surely those who swear allegiance to you do but swear allegiance to allah the hand of allah is above their hands. therefore whoever breaks he breaks it only to the injury of his own soul and whoever fulfills what he has covenanted with allah he will grant him a mighty reward.
إن الذين يبايعونك إنما يبايعون الله يد الله فوق أيديهم فمن نكث فإنما ينكث على نفسه ومن أوفى بما عاهد عليه الله فسيؤتيه أجرا عظيما
