[Machine] Ubayy ibn Khalaf came to the Prophet ﷺ on the day of Uhud and some believers intercepted him. The Messenger of Allah ﷺ ordered them to let him go, so Mus`ab ibn `Umayr, the brother of Bani Abd Ad-Dar, intercepted him and saw a slit in Ubayy's throat between his wide neck and his white armor. Mus`ab stabbed him with his spear, causing Ubayy to fall off his horse, but no blood came out from his stab; instead, it broke one of his ribs. His companions approached him while he was writhing in pain, and they said to him, "This is just a scratch, what made you so weak?" He reminded them of the words of the Messenger of Allah ﷺ that he said, "Rather, I have slain Ubayy!" Then he said, "By the One in Whose Hand is my soul! If it was not for my status before Allah, the inhabitants of Dhi Al-Majaz would have all been killed." Ubayy died in the fire, a wretched fate for the people of Sa`ir before he could reach Makkah. Allah then revealed the Ayah: "And you threw not when you did throw, but Allah threw" (8:17).
