Surah Al-Fath Verse 10 - English Translation by Dr Munir Munshey
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
Indeed, those who took the oath of allegiance to you, (oh Muhammad, SAW), were in fact pledging their allegiance to Allah. It was actually Allah´s hand over their hand! So now, whoever violates (the pledge) does so to his own detriment. Allah will grant a generous reward to the one who (faithfully) fulfills the covenant with Him
