p35.0 LEARNING SACRED KNOWLEDGE FOR THE SAKE OF THIS WORLD, OR CONCEALING IT
(A: Learning Sacred Knowledge for the sake of this world means that if not for this-worldly reasons, a person would not have bothered to learn (dis: a3.I).)
p35.1 Allah Most High says:
(1) “Only the knowledgeable of His slaves fear Allah” (Koran 35:28).
(2) “Those who conceal what Allah has revealed of the Book and purchase a trifling price thereby, these but fill their bellies with hellfire” (Koran 2:174).
(3) “And Allah made a covenant with those given the Book to explain it to people and not keep it from them. But they flung it behind their backs” (Koran 3:187).
p35.2 The Prophet (Allah bless him and give him peace) said,
“Anyone who seeks Sacred Knowledge to vie with scholars, argue with fools, or win people’s hearts will go to hell.”
p35.3 Hilal ibn aI-‘Ala’ said, “Seeking Sacred Knowledge is arduous, learning it is harder than seeking it, applying it is harder than learning it, and remaining safe from it is even harder than applying it.”
