It was narrated from Abu Hurairah (RA) that the Messenger of Allah ﷺ said: "There are no days in this world during which worship is more beloved to Allah,Glorious is He, than the (first) ten days (of Dhul-Hijjah). Fasting one of these days is equivalent to " fasting for a year, and one night of them is equal to Lailatul-Qadr."(Daif)
