Allah's Apostle said, "One prayer in my Mosque is better than one thousand prayers in any other mosque excepting Al-Masjid-AI-Haram."

The Messenger of Allah (saws) came and saw that the doors of the houses of his Companions were facing the mosque. He said: Turn the direction of the houses from the mosque. The Prophet (saws) then entered (the houses or the mosque), and the people did take any step in this regard hoping that some concession might be revealed. He the Prophet) again came upon them and said: Turn the direction of these (doors) from the mosque I do not make the mosque lawful for a menstruating woman and for a person who is sexually defiled.

Abu Dawud said: Aflat b. Khalifah is also called Fulait al-'Amiri.

I heard my father saying, "Never did Allah's Apostle assume Ihram except at the Mosque, that is, at the Mosque of Dhul-Hulaifa.

Yahya related to me from Malik from Zayd ibn Rabah and Ubaydullah ibn Abi Abdullah Salman al-Agharr from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, said, "A prayer in this mosque of mine is better than a thousand prayers in any other mosque, except the Masjid al-Haram (in Makka)."

The first Jumua prayer which was offered after a Jumua prayer offered at the mosque of Allah's Apostle took place in the mosque of the tribe of `Abdul Qais at Jawathi in Bahrain.

The Prophet used to go to the Mosque of Quba (sometimes) walking and sometimes riding. Added Nafi` (in another narration), "He then would offer two rak`at (in the Mosque of Quba)."

The first Friday (i.e. Jumua) prayer offered after the Friday Prayer offered at the Mosque of Allah's Apostle was offered at the mosque of `Abdul Qais situated at Jawathi, that is a village at Al Bahrain .

(who fought in twelve Ghazawat in the company of the Prophet). I heard four things from the Prophet and they won my admiration. He said; -1. "No lady should travel on a journey of two days except with her husband or a Dhi-Mahram; -2. "No fasting is permissible on the two days of Id-ul-Fitr and `Id-ul-Adha; -3. "No prayer (may be offered) after the morning compulsory prayer until the sun rises; and no prayer after the `Asr prayer till the sun sets; -4. "One should travel only for visiting three Masjid (Mosques): Masjid-al-Haram (Mecca), Masjid-al- Aqsa (Jerusalem), and this (my) Mosque (at Medina).

She heard the Messenger of Allah (saws) say: If anyone puts on ihram for hajj or umrah from the Aqsa mosque to the sacred mosque , his former and latter sins will be forgiven, or he will be guaranteed Paradise. The narrator Abdullah doubted which of these words he said.

Abu Dawud said: May Allah have mercy on Waki'. He put on ihram from Jerusalem (Aqsa mosque), that is, to Mecca.

The Prophet sent some horsemen to Najd and they brought a man called Thumama bin Uthal from Bani Hanifa. They fastened him to one of the pillars of the mosque. The Prophet came and ordered them to release him. He went to a (garden of) date-palms near the mosque, took a bath and entered the mosque again and said, "None has the right to be worshipped but Allah and Muhammad is His Apostle" (i.e. he embraced Islam).

The Messenger of Allah (saws) prohibited buying and selling in the mosque, announcing aloud about a lost thing, the recitation of a poem in it, and prohibited sitting in a circle (in the mosque) on Friday before the prayer.

The Prophet said, "When it is a Friday, the angels stand at the gate of the mosque and keep on writing the names of the persons coming to the mosque in succession according to their arrivals. The example of the one who enters the mosque in the earliest hour is that of one offering a camel (in sacrifice). The one coming next is like one offering a cow and then a ram and then a chicken and then an egg respectively. When the Imam comes out (for Jumua prayer) they (i.e. angels) fold their papers and listen to the Khutba."

That the Messenger of Allah (saws) said: "When you see someone selling or buying in the Masjid then say: 'May Allah not profit your business.' And when you see someone announcing about something lost then say: 'May Allah not return it to you.'"

The Hadith of Abu Hurairah is Hasan Gharib. This is acted upon according to some of the people of knowledge. They dislike selling and buying in the Masjid. This is the view of Ahmad and Ishaq. Some of the people of knowledge permitted selling and buying in the Masjid.

I said, "O Allah's Apostle! Which mosque was built first?" He replied, "Al-Masjid-ul-Haram." I asked, "Which (was built) next?" He replied, "Al-Masjid-ul-Aqs-a (i.e. Jerusalem)." I asked, "What was the period in between them?" He replied, "Forty (years)." He then added, "Wherever the time for the prayer comes upon you, perform the prayer, for all the earth is a place of worshipping for you."

The sunnah for one who is observing i'tikaf (in a mosque) is not to visit a patient, or to attend a funeral, or touch or embrace one's wife, or go out for anything but necessary purposes. There is no i'tikaf without fasting, and there is no i'tikaf except in a congregational mosque.

The Prophet entered the Mosque, and I too went there after tying the camel at the pavement of the Mosque. I said (to the Prophet ), "This is your camel." He came out and started examining the camel and said, "Both the camel and its price are for you."

