When is taking knowledge from a scholar impermissible? Or when does an individual not take knowledge from a scholar?
First of all, if this individual is not really a scholar first and foremost, or if he’s just acting like he’s a scholar, then (knowledge) it is not to be taken from him. For an individual does not take knowledge except from those who bear the knowledge and those who are the carriers of knowledge. Because how many people claim that they are the carriers of knowledge or bear knowledge, but in reality the opposite is true.
So first and foremost, this individual needs to prove that he’s knowledgeable and strives to gain that knowledge and or he’s a Mujtahid.
Second of all, it needs to be confirmed that this individual is upon the Sunnah. For (knowledge) is not taken from an innovator. No type of knowledge or from the sciences.
Third, this individual needs to be trustworthy (and) truthful. Because knowledge is not taken from an individual who is a liar.
And fourth, this individual needs to be ‘adl, upon piety and uprightness. Because knowledge is not taken from a sinner.
