Is stopping the study of Islamic sciences a sin, due to fear of not being able to commit and [fear of] the demands of the surrounding environment?

The path of seeking knowledge is arduous, long, and full of obstacles, yet its outcome is praiseworthy. Whoever treads it becomes one of God's most beloved saints. This knowledge is inherited from every righteous successor who refutes the distortions of the ignorant. Therefore, patience, perseverance, resilience, and avoiding weariness are essential for the seeker of knowledge to become one of the best and most knowledgeable people concerning God. Beneficial knowledge rectifies bad manners, and among the aiding factors for this are the companionship of humble and forbearing people, and supplication. An example of this is the supplication of the Prophet, peace and blessings be upon him: "Guide me to the best of manners, for none guides to the best of them except You, and turn away from me the worst of them, for none turns away from me the worst of them except You." One must beware of the whispers of Satan that discourage seeking knowledge. Regarding the ruling on abandoning the pursuit of knowledge: if the knowledge is something that must be learned to correct one's creed, worship, and dealings, then abandoning it is a sin.
