It is narrated from Hasan that he says: The Messenger of Allah, peace and blessings be upon him, said: "There are no drops more beloved to Allah Almighty than these two drops: one is the drop of blood that falls in the way of Allah, and the other is the tear that falls from the eye of a person out of fear of Allah, who stands before Allah in the middle of the night. And there are no sips more beloved to Allah than these two sips: one is the painful and distressing sip which a person accepts with good patience and endurance, and the other is the sip of anger which a person restrains."
