فَكُلِي وَاشْرَبِي وَقَرِّي عَيْنًا ۖ فَإِمَّا تَرَيِنَّ مِنَ الْبَشَرِ أَحَدًا فَقُولِي إِنِّي نَذَرْتُ لِلرَّحْمَٰنِ صَوْمًا فَلَنْ أُكَلِّمَ الْيَوْمَ إِنْسِيًّا 26
"So eat and drink and cool (thine) eye. And if thou dost see any man, say, 'I have vowed a fast to (Allah) Most Gracious, and this day will I enter into not talk with any human being'"
