43. Amīr al-mu’minīn, peace be upon him, said about Khabbāb ibn al-Aratt : May Allāh have mercy on Khabbāb ibn al-Aratt since he accepted Islam willingly, immigrated (from Mecca) obediently, remained content with what sufficed him, was pleased with Allāh and lived the life of a mujāhid (holy soldier).
 Khabbāb ibn al-Aratt was a distinguished companion of the Holy Prophet and was one of the early muhājirun (immigrants). He suffered various sorts of hardships at the hands of the Quraysh. He was made to stand in the scorching sun, and to lie on fire but he did not for any reason abandon the side of the Holy Prophet. He accompanied the Holy Prophet in Badr and other battles. He supported Amīr al-mu’minīn in Ṣiffīn and Nahrawān. He had left Medina and settled in Kūfah. Thus, he died here in 39 A.H. at the age of 73, Amīr al-mu’minīn led his funeral prayer and he was buried outside Kūfah. Amīr al-mu’minīn uttered these mercy-invoking words standing on his grave.
