A common technique against black magic is to drink ruqyah water. Ruqyah water is water over which Quran is recited over. But oftern it is easier to use sheets with Quran printed on them with edible ink rather than recite and blow on the water.
see link for example:
Now you can buy sheets that have entire Quran or with selected verses.
But what my question is: Does anyone know where I can order tailor made sheets? That is sheets with Quran on that I want, rather than pre-made ones. I've checked the internet but could not find anything.
