They heard the Prophet say on his pulpit: "People should desist from failing to attend the congregations, otherwise Allah will seal their hearts, and they will be among the negligent."

"When one of their womenfolk menstruated, the Jews would not eat or drink with them, or mix with them in their houses. They (the Companions) asked the Prophet of Allah (PBUH) about that, and Allah, the Mighty and Sublime, revealed the Ayah: They ask you concerning menstruation. Say: "That is an Adha (a harmful thing).[2] So the Messenger of Allah (PBUH) commanded them to eat and drink with them (menstruating women) and to mix them in their houses, and to do everything with them except intercourse. The Jews said: 'The Messenger of Allah (PBUH) does not leave anything of our affairs except he goes against it.' Usaid bin Hudair and 'Abbad bin Bishr went and told the Messenger of Allah (PBUH) and they said: 'Should we have intercourse with them when they are menstruating?' The expression of the Messenger of Allah (PBUH) changed greatly until we thought he was angry with them, and they left. Then the Messenger of Allah (PBUH) received a gift of milk, so he sent someone to bring them back and he gave them some to drink, so we knew that he was not angry with them." [1] Al-Baqarah 2:222 [2] Al-Baqarah 2:222

Prayer said by a man in congregation is twenty five degrees more excellent than prayer said by him alone in his house or in the market. This is because when any of you performs ablution and does it perfectly, and goes out to the mosque having no intention except praying, and nothing moves him except prayer, then at every step which he takes his rank is elevated by one degree on account of this (walking), and one sin is remitted from him for this (walking), till he enters the mosque. When he enters the mosque, he will be reckoned as praying as long as he will be detained by the prayer. The angels keep on invoking blessing on any of you so long as he remains seated in the place he prayer, saying: O Allah, forgive him; O Allah, have mercy on him; O Allah, accept his repentance so long as he does not harm anyone, or breaks his ablution.

I was present with the Prophet at his pilgrimage and prayed the Morning Prayer along with him in the mosque of al-Khaif. When he finished his prayer and turned away there were two men at the back of the people who had not prayed along with him. He said, “Bring them to me,” and they were brought trembling with fear. He asked what had prevented them from praying along with him, and they replied, “Messenger of God, we had already prayed in our lodging.” He said, “Don’t do so. When you pray in your lodging and then come to a mosque where there is a congregation, you must pray along with them, and it will be a supererogatory prayer for you. Tirmidhi, Abu Dawud and Nasa’i transmitted it.

"The Messenger of Allah said: 'The prayer of a man in congregation is higher than his prayer on his own by twenty-four or twenty-five levels."

The Prophet used to say: "Whoever performs prayer in congregation at the mosque for forty nights, never missing the first Rak'ah of the 'Isha' prayer, Allah will thereby decree for him salvation from the Fire."

“I heard my father say: ‘I heard ‘Umar bin Khattab say: “The Messenger of Allah (saw) said: ‘Eat together and do not eat separately, for the blessing is in being together.’”

the Messenger of Allah said: "Whoever prays Fajr in congregation, then sits remembering Allah until the sun has risen, then he prays two Rak'ah, then for him is the reward like that of a Hajj and Umrah." He said: "The Messenger of Allah said: 'Complete, complete, complete.'"

Sa'id ibn al-Musayyab said: An Ansari was breathing his last. He said: I narrate to you a tradition, and I narrate it with the intention of getting a reward from Allah.

I heard the Messenger of Allah (saws) say: If any one of you performs ablution and performs it very well, and goes out for prayer, he does not take his right step but Allah records a good work (or blessing) for him, and he does not take his left step but Allah remits one sin from him. Any one of you may reside near the mosque or far from it; if he comes to the mosque and prays in congregation, he will be forgiven (by Allah).

If he comes to the mosque while the people had prayed in part, and the prayer remained in part, and he prays in congregation the part he joined, and completed the part he had missed, he will enjoy similarly (i.e. he will be forgiven). If he comes to the mosque when the people had finished prayer, he will enjoy the same.

AbuImran said: We went out on an expedition from Medina with the intention of (attacking) Constantinople. AbdurRahman ibn Khalid ibn al-Walid was the leader of the company. The Romans were just keeping their backs to the walls of the city. A man (suddenly) attacked the enemy.

Thereupon the people said: Stop! Stop! There is no god but Allah. He is putting himself into danger.

AbuAyyub said: This verse was revealed about us, the group of the Ansar (the Helpers). When Allah helped His Prophet (saws) and gave Islam dominance, we said (i.e. thought): Come on! Let us stay in our property and improve it.

Thereupon Allah, the Exalted, revealed, "And spend of your substance in the cause of Allah, and make not your hands contribute to (your destruction)". To put oneself into danger means that we stay in our property and commit ourselves to its improvement, and abandon fighting (i.e. jihad).

AbuImran said: AbuAyyub continued to strive in the cause of Allah until he (died and) was buried in Constantinople.

The Messenger of Allah (saws) forbade us to eat horse-flesh, the flesh of mules and of asses. The narrator Haywah added: Every beast of prey with a fang.

Abu Dawud said: This view is held by Malik.

Abu Dawud said: There is no harm in (eating) horse-flesh and this tradition is not practised.

Abu Dawud said: This tradition has been abrogated. A body of Companions of the Prophet (saws) had eaten horse-flesh. OF them are: Ibn al-Zubair, Fudalah bin 'Ubaid, Anas bin Malik, Asma' daughter of Abu Bakr, Suwaid bin Ghaflah, 'Alqamah; the Quraish used to slaughter them (horses) during the time of the Messenger of Allah (saws).

Mu`awiyah b. Abi Sufiyan stood among us and said: Beware! The Apostle of Allah (saws) stood among us and said: Beware! The people of the Book before were split up into seventy two sects, and this community will be split into seventy three: seventy two of them will go to Hell and one of them will go to Paradise, and it is the majority group.

Ibn Yahya and `Amr added in their version : “ There will appear among my community people who will be dominated by desires like rabies which penetrates its patient”, `Amr’s version has: “penetrates its patient. There remains no vein and no joint but it penetrates it.”
