It is narrated from Sayyiduna Salamah bin Akwa’ (may Allah be pleased with him) that on the occasion of the Battle of Khaybar, my brother (according to another narration, my uncle) fought fiercely in the company of the Prophet (peace and blessings of Allah be upon him), but during the battle, his sword slipped and struck himself, and he was martyred by its blade. The noble Companions (may Allah be pleased with them all) began to express doubts and whisper among themselves about him, saying that he was killed by his own weapon. When the Prophet (peace and blessings of Allah be upon him) returned, I said: O Messenger of Allah! (peace and blessings of Allah be upon him) May I have your permission to recite rajaz poetry? The Prophet (peace and blessings of Allah be upon him) granted permission. Sayyiduna Umar (may Allah be pleased with him) said: Speak thoughtfully. While reciting poetry, I said: By Allah! If it were not for Allah, we would never have been guided, nor given charity, nor prayed. The Prophet (peace and blessings of Allah be upon him) said: You have spoken the truth. I further said: O Allah! Send down tranquility upon us and grant us steadfastness when facing the enemy, for the polytheists have girded themselves against us in rebellion. When I completed my rajaz poetry, the Prophet (peace and blessings of Allah be upon him) asked: Who composed these verses? I replied: My brother composed them. The Prophet (peace and blessings of Allah be upon him) said: May Allah’s mercy descend upon him. I said: O Messenger of Allah! (peace and blessings of Allah be upon him) Some people are hesitant to perform his funeral prayer and say that he died by his own weapon. The Prophet (peace and blessings of Allah be upon him) said: He was martyred as a striving mujahid. In another chain, it is also mentioned that the Prophet (peace and blessings of Allah be upon him) said: Those who are hesitant to perform his funeral prayer are mistaken; he was martyred as a striving mujahid and will receive a double reward. Saying this, the Prophet (peace and blessings of Allah be upon him) gestured with two fingers.
