Aal-i-Imraan 41

قَالَ رَبِّ ٱجْعَل لِّىٓ ءَايَةً قَالَ ءَايَتُكَ أَلَّا تُكَلِّمَ ٱلنَّاسَ ثَلَٰثَةَ أَيَّامٍ إِلَّا رَمْزًا وَٱذْكُر رَّبَّكَ كَثِيرًا وَسَبِّحْ بِٱلْعَشِىِّ وَٱلْإِبْكَٰرِ ﴿٤١﴾

Qala rabbi ijAAal lee ayatan qala ayatuka alla tukallima alnnasa thalathata ayyamin illa ramzan waothkur rabbaka katheeran wasabbih bialAAashiyyi waalibkari

He said: "O my Lord! Make a sign for me." Allah said: "Your sign is that you shall not speak to mankind for three days except with signals. And remember your Lord much (by praising Him again and again), and glorify (Him) in the afternoon and in the morning." The Noble Quran
