فَكُلِى وَٱشْرَبِى وَقَرِّى عَيْنًۭا ۖ فَإِمَّا تَرَيِنَّ مِنَ ٱلْبَشَرِ أَحَدًۭا فَقُولِىٓ إِنِّى نَذَرْتُ لِلرَّحْمَٰنِ صَوْمًۭا فَلَنْ أُكَلِّمَ ٱلْيَوْمَ إِنسِيًّۭا
So eat and drink and be consoled. And if thou meetest any mortal, say: Lo! I have vowed a fast unto the Beneficent, and may not speak this day to any mortal.
