Ibn 'Abbas (May Allah be pleased with them) reported

The Messenger of Allah (ﷺ) said, "There are no days during which the righteous action is so pleasing to Allah than these days (i.e., the first ten days of Dhul-Hijjah)." He was asked: "O Messenger of Allah, not even Jihad in the Cause of Allah?" He (ﷺ) replied, "Not even Jihad in the Cause of Allah, except in case one goes forth with his life and his property and does not return with either of it."
