Verse 26

فَكُلِى وَٱشْرَبِى وَقَرِّى عَيْنًا فَإِمَّا تَرَيِنَّ مِنَ ٱلْبَشَرِ أَحَدًا فَقُولِىٓ إِنِّى نَذَرْتُ لِلرَّحْمَـٰنِ صَوْمًا فَلَنْ أُكَلِّمَ ٱلْيَوْمَ إِنسِيًّا

Then eat and drink and brighten your eyes, afterwards when you see any person, say, I have indeed promised the All Gracious a vow of silence, and therefore, I will not speak to any one today.
