Ibn Abbaas (radiaAllaahu anhu) narrated that the Messenger of Allaah (sallaAllaahu ‘alayhi wa sallam) said:
“There are no days on which righteous deeds are more beloved to Allaah than these ten days.” They said: “Not even jihad for the sake of Allaah?” He said: “Not even jihad for the sake of Allaah, unless a man goes out himself for jihad taking his wealth with him and does not come back with anything.”
