قَالَ رَبِّ ٱجْعَل لِّىٓ ءَايَةًۭ ۖ قَالَ ءَايَتُكَ أَلَّا تُكَلِّمَ ٱلنَّاسَ ثَلَٰثَةَ أَيَّامٍ إِلَّا رَمْزًۭا ۗ وَٱذْكُر رَّبَّكَ كَثِيرًۭا وَسَبِّحْ بِٱلْعَشِىِّ وَٱلْإِبْكَٰرِ
He said: My Lord! Appoint a token for me. (The angel) said: The token unto thee (shall be) that thou shalt not speak unto mankind three days except by signs. Remember thy Lord much, and praise (Him) in the early hours of night and morning.

Narrated Abu Huraira:
I said to Allah's Messenger (ﷺ) "I hear many narrations (Hadiths) from you but I forget them." Allah's Apostle said, "Spread your Rida' (garment)." I did accordingly and then he moved his hands as if filling them with something (and emptied them in my Rida') and then said, "Take and wrap this sheet over your body." I did it and after that I never forgot any thing. Narrated Ibrahim bin Al-Mundhir: Ibn Abi Fudaik narrated the same as above (Hadith...119) but added that the Prophet (ﷺ) had moved his hands as if filling them with something and then he emptied them in the Rida' of Abu Huraira.
