Surah Al-Fath Verse 10 - English Translation by Ali Bakhtiari Nejad
Surah Al-Fathإِنَّ ٱلَّذِينَ يُبَايِعُونَكَ إِنَّمَا يُبَايِعُونَ ٱللَّهَ يَدُ ٱللَّهِ فَوۡقَ أَيۡدِيهِمۡۚ فَمَن نَّكَثَ فَإِنَّمَا يَنكُثُ عَلَىٰ نَفۡسِهِۦۖ وَمَنۡ أَوۡفَىٰ بِمَا عَٰهَدَ عَلَيۡهُ ٱللَّهَ فَسَيُؤۡتِيهِ أَجۡرًا عَظِيمٗا
Those who pledge allegiance to you are indeed pledging allegiance to God, God’s hand is above their hands (as a sign of God's pledge). So whoever breaks (his pledge), he only breaks it against himself, and whoever fulfills what he promised to God, then He is going to give him a great reward
