With regards to people seeking knowledge from the youngsters at the expense of seeking it from the senior scholars, `Abdus Salaam ibn Burjis (d.1425AH) rahimahullaah comments:
And indeed the phenomenon of taking knowledge from the younger ones amongst the students of knowledge has become widespread in this era.
And in reality this phenomenon is a chronic disease, an enduring sickness, preventing the (true) student from what he intends and something by which he twists away from the correct path which would lead to knowledge.
And that is because taking knowledge from the younger people – those whose feet have not become firmly grounded in knowledge and whose beards have not become white in it (seeking knowledge), despite the presence of a person who is greater than them in age and one whose feet are more firmly grounded – then this weakens the foundation of the beginner and prevents him from taking benefit from the knowledge of the senior scholars, and from acquiring their manners which knowledge and time have made good – and other than that from the justifications that are suggested by the narration of ibn Mas`ood radi Allaahu `anhu when he said:
“The people will not cease to be upon good as long as they take knowledge from their senior ones and from their trustworthy ones and from their scholars.
So if they take it from their younger ones and their evil ones, they will be destroyed.”
