Abu Hurairah (May Allah be pleased with him) reported:
The Messenger of Allah sallallahu alayhi wasallam said,
“On no days is the worship of Allah desired more than in the first 10 days of Zil-Hijjah.
The fast of each of these days is equal to the fast of a whole year, and the
IBAADAT of each of these nights is equal to the IBAADAT of LAILATUL QADR”.
(Tirmizi & Ibn Maajah)
