From Sahih Muslim (Hadith 2779):
Abu Huraira (Allah be pleased with him) reported:We were talking about Lailat-ul-Qadr in the presence of the Messenger of Allah (ﷺ) and he said: He who amongst you remembers (the night) when the moon arose and it was like a piece of plate (at the fag end of the month in a state of waning)
