The Prophet ﷺ said, "He is not one of us who strikes his cheeks, tears his garments, and cries out with the calls of the days of ignorance."
أخبرنا محمد بن بشار قال حدثنا يحيى قال حدثنا سفيان قال حدثني زبيد عن إبراهيم عن مسروق
أن النبي ﷺ قال ليس منا من ضرب الخدود وشق الجيوب ودعا بدعوى الجاهلية
Bukhari narrated it in the Book of Funerals, Chapter "He is not one of us who tears his garments," Hadith: 1294, from the hadith of Sufyan Thawri, with the same wording, and it is also found in al-Kubra, Hadith: 1989.* Yahya is Ibn Saeed Qattan.
