those who swear allegiance to you do indeed in fact swear allegiance to allah allahs hand* of power is above their hands so whoever breaches his oath has breached his own greater promise and whoever fulfils the covenant he has with allah – so very soon allah will bestow upon him a great 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
