Riyad as-Salihin, 1586

Abu Sa'id Al-Khudri (May Allah be pleased with him) said:

The Prophet (ﷺ) 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." <b>[Muslim]</b>.

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

‏ ‏(‏‏(‏رواه مسلم‏)‏‏)‏‏.‏

<b>Guidance from the Hadiths:</b><br> 1) The Hadith warns of treachery as one of the major sins.<br> 2) The greater the treachery is the greater will be the scandal and sinfulness of the treacherous on the Day of Judgment. That is, treachery committed against one person is not equal to that committed against a group or community. Hence, one can visualize how huge the sin of those who are treacherous towards the Muslims is. They only care for satiating their own desires and attaining their own interests. Allah Almighty is their Reckoner in the worldly life and the Hereafter.
