(302) Chapter: Prohibition of Bewailing the Deceased

Ibn Mas'ud (May Allah be pleased with him) said:
The Messenger of Allah (ﷺ) said, "He who (on befalling a calamity) slaps his cheeks, tears his clothes and follows the ways and traditions of the Days of Ignorance is none of us."

[Al-Bukhari and Muslim].

Commentary: "He is none of us'' here signifies that he is not following the ways of Muslims. "The ways and traditions of the Days of Ignorance'' means here wailing, i.e., `Alas! my lion, my moon, my support, one whose death has rendered his children orphan etc., etc.' This is a grave sin and there is a stern warning that one who does it, is in danger of losing his Faith because by doing so one, in fact, expresses resentment against Allah's Command.
