Kilab.
He was the chieftain of Quraysh and their commander on the day of Uhud and on the day of the Trench. He had certain failings and difficult deeds, but Allah rescued him through Islam on the day of the Conquest, and he accepted it almost under duress, fearful as he was. A few days later, however, his Islam became sound.
He was counted among the shrewdest of the Arabs, a man of judgment and honor among them. He was present at Hunayn, and his in-law, the Messenger of Allah ﷺ, granted him a hundred camels and forty uqiyyahs of silver from the spoils to win his heart thereby (1). After that he abandoned the worship of Hubal and inclined fully to Islam.
He took part in the fighting at al-Taʾif, where one of his eyes was struck out; the other was lost on the day of Yarmuk, by which time—Allah willing—his faith had become excellent, for on that day he was urging the people to jihad. He fought under the banner of his son Yazid, crying, “O help of Allah, draw near! (2)”
He would stand over the battle formations (3), exhorting them and saying:
“Fear Allah, fear Allah! You are the helpers of Islam and the bulwark (4) of the Arabs, while those are the helpers of idolatry and the bulwark of Rome. O Allah, this is one of Your days; O Allah, send down Your victory.”
