verily those who give pledge to you they are giving pledge to allah. the hand of allah is over their hands. then whosoever breaks his pledge breaks it only to his own harm and whosoever fulfills what he has the covenants he makes with allah he will bestow on 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
