I am not experienced buzurg or something. So I am not here to write what I think e.t.c but I will give you a gift. Which is the bayan of moulana yunus patel (ra), someone wrote it down : http://yunuspatel.co.za/downloads/Tafweez.pdf Hadhrat colonel's advice are very authentic and great. Mashallah, it would be best also to follow what he writes.
