Mishkat al-Masabih #1382

Ibn ‘Abbas reported God's Messenger as saying, “There are no days in which a good deed is more pleasing to God than these ten days.” On being asked whether not even jihad in God’s path were as pleasing, he replied, “Not even jihad in God’s path, except when a man goes out in person with his property and loses both life and property.” Bukhari transmitted it.
