Translations
Indeed, those who pledge allegiance to you, [O Muhammad] - they are actually pledging allegiance to Allah. The hand of Allah is over their hands. So he who breaks his word only breaks it to the detriment of himself. And he who fulfills that which he has promised Allah - He will give him a great reward
Saheeh International
Lo! those who swear allegiance unto thee (Muhammad), swear allegiance only unto Allah. The Hand of Allah is above their hands. So whosoever breaketh his oath, breaketh it only to his soul's hurt; while whosoever keepeth his covenant with Allah, on him will He bestow immense reward
