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.
