One of the objectives behind seeking knowledge is:

{لِتَسۡتَبِینَ سَبِیلُ ٱلۡمُجۡرِمِینَ} "So the way of the wicked may become distinct." [Sūrah Al-Anʿām: 55] In other words: Understand the truth, recognise those who uphold it, and align yourself with them; identify falsehood, recognise those associated with it, and stay far from them.
