From Sahih Muslim (Hadith 2147):
Abu Musa reported that when 'Umar was wounded, there came Suhaib from his house and went to 'Umar and stood by his side, and began to wail. Upon this 'Umar said: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)
