It is narrated from Sayyiduna Sa’d bin Malik (may Allah be pleased with him), he said: O Messenger of Allah! Indeed, Allah Almighty has granted me healing from the polytheists, so grant me this sword as a gift. The Prophet (peace and blessings be upon him) said: This sword is neither mine nor yours, so put it down here. So I put it down, then I returned and said: Perhaps this sword will be given to a servant who cannot display bravery like mine. Meanwhile, a man called me from behind, I said: It seems that a special command has been revealed about me. The Prophet (peace and blessings be upon him) said: You had asked me for this sword, while it was not mine; now it has been gifted to me, therefore now it is yours. Then this verse was revealed: They ask you about the spoils (anfal); say, the spoils are for Allah and His Messenger.
