Anas reported that when 'Umar b. Khattab was wounded Hafsa lamented for him. Upon this he said: O Hafsa, did you not hear the Messenger of Allah (may peace be upon him) saying:" One who is lamented would be punished"? Suhaib also lamented over him. 'Umar told him also: O Suhaib, didn't you know that one who is lamented is punished?
