﴿ فَكُلِى وَٱشْرَبِى وَقَرِّى عَيْنًۭا ۖ فَإِمَّا تَرَيِنَّ مِنَ ٱلْبَشَرِ أَحَدًۭا فَقُولِىٓ إِنِّى نَذَرْتُ لِلرَّحْمَٰنِ صَوْمًۭا فَلَنْ أُكَلِّمَ ٱلْيَوْمَ إِنسِيًّۭا ﴾

“Eat, then, and drink, and let thine eye be gladdened! And if thou shouldst see any human being, convey this unto him: `Behold, abstinence from speech have I vowed unto the Most Gracious; hence, I may not speak today to any mortal.”

(So eat) the date (and drink) from the stream (and be consoled) by the birth of Jesus (pbuh). (And if thou meetest any mortal) and if you meet any human being, after today (say: Lo! I have vowed a fast unto the Beneficent, and may not speak this day to any mortal) and then be silent until Jesus speaks after you.
