question #1 Sahih Muslim 1166, Book 13, Hadith 274 : What is the significance of seeking Lailat-ul-Qadr during the last week of Ramadan?

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.”
