From Sahih Muslim (Hadith 2146):
Abu Burda narrated on the authority of his father that when 'Umar was wounded Suhaib uttered (loudly in lamentation):O brother! Upon this 'Umar said: Suhaib, did you not know that the Messenger of Allah (ﷺ) said:" The dead is punished because of the lamentation of the living"?
