The Blessings and Responsibilities of Islamic Knowledge (Deen)
That is, this person is induced with the desire to learn the different masa'il of Deen. Furthermore, he understands them and practices upon them.
Rasulullah (ﷺ) said: "The person who is asked a Deeni masala and he conceals it (despite knowing the answer) will be made to wear a bridle of fire."
If anyone asks you a mas'ala and you know the answer, then do not display any laziness in giving the answer. Nor should you refuse him. Instead, explain the mas'ala to the person in a proper manner.
However, if you do not remember the masala thoroughly, do not insist on giving an immediate answer. Instead, confirm it with a learned person first and then supply the answer.
Rasulullah (ﷺ) said: "The more knowledge a person has, the greater the burden he has to bear except for the one who acts according to his knowledge."
Don't ever act contrary to a mas'ala that you know merely to satisfy your family or on account of following your desires.
