وَإِنَّ رَبَّكَ لَهُوَ الْعَزِيزُ الرَّحِيمُ (9)
(26:9) The fact is that your Lord is Mighty as well as Merciful. *6
*6) That is, "He has the power and ability to annihilate completely anyone whom He wills to punish, but it is His mercy that He dces not hasten to punish the wrung-doer, but gives him respite for years and centuries to allow him time to think, understand and mend his ways, and is ever ready to forgive the sins of a lifetime if the sinner offers repentance but once."
