When the Messenger of Allah (ﷺ) recited the verse Not of those with whom Thou art angry, nor of those who go astray, he would say Amin so loudly that those near him in the first row would hear it.

Abu Hurairah reported the prophet (ﷺ) as saying; when the imam recites “ not of those with whom thou art angry, nor of those who go astray” (surah al-fatihah,verse 7) say Amin, for if one’s words (utterance of amin) synchronise with those of the angles, he will be forgiven his past sins.

Abu Hurairah reported the Messenger of Allah (May peace be upon him) as saying; When the Imam says Amin, say Amin, for if anyone’s utterance of Amin synchronnises with that of the angles, he will be forgiven his past sins.

Ibn shihab (al Zuhrl) said; The Messenger of Allah (May peace be upon him) used to say Amin (At the end of the Fatihah)

Messenger of Allah, do not say Amin before me.

AbuMisbah al-Muqra'i said: We used to sit in the company of AbuZuhayr an-Numayri. He was a companion of the Prophet (ﷺ), and he used to narrate good traditions. Once a man from among us made a supplication. He said: End it with the utterance of Amin, for Amin is like a seal on the book.

AbuZuhayr said: I shall tell you about that. We went out with the Messenger of Allah (ﷺ) one night and came upon a man who made supplication with persistence. The Prophet (ﷺ) waited to hear him. The Prophet (ﷺ) said: He will have done something which guarantees (Paradise for him) if he puts a seal to it. One of the people asked: What should he use as a seal? He replied: Amin, for if he ends it with Amin, he will do something which guarantees (Paradise for him).

Then the man who questioned the Prophet (ﷺ) came to the man who was supplicating, and said to him: So-and-so, end it with Amin and receive the good news. These are the words of Mahmud.

Abu Dawud said: Al-Muqra'i is a clan of Himyar.

Abu Hurairah reported the Messenger of Allah (ﷺ) as saying; Glorifying Allah applies to men and clapping applies only to women.

The Messenger of Allah (ﷺ) went to Banu ‘Amr b. ‘Awf to effect reconciliation between them . in the meantime the time of prayer came and the Mu’adhdhin came to Abu Bakr and asked : Will you lead the people in prayer? I pronounce the Iqamah. He said ; Yes. So Abiu Bakr led the prayer , and the Messenger of Allah (ﷺ) came back while the people were praying. He penetrated through the rows and stood in the first row. The people clapped but Abu Bakr did not pay any attention to it during prayer. When the people clapped increasingly, he paid attention. He saw the Messenger of Allah (ﷺ). The Messenger of Allah (ﷺ) made a sign to him (saying); Stay at your place. Abu BAkr raised his hands and praised Allah for the commandment the Messenger of Allah (ﷺ) had given him (to lead the people in prayer). Abu Bakr then stepped back and stood in the row. The Messenger of Allah (ﷺ) stepped forward and led the prayer. When he finished the prayer, he said; Abu Bakr, what prevented you staying (at your place) when I already commented you to do so? Abu Bakr said ; it was not befitting for the son of Abu Quhafah (Abu Bakr) to lead the prayer in the presence of the Messenger of Allah (ﷺ). The Messenger of Allah (ﷺ) said; What is the matter that I saw you clapping frequently during prayer? If anything happens to someone during prayer, he should say “Glory be to Allah,” for when he glorifies Allah. He pays attention to him. Clapping applies only to women.

Abu Dawud said: This is operative in the obligatory prayer.
