1. My father, may Allah grant him mercy, said: We were told by Sa’d bin Abdullah, from Ahmad bin Muhammed bin Isa, from Abbas bin Ma’ruf, from Safwan bin Yahya, from Ibn Maskan, from Muhammed bin Muslim, that he said: I said to Abu Abdillah, peace be upon him: «Cruel, moreover, a bastard.» (68:13) He said: The great cruelty is disbelief, and the villainous is the one who wantons with his disbelief.
