The Virtue of the Ten Days of Dhul Hijja

عن ابن عباس عن النبي صلى الله عليه وسلم أنه قال ما العمل في أيام أفضل منها في هذه قالوا ولا الجهاد قال ولا الجهاد إلا رجل خرج يخاطر بنفسه وماله فلم يرجع بشيء (بخاري 1/132)

Hazrat Abdullah ibn Abbas (Radhiyallahu Anhuma) reports that Nabi (Sallallahu Alaihi Wasallam) said, “There is no virtuous deed carried out in any day of the year that can be equal to the reward of (that  virtuous deed) carried out in these ten days of Dhul Hijja”. The Sahabah asked, “Not even Jihaad?” Rasulullah (Sallallahu Alaihi Wasallam) replied, “Not even Jihaad, except for the one who endangers his life and wealth (in Jihaad) and does not return with anything (i.e. the Jihad carried out in the ten days of Dhul Hijja is more virtuous than Jihaad during the rest of the year except for that Mujaahid who gains martyrdom).
