Hazrat Abu Hurayrah (Radiyallahu Anhu) reports that Rasulullah (Sallallahu Alayhi Wasallam) said: “There are no days more beloved to Allah Ta’ala that he be worshipped in than the ten days of Dhul Hijjah. Fasting on one of these days (excluding the tenth) is equivalent to the fasting of an entire year and spending one of these nights in theibaadah of Allah Ta’ala is equivalent to spending the night of Qadr in ibaadah.”
