Commentary: In this, there is an allusion to the noble verse: «نُورُهُمْيَسْعَىٰبَيْنَأَيْدِيهِمْوَبِأَيْمَانِهِمْيَقُولُونَرَبَّنَاأَتْمِمْلَنَانُورَنَاوَاغْفِرْلَنَا ۖ»[تحريم۔80] “Their light will run before them and on their right; they will say: ‘Our Lord! Perfect our light for us, and forgive us.’”
