Oaths and Vows
1. Do not take oaths in the name of anyone other than Allah. For example, do not take oaths in the name of your children, your health, your eyes, etc. It is a sin to take such oaths. If you mistakenly utter such oaths, you should immediately recite the kalimah.
2. Similarly, do not take oaths of this nature: “If I am lying, may I lose my îmân“, even if what you are saying is the truth.
3. If, out of anger, you take an oath which is sinful to fulfil, then breach such an oath and pay kaffârah, e.g. you take an oath that you will not speak to your father or your mother, or any similar oath.