The Prophet said, "The prayer offered in congregation is twenty five times more superior (in reward) to the prayer offered alone in one's house or in a business center, because if one performs ablution and does it perfectly, and then proceeds to the mosque with the sole intention of praying, then for each step which he takes towards the mosque, Allah upgrades him a degree in reward and (forgives) crosses out one sin till he enters the mosque. When he enters the mosque he is considered in prayer as long as he is waiting for the prayer and the angels keep on asking for Allah's forgiveness for him and they keep on saying: 'O Allah! Be Merciful to him, O Allah! Forgive him, as long as he keeps on sitting at his praying place and does not pass wind. (See Hadith No. 620).

I said, "O Allah's Apostle! Which mosque was first built on the surface of the earth?" He said, "Al- Masjid-ul-,Haram (in Mecca)." I said, "Which was built next?" He replied "The mosque of Al-Aqsa ( in Jerusalem) ." I said, "What was the period of construction between the two?" He said, "Forty years." He added, "Wherever (you may be, and) the prayer time becomes due, perform the prayer there, for the best thing is to do so (i.e. to offer the prayers in time).

Jabir reported that Allah's Messenger (may peace be upon him) commanded a person who had been distributing arrows freely in the mosque that he should not move about in the mosque but by catching hold of their iron-heads. Ibn Rumh narrated this with a slight variation of wording.

Yahya related to me from Malik that he had asked Ibn Shihab whether someone doing itikaf could go into a house to relieve himself, and he said, "Yes, there is no harm in that."

Malik said, "The situation that we are all agreed upon here is that there is no disapproval of anyone doing itikaf in a mosque where jumua is held. The only reason I see for disapproving of doing itikaf in a mosque where jumua is not held is that the man doing itikaf would have to leave the mosque where he was doing itikaf in order to go to jumua, or else not go there at all. If, however, he is doing itikaf in a mosque where jumua is not held, and he does not have to go to jumua in any other mosque, then I see no harm in him doing itikaf there, because Allah, the Blessed and Exalted, says, 'While you are doing itikaf in mosques,' and refers to all mosques in general, without specifying any particular kind."

Malik continued, "Accordingly, it is permissiblefor a man to do itikaf in a mosque where jumua is not held if he does not have to leave it to go to a mosque where jumua is held."

Malik said, "A person doing itikaf should spend the night only in the mosque where he is doing itikaf, except if his tent is in one of the courtyards of the mosque. I have never heard that someone doing itikaf can put up a shelter anywhere except in the mosque itself or in one of the courtyards of the mosque.

Part of what shows that he must spend the night in the mosque is the saying of A'isha, 'When the Messenger of Allah, may Allah bless him and grant him peace, was doing itikaf, he would only go into the house to relieve himself.' Nor should he do itikaf on the roof of the mosque or in the minaret."

Malik said, "The person who is going to do itikaf should enter the place where he wishes to do itikaf before the sun sets on the night when he wishes to begin his itikaf, so that he is ready to begin the itikaf at the beginning of the night when he is going to start his itikaf. A person doing itikaf should be occupied with his itikaf, and not turn his attention to other things which might occupy him, such as trading or whatever. There is no harm, however, if some one doing itikaf tells some one to do something for him regarding his estate, or the affairs of his family, or tells someone to sell some property of his, or something else that does not occupy him directly. There is no harm in him arranging for someone else to do that for him if it is a simple matter."

Malik said, "I have never heard any of the people of knowledge mentioning any modification as far as how to do itikaf is concerned. Itikaf is an act of ibada like the prayer, fasting, the hajj, and such like acts, whether they are obligatory or voluntary. Anyone who begins doing any of these acts should do them according to what has come down in the sunna. He should not start doing anything in them that the muslims have not done, whether it is a modification that he imposes on others, or one that he begins doing himself. The Messenger of Allah, may Allah bless him and grant him peace, practised itikaf, and the muslims know what the sunna of itikaf is."

Malik said, "Itikaf and jiwar are the same, and Itikaf is the same for a village-dweller as it is for a nomad."

AbuThumamah al-Hannat said that Ka'b ibn Ujrah met him while he was going to the mosque; one of the two (companions) met his companion (on his way to the mosque) And he met crossing the fingers of my both hands. He prohibited me to do so, and said: The Messenger of Allah (saws) has said: If any of you performs ablution, and performs his ablution perfectly, and then goes out intending for the mosque, he should not cross the fingers of his hand because he is already in prayer.

He (Abu Hurayrah) said: I heard my friend AbulQasim (saws) say: On the Day of Resurrection Allah will raise martyrs from the mosque of al-Ashshar, who will be the only ones to rise with the martyrs of Badr.

Abu Dawud said: This mosque is near the river.

(The people of) Bani Salama intended to shift near the mosque (of the Prophet) but Allah's Apostle disliked to see Medina vacated and said, "O the people of Bani Salama! Don't you think that you will be rewarded for your footsteps which you take towards the mosque?" So, they stayed at their old places.
