If He were to impose blame upon them for what they earned, He would have hastened for them the punishment. Rather, for them is an appointment from which they will never find an escape. 58 All the townships afflicted with scourge are before your eyes. When they committed wrong, We destroyed them. For the destruction of each We had set a definite term. 59
