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"?
Sahih Muslim Book 11, Hadith 24
← Previous Hadith When 'Umar was wounded he fainted, and there was a loud lamentation over him. When he regained consciousness he said: Didn't you know that the Messenger of Allah (ﷺ) said:" The dead is punished because of the weeping of the living"?

Sahih Muslim Book 11, Hadith 23 Next Hadith → What are you weeping for? Are you weeping for me? He said: By Allah, it is for you that I weep, O Commander of the believers. He said: By Allah, you already know that the Messenger of Allah (ﷺ) had said: He who is lamented upon is punished. I made a mention of it to Musa b. Talha, and he said that 'A'isha told that it concerned the Jews (only).
