فَكُلِى وَٱشْرَبِى وَقَرِّى عَيْنًا ۖ فَإِمَّا تَرَيِنَّ مِنَ ٱلْبَشَرِ أَحَدًا فَقُولِىٓ إِنِّى نَذَرْتُ لِلرَّحْمَـٰنِ صَوْمًا فَلَنْ أُكَلِّمَ ٱلْيَوْمَ إِنسِيًّا
fakulī wa-ish'rabī waqarrī ʿaynan fa-immā tarayinna mina l-bashari aḥadan faqūlī innī nadhartu lilrraḥmāni ṣawman falan ukallima l-yawma insiyyan
so eat, drink, be glad, and say to anyone you may see: “I have vowed to the Lord of Mercy to abstain from conversation, and I will not talk to anyone today.”’
"So eat and drink and be glad. And if you see any human being, say: ‘Verily! I have vowed a fast unto the Most Gracious (Allâh) so I shall not speak to any human being this day.’"
