Bless Muhammad
Indeed, those who pledge allegiance to you are actually pledging allegiance to Allah. Allah’s hand is above their hands. So, whoever breaks his word does so to his own loss, and whoever fulfils his covenant with Allah, He will grant him a great reward.
48:10Lo! 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.
