It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them): The Noble Prophet (peace and blessings be upon him) said: "There are no days in which righteous deeds are more virtuous than the ten days of Dhul-Hijjah." It was asked: "Not even Jihad has such virtue?" He replied: "Not even Jihad, except for a person who goes out putting his life and wealth in danger, and returns with nothing." (i.e., he sacrificed both his life and wealth).

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "There is no righteous deed more beloved to Allah, the Mighty and Majestic, than the deed performed by a servant during the ten days of Dhul-Hijjah." It was asked: Not even striving in the way of Allah, the Mighty and Majestic? He said: "Not even striving in the way of Allah, except for a man who goes out with his self and his wealth and returns with none of them." The narrator said: For this reason, Sayyiduna Sa'id bin Jubair (may Allah be pleased with him) used to exert himself in worship beyond his capacity during the first ten days of Dhul-Hijjah.
