your lord is the forgiving one the possessor of mercy. if he had to take them to task for the wrongs they have done he would have hastened their punishment. they have an appointed time beyond which there will be no escape for them.
وربك الغفور ذو الرحمة لو يؤاخذهم بما كسبوا لعجل لهم العذاب بل لهم موعد لن يجدوا من دونه موئلا
