يَغْفِرْ لَكُم مِّن ذُنُوبِكُمْ وَيُؤَخِّرْكُمْ إِلَىٰٓ أَجَلٍ مُّسَمًّى ۚ إِنَّ أَجَلَ ٱللَّهِ إِذَا جَآءَ لَا يُؤَخَّرُ ۖ لَوْ كُنتُمْ تَعْلَمُونَ
Allah will forgive you of your sins and delay you for a specified term. Indeed, the time [set by] Allah, when it comes, will not be delayed, if you only knew.' "
