In The Name of Allah, The Most Merciful, The Bestower of Mercy.

One of the negative tendencies exhibited by those who claim that certain actions are only “Makruh” and not “Haram” is their habit of seeking out favorable Fatwas or exploiting the errors made by scholars on specific matters that align with their personal desires. For instance, when they wish to have a prohibited haircut or engage in similar activities, they often justify it by saying, “We or someone on our behalf asked the Shaikh, and he said it is permissible.”

Al-Allaamah Saalih al-Fawzaan was asked: What is the meaning of the principle, “The truth is not known by way of men, rather men are known by way of the truth?”

Answer: Its meaning is that we do not simply blindly follow anyone, as it is possible for someone to be blindly followed based on error. It is possible for the Mujtahid to be mistaken, as well as the one who makes a statement or holds an opinion, so we do not accept their statement or opinion simply because of their status or reputation. We do not say, “This is truth because so-and-so said it, and he is a knowledgeable scholar or a pious person.” We do not say this because even scholars are not infallible and they can make mistakes. Therefore, we recognise individuals based on their adherence to the truth – those who possess knowledge and rely on evidence. Those who do not give importance to evidence are not scholars, they lack understanding and knowledge, and their statements are not immediately accepted. It is essential that evidence is presented, so if the evidence supports what they say or hold, then it is considered truth. However, if they contradict the evidence, then their statement or opinion is rejected. If someone is a Mujtahid and makes a mistake, they are rewarded for their effort. But if they intentionally cling to error, they have committed a sin. [Paraphrased: Refer to video here: https://video.link/w/9famb%5D
