You have been sent to make things easy and not to make them difficult."

Allah's Apostle saw some expectoration on the wall of the mosque; he took gravel and scraped it off and said, "If anyone of you wanted to spit, he should neither spit in front of him nor on his right but could spit either on his left or under his left foot."

Once I saw Allah's Apostle at the door of my house while some Ethiopians were playing in the mosque (displaying their skill with spears). Allah's Apostle was screening me with his Rida' so as to enable me to see their display. (`Urwa said that `Aisha said, "I saw the Prophet and the Ethiopians were playing with their spears.")

I sold a camel to the Prophet on one of the journeys. When we reached Medina, he ordered me to go to the Mosque and offer two rak`at. Then he weighed for me (the price of the camel in gold) and gave an extra amount over it. A part of it remained with me till it was taken by the army of Sham on the day of Harra."

While some people were offering Fajr prayer in the Quba' mosque, some-one came and said, "Allah has revealed to the Prophet Qur'anic instructions that you should face the Ka`ba (while praying) so you too, should face it." Those people then turned towards the Ka`ba.

While the Prophet was praying, he saw sputum (on the wall) of the mosque, in the direction of the Qibla, and so he scraped it off with his hand, and the sign of disgust (was apparent from his face) and then said, "Whenever anyone of you is in prayer, he should not spit in front of him (in prayer) because Allah is in front of him."

Allah's Apostle saw some expectoration on the wall of the mosque; he took gravel and scraped it off and said, "If anyone of you wanted to spit he should neither spit in front of him nor on his right but he could spit either on his left or under his left foot."

Had Allah's Apostle known what the women were doing, he would have forbidden them from going to the mosque as the women of Bani Israel had been forbidden. Yahya bin Sa`id (a sub-narrator) asked `Amra (another sub-narrator), "Were the women of Bani Israel forbidden?" She replied "Yes."

Allah's Apostle used to go (for Hajj) via Ash-Shajara way and return via Muarras way; and no doubt, whenever Allah's Apostle went to Mecca, he used to offer the prayer in the Mosque of Ash-Shajara; and on his return, he used to offer the prayer at Dhul-Hulaifa in the middle of the valley, and pass the night there till morning.

`Umar said "O Allah's Apostle! I vowed to perform I`tikaf for one night in Al-Masjid-al-Haram, during the Pre-Islamic Period of ignorance (before embracing Islam). "The Prophet said, "Fulfill your vow." Ibn `Umar said to the lady, "Pray on her behalf." Ibn `Abbas said the same.

This hadith has been narrated, on the authority, of Abu Huraira (with this change of words)." A person whose heart is attached to the mosque when he goes out of it till he returns to it."

One of the wives of `Umar (bin Al-Khattab) used to offer the Fajr and the `Isha' prayer in congregation in the Mosque. She was asked why she had come out for the prayer as she knew that `Umar disliked it, and he has great ghaira (self-respect). She replied, "What prevents him from stopping me from this act?" The other replied, "The statement of Allah's Apostle : 'Do not stop Allah's women-slaves from going to Allah's Mosques' prevents him."

Allah's Apostle once delayed the `Isha' prayer and that was during the days when Islam still had not spread. The Prophet did not come out till `Umar informed him that the women and children had slept. Then he came out and said to the people of the mosque: "None amongst the dwellers of the earth has been waiting for it (`Isha prayer) except you."

"When the Mu'adh-dhin pronounced the Adhan, some of the companions of the Prophet would proceed to the pillars of the mosque (for the prayer) till the Prophet arrived and in this way they used to pray two rak`at before the Maghrib prayer. There used to be a little time between the Adhan and the Iqama." Shu`ba said, "There used to be a very short interval between the two (Adhan and Iqama).

Safiya bint (daughter of) Huyai came to the Prophet (in the mosque), and when she returned (home), the Prophet accompanied her. It happened that two men from the Ansar passed by them and the Prophet called them saying, "She is Safiya!" those two men said, "Subhan Allah!" The Prophet said, "Satan circulates in the human body as blood does."

Ibn Umar (Allah be pleased with them) reported that Allah's Messenger (may peace be upon him) came to the mosque at Quba' riding and on foot, and he observed two rak'ahs of (Nafl prayer) in it.

'Abbad b. Tamim reported from his uncle that he saw Allah's Messenger (may peace be upon him) lying in the mosque and placing his one foot upon the other.

The Prophet was on a journey and recited in one of the first two rak`at of the `Isha' prayer "Wa t-teeni wa z-zaitun." (95)
