Surah Maryam, Verse 26

فَكُلِي وَٱشۡرَبِي وَقَرِّي عَيۡنٗاۖ فَإِمَّا تَرَيِنَّ مِنَ ٱلۡبَشَرِ أَحَدٗا فَقُولِيٓ إِنِّي نَذَرۡتُ لِلرَّحۡمَٰنِ صَوۡمٗا فَلَنۡ أُكَلِّمَ ٱلۡيَوۡمَ إِنسِيّٗا٢٦

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 and drink and be contented. And if you see from among humanity anyone, say, 'Indeed, I have vowed to the Most Merciful abstention, so I will not speak today to [any] man.'"
