Before one starts writing a taweez a proper has to be selected for this purpose. The room should be clean. If there is a carpet on the floor than it should be ensured that it is clean or paak. Sometimes infants pass urine so if there is any such doubt then wash the carpet. Avoid using a room that has an attached bathroom-toilet. This can put you in trouble. If you live in a mansion which has 2-3 storey then select a room that is on the top floor of the building.
While you write the taweez, women who are have menstrual cycle should not come into your room and neither should you eat food that has been cooked by them. The room should be such that you can ignite incense sticks in it and there should not be any pictures or imagery in it. There should not be any television, music, filthy socks, shoes, or anything that stinks. The cleaner the room, the more spiritual powers will you get. Keep your room locked in your absence so that nobody goes into that room in your absence. Invite guests also in your presence. The main purpose of this taking this precaution is to maintain cleanliness.
Remember me in your prayers,
