Jami' at-Tirmidhi — Hadith #28795

Qutaibah told us, on the authority of Malik ibn Anas, on the authority of Abdullah ibn Dinar, on the authority of Ibn Umar, on the authority of the Prophet, may God bless him and grant him peace, he said “Any man who says to his brother he is an infidel, then one of them has committed a sin against him.” This is a good, authentic, and strange hadith. The meaning of his saying “ba” means he approved. .
