The Prophet (ﷺ) sent (an army unit under the command of) Khalid bin Al-Walid to fight against the tribe of Bani Jadhima and those people could not express themselves by saying, "Aslamna," but they said, "Saba'na! Saba'na! " Khalid kept on killing some of them and taking some others as captives, and he gave a captive to everyone of us and ordered everyone of us to kill his captive. I said, "By Allah, I shall not kill my captive and none of my companions shall kill his captive!" Then we mentioned that to the Prophet (ﷺ) and he said, "O Allah! I am free from what Khalid bin Al-Walid has done," and repeated it twice.

← Previous Hadith Allah's Messenger (ﷺ) said, "The most hated person in the sight of Allah, is the most quarrelsome person."

Sahih al-Bukhari Book 93, Hadith 50 Next Hadith → 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 (ﷺ) 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 (ﷺ) standing behind him. The Prophet (ﷺ) beckoned him to carry on by waving his hand. Abu Bakr stood there for a while, thanking Allah for the saying of the Prophet (ﷺ) 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 (ﷺ) in prayer." Then the Prophet (ﷺ) 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)
