Al-Fath 48:10

إِنَّ ٱلَّذِينَ يُبَايِعُونَكَ إِنَّمَا يُبَايِعُونَ ٱللَّهَ يَدُ ٱللَّهِ فَوْقَ أَيْدِيهِمْ ۚ فَمَن نَّكَثَ فَإِنَّمَا يَنكُثُ عَلَىٰ نَفْسِهِۦ ۖ وَمَنْ أَوْفَىٰ بِمَا عَٰهَدَ عَلَيْهُ ٱللَّهَ فَسَيُؤْتِيهِ أَجْرًا عَظِيمًۭا

Innal lazeena yubaayi'oonaka innamaa yubaayi'oonal laaha yadul laahi fawqa aydehim; faman nakasa fainnamaa yuankusu 'alaa nafsihee wa man awfaa bimaa 'aahada 'alihul laaha fasa yu'teehi ajran 'azeemaa

Those who swore fealty to you, (O Prophet), in fact swore fealty to Allah. The Hand of Allah is above their hands. So whoever breaks his covenant breaks it to his own hurt; and whoever fulfils the covenant that he made with Allah, He will bestow on him a great reward.
