(4) باب تَحْرِيمِ الْغَدْرِ
It is narrated on the authority of Abu Sa'id that the Messenger of Allah (ﷺ) said:
On the Day of Judgment there will be a flag for every person guilty of the breach of faith. It will be raised in proportion to the extent of his guilt; and there is no guilt of treachery more serious than the one committed by the ruler of men. (PT)
