فَإِذَا قَضَيْتُم مَّنَٰسِكَكُمْ فَٱذْكُرُوا۟ ٱللَّهَ كَذِكْرِكُمْ ءَابَآءَكُمْ أَوْ أَشَدَّ ذِكْرًۭا ۗ فَمِنَ ٱلنَّاسِ مَن يَقُولُ رَبَّنَآ ءَاتِنَا فِى ٱلدُّنْيَا وَمَا لَهُۥ فِى ٱلْءَاخِرَةِ مِنْ خَلَٰقٍۢ
And when ye have completed your devotions, then remember Allah as ye remember your fathers or with a more lively remembrance. But of mankind is he who saith: "Our Lord! Give unto us in the world," and he hath no portion in the Hereafter.
