Mu'awiya b. al-Hakam as-Sulami reported: 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).
This hadith teaches us that we should be careful when relying on superstitious beliefs such as visiting kahins or taking omens when making decisions about our lives; instead we should use our own judgement and rely on sound evidence before making important choices in life. It also reminds us that it is okay for us to have our own personal whims but we should be aware of how much influence they have over our decision making process so that we do not end up regretting them later on down the line.
