your lord is forgiving owner of mercy. had it been his will to take them to task for what they earned he would have hastened their punishment but they have an appointed hour from which they will never escape.
وربك الغفور ذو الرحمة لو يؤاخذهم بما كسبوا لعجل لهم العذاب بل لهم موعد لن يجدوا من دونه موئلا
