Qur'an 3:41 · Aal-i-Imraan

قَالَ رَبِّ ٱجْعَل لِّىٓ ءَايَةًۭ ۖ قَالَ ءَايَتُكَ أَلَّا تُكَلِّمَ ٱلنَّاسَ ثَلَٰثَةَ أَيَّامٍ إِلَّا رَمْزًۭا ۗ وَٱذْكُر رَّبَّكَ كَثِيرًۭا وَسَبِّحْ بِٱلْعَشِىِّ وَٱلْإِبْكَٰرِ

(41) 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."
