Narrated Sahl bin Sad:
The news about the differences amongst the people of Bani 'Amr bin 'Auf at Quba reached Allah's Apostle and so he went to them along with some of his companions
to affect a reconciliation. Allah's Apostle was delayed there and the time for the prayer became due. Bilal came to Abu Bakr! and said, "O Abu Bakr! Allah's Apostle is detained (there) and the time for the prayer is due. Will you lead the people in prayer?" Abu Bakr replied, "Yes, if you wish." So Bilal pronounced the Iqama and Abu Bakr went forward and the people said Takbir. In the meantime, Allah's Apostle came piercing through the
srows till he stood in the (first) row and the people started clapping. Abu Bakr, would never look hither and thither during the prayer but when the people clapped much he looked back and saw Allah's Apostle. The Prophet beckoned him to carry on. Abu Bakr raised both his hands, praised Allah and retreated till he stood in the row and Allah's Apostle went forward and led the people in the prayer. When he had finished the prayer, he addressed the people and said, "O people! Why did you start clapping when something happened to you in the prayer? Clapping is for women. Whenever one is confronted with something unusual in the prayer one should say, 'Sub Han Allah'." Then the Prophet looked towards Abu Bakr and asked, "What prevented you from leading the prayer when I beckoned you to carry on?" Abu Bakr replied, "It does not befit the son of Al Quhafa to lead the prayer in the presence of Allah's Apostle
Bukhari :: Book 9 :: Volume 89 :: Hadith 300
Narrated Sahl bin Sa'd As-Saidi:
There was some quarrel (sighting) among Bani 'Amr, and when this news reached the Prophet, he offered the Zuhr prayer and
went to establish peace among them. In the meantime the time of 'Asr prayer was due, Bilal pronounced the Adhan and then the Iqama for the prayer and requested Abu Bakr (to lead the prayer) and Abu Bakr went forward. The Prophet arrived while Abu Bakr was still praying. He entered the rows of praying people till he stood behind Abu Bakr in the (first) row. The people started clapping, and it was the habit of Abu Bakr that whenever he stood for prayer, he never glanced side-ways till he had finished it, but when Abu Bakr observed that the clapping was not coming to an end, he looked and saw the Prophet standing behind him.
The Prophet beckoned him to carry on by waving his hand. Abu Bakr stood there for a while, thanking Allah for the saying of the Prophet and then he retreated, taking his steps backwards. When the Prophet saw that, he went ahead and led the people in prayer. When he finished the prayer, he said, "O Abu Bakr! What prevented you from carrying on with the prayer after I beckoned you to do so?" Abu Bakr replied, "It does not befit the son of Abi Quhafa to lead the Prophet in prayer." Then the Prophet said to the people, "If some problem arises during prayers, then the men should say, Subhan Allah!; and the women should clap." (See Hadith No. 652, Vol. 1)
