Abu Huraira (Allah be pleased with him) reported Allah's Messenger (ﷺ) as saying: I was shown Lailat-ul-Qadr; then some members of my family awoke me up, then I was caused to forget it. So seek it in the last week. Harmala said: (The Prophet did not say: " I was made to forget," but he stated): " But I forgot it"
