Narrated Ibn Abbas (RadhiAllahu 'anhu):
The Prophet (salAllahu alayhi wa sallam) said:
"No good deeds done on other days are superior to those done on these (first ten days of Dhul Hijja)." Then some companions of the Prophet said, "Not even Jihad?" He replied, "Not even Jihad, except that of a man who does it by putting himself and his property in danger (for Allah's sake) and does not return with any of those things."
[Sahih Bukhari - Book #15 - Hadith #86]
