"I heard the Messenger of Allah say: 'The deceased is punished in his grave due to the wailing over him."'
Sunan an-Nasa'i Book 21, Hadith 36
← Previous Hadith when the Messenger of Allah accepted the women's oath of allegiance, he accepted their pledge that they would not wail (over the death). They said: "O Messenger of Allah, there are women who helped us to mourn during the Jahiliyyah should we help them to mourn?" The Messenger of Allah said: "There is no helping to mourn in Islam."

Sunan an-Nasa'i Book 21, Hadith 35 Next Hadith → "The deceased is punished due to his family's wailing for him." A man said to him: "A man died in Khurasan and his family wailed for him here; will he be punished due to his family's wailing?" He said: "The Messenger of Allah spoke the truth and you are a liar."
