Mu’adh b. Jabal would pray along the prophet (ﷺ), then go and lead his people in prayer.

when the prophet (ﷺ) became seriously ill, we prayed behind him while he was sitting and Abu Bakr was calling “Allah is most great “ to cause the people to hear the TAKBIR. Then he (the narrators) narrated the rest of the tradition.

Abu Dawud said : The chain of this tradition is not continuous (muttasil)

The Messenger of Allah (ﷺ) entered upon Umm Haram. The people (in her house) brought some cooking oil dates to him. He said; Put it (dates) back in its container and return it (cooking oil) to its bag, because I am keeping fast. He then stood and led us in prayer two Rak’ahs of supererogatory prayer. Then Umm Sulaim and Umm Haram stood behind us (i.e., the men). Thabit (the narrator) said: I understand that Anas said; he (the prophet) made me stand on his right side.

“He took my head or the hair of my head and made me stand on his right side”.

'Abd Allah b. Rabah al-Ansari, whom the Ansar called faqih (juries), came to us from Medina, and reported us on the authority of Abu Qatadah al-Ansari, the horseman of the Messenger of Allah (ﷺ) saying: The Messenger of Allah (ﷺ) sent a military expedition consisting of the chief Companions. He then narrated the same story, saying Nothing awakened us except the rising sun. We stoop up in bewilderment, for our prayer. The Prophet (ﷺ) said: Wait a little, wait a little. When the sun rose high, the Messenger of Allah (ﷺ) said: Those who sued to observer the two rak'ahs of Fajr prayer (sunnah prayer before obligatory prayer) should observe them. Then those who used to observe and those who would not observe stood up and said prayer. Then the Messenger of Allah (ﷺ) commanded to call for prayer; the call for prayer was made accordingly. The Messenger of Allah (ﷺ) stood and led us in prayer. When he turned away (from the prayer) he said: We thank Allah for the fact that we were not engaged in any wordily affairs which detained us from our prayer. Instead our souls were in the hands of Allah. He released them whenever He wished. If any one of you gets morning prayer tomorrow at its proper time, he should offer a similar prayer as an atonement.

We proceeded with the Messenger of Allah (ﷺ) on the occasion of al-Hudaybiyyah. The Messenger of Allah (ﷺ) said: Who will keep watch for us? Bilal said: I (shall do). The overslept till the sun arose. The Prophet (ﷺ) awoke and said: Do as you used to do (i.e. offer prayer as usual). Then we did accordingly. He said: Anyone who oversleeps or forgets (prayer) should do similarly.

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

The Messenger of Allah (ﷺ) commanded us to build mosques in different localities (i.e. in the locality of each tribe separately) and that they should be kept clean and be perfumed.

If we left this door for women (it would have been better). Nafi' said: Ibn 'Umar did not enter (the door) until his death. The other except 'Abd al-Warith said: This was said by 'Umar (and not by Ibn 'Umar) and that is more correct.

I met ‘Uqbah b. Muslim and said to him: it has been reported to me that someone has narrated to you from the prophet (ﷺ) that when he entered the mosque, he would say: I seek refuge in Allah, the Magnificent, and in His noble face, and in his eternal domain, from the accursed Devil. He asked : is it so much only? I said: Yes. He said: when anyone says so. The devil says: he is protected from me all the day long.

Abu Qatadah reported the Messenger of Allah (May peace be upon him) as saying; when any one of you enters the mosque, he should pray two RAKAHS before sitting down.

then he may remain sitting (after praying two RAKAHS) or may go for his work.

I heard the Messenger of Allah (May peace be upon him) as saying; if anyone hears a man crying out in the mosque about something he has lost, he should say: May Allah not restore it to you, for the mosque were not built for this.

The Messenger of Allah (ﷺ) said: Spitting in the mosque is a sin and it is expiated by burying the spittle.

The Messenger of Allah (ﷺ) said: When a man stands with the intention of saying prayer, or if any of you says prayer, he should not spit before him, nor at his right side; but he should do so at his left side, if there is a place for it; or he should spit under his left foot and then rub it off.

The earth has been made for me purifying and as a mosque (place for prayer).

The Messenger of Allah (ﷺ) said: Command your children to pray when they become seven years old, and beat them for it (prayer) when they become ten years old; and arrange their beds (to sleep) separately.

Hisham ibn Sa'd reported: We entered upon Mu'adh ibn Abdullah ibn Khubayb al-Juhani. He said to his wife: When (at what age) should a boy pray? She replied: Some person of us reported: The Messenger of Allah (ﷺ) was asked about it; he said: When a boy distinguishes right hand from the left hand, then command him to pray.

when the Messenger of Allah (ﷺ) ordered a bell to be made so that it might be struck to gather the people for prayer, a man carrying a bell in his hand appeared to me while I was asleep, and I said; servant of ‘abd Allah, will you sell the bell? He asked; what will you do with it? I replied; we shall use it to call the people to prayer. He said; should I not suggest you something better than that. I replied: certainly. Then he told me to say: Allah is most great, Allah is most great, Allah is most great, Allah is most great. I testify that there is no god but Allah, I testify that Muhammad is the Messenger of Allah. Come to pray, come to pray; come to salvation; come to salvation. Allah is most great, Allah is most great. I testify that there is no god but Allah. He then moved backward a few steps and said: when you utter the IQAMAH, you should say: Allah is most great, Allah is most great. I testify that there is no god but Allah, I testify that Muhammad is the Messenger of Allah. Come to prayer, come to salvation. The time for prayer has come, the time for prayer has come: Allah is most great, Allah is most great. There is no god but Allah. When the morning came, I came to the Messenger of Allah (May peace be upon him) and informed him of what I had seen in the dream. He said: it is a genuine vision, and he then should use it to call people to prayer, for he has a louder voice than you have. So I got up along with Bilal and began to teach it to him and he used it in making the call to prayer. ‘Umar b. al-khattab (Allah be pleased with him) heard it while he was in his house and came out trailing his cloak and said: Messenger of Allah. By him who has sent you with the truth, I have also seen the kind of thing as has been shown to him. The Messenger of Allah (May peace be upon him) said: To Allah be the praise.Abu Dawud said; Al-Zuhri narrated this tradition in a similar way from Sa’id b. al-Musayyib on the authority of ‘Abd Allah b. Zaid. In this version Ibn Ishaq narrated from al-Zuhri: Allah is most great. Allah is most great, Allah is most great, Allah is most great. Ma;mar and yunus narrated from al-Zuhri; Allah is most great, Allah is most great. They did not report it twice again.
