Surah Al-Fath Verse 10 - English Translation by Shabbir Ahmed
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
Behold, all who pledge allegiance to you (O Prophet), in fact pledge allegiance to Allah. The Hand of Allah is above their hands. Hence, whoever shatters his pledge, shatters his own 'Self'. And whoever keeps his pledge with Allah, to him He will grant a Supreme Reward
