وعن أبي سعيد الخدري رضي الله عنه
أن النبي صلى الله عليه وسلم قال: «لكل غادر لواء عند استه يوم القيامة يرفع له بقدر غدره، ألا لا غادر أعظم غدرًا من أمير عامة»
The Prophet (sallallahu alayhi wa sallam) said, “Every one who breaks a covenant will have a flag by his buttocks on the Day of Resurrection. It will be raised higher according to the nature of his breach. Behold, there will be no greater a sin with respect to breaking the covenant than that of a ruler who breaks his covenant with the Muslim masses.”.
