Hadith 324
Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) said: "There are no days in which righteous deeds are more beloved to Allah than these ten days." We asked: "O Messenger of Allah! Not even striving in the way of Allah?" The Prophet (peace and blessings be upon him) said: "Not even striving in the way of Allah, except for a man who goes out with his life and wealth and returns with nothing of it (i.e., he sacrifices both)."
