Sunan Ibn Majah 1727

It was narrated from Ibn ‘Abbas that the Messenger of Allah (ﷺ) said:“There are no days during which righteous deeds are more beloved to Allah than these days,” meaning the (first) ten days of Dhul- Hijjah. They said: “O Messenger of Allah! Not even Jihad in the cause of Allah?” He said: “Not even Jihad in the cause of Allah, unless a man goes out with himself and his wealth and does not bring anything back.”
