Mu'awiya bin Hadeej · The Book of Greetings

I said: Messenger of Allah, there were things we used to do in the pre-Islamic days. We used to visit Kahins, whereupon he said: Don't visit Kahins. I said: We used to take omens. He said: That is a sort of personal whim of yours, so let it not prevent you (from doing a thing).

I said: Among us there are men who draw lines and thus make divination. What about this? Thereupon he (the Holy Prophet) said: There was a Prophet who drew lines, so whose lines agree with his line for him it is allowable.
