فَكُلِى وَٱشْرَبِى وَقَرِّى عَيْنًا ۖ فَإِمَّا تَرَيِنَّ مِنَ ٱلْبَشَرِ أَحَدًا فَقُولِىٓ إِنِّى نَذَرْتُ لِلرَّحْمَـٰنِ صَوْمًا فَلَنْ أُكَلِّمَ ٱلْيَوْمَ إِنسِيًّا
Fakulee washrabee wa qarree 'ainaa; fa immaa tarayinnna minal bashari ahadan faqooleee innee nazartu lir Rahmaani sawman falan ukallimal yawma insiyyaa
So eat and drink and be comforted. And if you see anyone at all, say: 'I have vowed a fast to the Most Merciful, so I will not speak to any human today.'
