3:41
قَالَ رَبِّ ٱجْعَل لِّ ىٓ ءَايَةً قَالَ ءَايَتُ كَ أَ لَّا تُكَلِّمَ ٱل نَّاسَ ثَلَٰثَةَ أَيَّامٍ إِلَّا رَمْزًا وَ ٱذْكُر رَّبَّ كَ كَثِيرًا وَ سَبِّحْ بِ ٱلْ عَشِىِّ وَ ٱلْ إِبْكَٰرِ
He said, "My Lord, make for me a sign." He Said, "Your sign is that you will not [be able to] speak to the people for three days except by gesture. And remember your Lord much and exalt [Him with praise] in the evening and the morning."
