Do not behave like that (foolish) person who, after having worked so hard to knit something, pulls the thread and breaks it into pieces! Remember this example when you want to break your promises (even the ones which are not made by taking God as a witness for its fulfillment) no matter how powerful you (or your group) are. This is one way that God puts you to the test. Remember, on the Day of Resurrection, He will play back for you whatever you were disputing among yourselves.
