It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) sent Sayyiduna Khalid bin Walid (may Allah be pleased with him) towards the tribe of Banu Jadhimah. He invited this tribe to Islam, but they could not say in a good manner that they had become Muslims. Instead of saying "We have accepted Islam (Aslamna)," they started saying: "We have turned away, we have turned away (Saba'na, Saba'na)." On the other side, Sayyiduna Khalid (may Allah be pleased with him) began to imprison and kill them, and each one of us was given a prisoner, until when morning came, Sayyiduna Khalid ordered that each man should kill his own prisoner. Sayyiduna Ibn Umar (may Allah be pleased with him) said: By Allah! Neither will I kill my prisoner, nor will any man among my companions kill his prisoner. Then, when they came to the Messenger of Allah (peace and blessings be upon him) and informed him of the action of Sayyiduna Khalid (may Allah be pleased with him), the Messenger of Allah (peace and blessings be upon him) raised both his hands and said: O Allah! I declare myself free before You from what Khalid has done (i.e., I have nothing to do with this action). The Messenger of Allah (peace and blessings be upon him) said this sentence twice.
