 2. By the ten nights (i.e. the first ten days of the month of Dhul-Hijjah)[1],
(V.89:2) Narrated Ibn ‘Abbâs رضي الله عنهما: The Prophet صلى الله عليه وسلم said, "No good deeds done on other days are superior to those done on these (first ten days of Dhul-Hijjah)." Then some Companions of the Prophet صلى الله عليه وسلم said, "Not even Jihâd ?" He replied, "Not even Jihâd, except that of a man who does it by putting himself and his property in danger (for Allâh’s sake) and does not return with any of those things." (Sahih Al-Bukhari, Vol.2, Hadith No.86).
