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.
