يَغْفِرْ لَكُم مِّن ذُنُوبِكُمْ وَيُؤَخِّرْكُمْ إِلَىٰٓ أَجَلٍۢ مُّسَمًّى ۚ إِنَّ أَجَلَ ٱللَّهِ إِذَا جَآءَ لَا يُؤَخَّرُ ۖ لَوْ كُنتُمْ تَعْلَمُونَ
That He may forgive you somewhat of your sins and respite you to an appointed term. Lo! the term of Allah, when it cometh, cannot be delayed, if ye but knew.
