KHUBAIB خبيب
Son of ‘Ada. One of the early martyrs of Islam. Being perfidiously sold to the Quraish, he was by them put to death in a most cruel manner, being mutilated and impaled. When at the stake and in the midst of his tortures, he was asked whether he did not wish Muhammad was in his place, and he answered, “I would not wish to be with my family, my substance, and my children, on condition that Muhammad was only pricked by a thorn.” When bound to the stake, his enemies said, “Now abjure Islam, and we will let you go.” He replied, “Not for the whole world.”
Sir William Muir says: “I see no reason to doubt the main facts of the story.” (Life of Mahomet, new ed. p, 286.)
