Jami' al-Tirmidhi The Book on Blood Money Abdur Rahman bin 'Amr عبد الرحمن بن عمرو بن سهل الأنصاري Abdur-Razzaq عبد الرزاق بن همام al-Zuhri ابن شهاب الزهري‎, محمد بن مسلم Ma'mar bin Rashid معمر بن راشد Sa'id bin Zayd Salmah bin Shbyb سلمة بن شبيب Talha bin 'Abdullah طلحة بن عبد الله بن عوف الزهري that the Prophet (ﷺ) said: “Indeed, whoever kills a Mu’ahid that has a covenant from Allah and a covenant from His Messenger (ﷺ), then he has violated the covenant with Allah and the covenant of His Messenger, so he shall not smell the fragrance of Paradise; even though its fragrance can be sensed from the distance of seventy autumns.” https://parallelquran.com/hadith/jami-al-tirmidhi-1404/
