It is narrated by Safwan bin Muhriz that Jundab bin Abdullah al-Bajali during the stormy days of Ibn Zubair sent a message to Asas bin Salama (RA) : Gather some men of your family so that I should talk to them. He (Asas) sent a messenger to them (to the members of his family). When they had assembled, Jundab came there with a yellow hooded cloak on him, He said: Talk what you were busy in talking. The talk went on by turns, till there came his (Jundabs) turn. He took off the hooded cloak from his head and said: I have come to you with no other intention but to narrate to you a hadith of your Apostle: Verily the Messenger of Allah ﷺ sent a squad of the Muslims to a tribe of the polytheists. Both the armies confronted one another. There was a man among the army of polytheists who (was so dashing that), whenever he intended to kill a man from among the Muslims, he killed him. Amongst the Muslims too was a man looking forward to (an opportunity of) his (the polytheists) unmindfulness. He (the narrator) said: We talked that he was Usama b, Zaid. When he raised his sword, he (the soldier of the polytheists) uttered:" There is no god but Allah," but he (Usama bin Zaid) killed him. When the messenger of the glad tidings came to the Apostle ﷺ he asked him (about the events of the battle) and he informed him about the man (Usama) and what he had done He (the Prophet ﷺ of Allah) called for him and asked him why he had killed him. He (Usama) said: Messenger of Allah, he struck the Muslims and killed such and such of them. And he even named some of them. (He continued): I attacked him and when he saw the sword he said: There is no god but Allah. The Messenger of Allah ﷺ said: Did you kill him? He (Usama) replied in the affirmative. He (the Holy Prophet) remarked: What would you do with:" There is no god but Allah," when he would come (before you) on the Day of Judgment? He (Usama) said: Messenger of Allah, beg pardon for me (from your Lord). He (the Holy Prophet) said: What would you do with:" There is no god but Allah" when he would come (before you) on the Day of Judgment? He (the Holy Prophet) added nothing to it but kept saying: What would you do with:" There is no god but Allah," when he would come (before you) on the Day of Judgment?
