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.

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

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

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).

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 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."

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 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).

(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.

The Messenger of Allah (may peace be upon him) used to observe two rak'ahs of Sunnah (prayer) when he heard the Adhin and shortened them.

We prayed along with the Prophet facing Jerusalem for sixteen or seventeen months. Then Allah ordered him to turn his face towards the Qibla (in Mecca):-- "And from whence-so-ever you start forth (for prayers) turn your face in the direction of (the Sacred Mosque of Mecca) Al-Masjid-ul Haram.." (2.149)

(freed slave of) Ziyad: I heard Abu Sa`id Al-khudri narrating four things from the Prophet and I appreciated them very much. He said, conveying the words of the Prophet. (1) "A woman should not go on a two day journey except with her husband or a Dhi-Mahram. (2) No fasting is permissible on two days: `Id-ul-Fitr and `Id-ul-Adha. (3) No prayer after two prayers, i.e. after the Fajr prayer till the sunrises and after the `Asr prayer till the sun sets. (4) Do not prepare yourself for a journey except to three Mosques, i.e. Al-Masjid-AI-Haram, the Mosque of Aqsa (Jerusalem) and my Mosque."

Allah's Apostle ordered for a horse race; the trained horses were to run from a place called Al-Hafya' to Thaniyat Al-Wada` and the horses which were not trained were to run from Al-Thaniya to the Masjid (mosque of) Bani Zuraiq. The sub narrator added: Ibn `Umar was one of those who took part in the race.

Abu Sa`id who participated in twelve Ghazawat with the Prophet said, "I heard four things from Allah's Apostle (or I narrate them from the Prophet ) which won my admiration and appreciation. They are: -1. "No lady should travel without her husband or without a Dhu-Mahram for a two-days' journey. -2. No fasting is permissible on two days of `Id-ul-Fitr, and `Id-al-Adha. -3. No prayer (may be offered) after two prayers: after the `Asr prayer till the sun set and after the morning prayer till the sun rises. -4. Not to travel (for visiting) except for three mosques: Masjid-al-Haram (in Mecca), my Mosque (in Medina), and Masjid-al-Aqsa (in Jerusalem).

Prior to the construction of the mosque, the Prophet offered the prayers at sheep-folds.

The Prophet led us in prayer and then went up to the pulpit and beckoned with both hands towards the Qibla of the mosque and then said, "When I started leading you in prayer, I saw the display of Paradise and Hell on the wall of the mosque (facing the Qibla). I never saw good and bad as I have seen today." He repeated the last statement thrice.

The Prophet said, "Spitting in the mosque is a sin and its expiation is to bury it."

The distance between the wall of the mosque and the pulpit was hardly enough for a sheep to pass through.

The Prophet used to go to the Quba' mosque, sometimes walking, sometimes riding.

I heard `Uthman bin `Affan saying, when people argued too much about his intention to reconstruct the mosque of Allah's Apostle, "You have talked too much. I heard the Prophet saying, 'Whoever built a mosque, (Bukair thought that `Asim, another sub-narrator, added, "Intending Allah's Pleasure"), Allah would build for him a similar place in Paradise.' "

The Prophet saw some sputum on the wall facing the Qibla of the mosque and became furious with the people of the mosque and said, "During the prayer, Allah is in front of everyone of you and so he should not spit (or said, 'He should not expectorate')." Then he got down and scratched the sputum with his hand. Ibn `Umar said (after narrating), "If anyone of you has to spit during the prayer, he should spit to his left."

The Prophet said, "If your women ask permission to go to the mosque at night, allow them."

The distance between the pulpit and the wall of the mosque on the side of the Qibla was just sufficient for a sheep to pass through.
