[Machine] He heard the Messenger of Allah ﷺ say during his campaign to Khaybar, to 'Amir ibn al-Akwa' whose real name was Sinan: "Descend, O son of al-Akwa', and bring us some of your provisions." So he descended and began to recite the verses of the poetic ode: "By Allah, if not for you, we would not have been guided, nor believed, nor prayed. So send down tranquility upon us and make our footsteps firm. Surely, we will meet the disbelievers who have transgressed against us, and if they seek to harm us, we will retaliate." The Messenger of Allah ﷺ said to him: "May your Lord have mercy on you." 'Umar ibn al-Khattab said: "By Allah, it is obligatory. If we are granted victory through him, he will be killed during the Battle of Khaybar as a martyr." And it was reported to me that his own sword turned against him, so he spoke harshly to it while fighting, and it caused his death. The Muslims doubted him and said: "Only his own weapon killed him." So Salamah ibn 'Amr asked the Messenger of Allah ﷺ and informed him of what the people were saying about him. The Messenger of Allah ﷺ said: "Indeed, he is a martyr." So the Messenger of Allah ﷺ prayed for him, and the Muslims prayed for him.
