What is the ruling on a student's refusal to give her classmates homework and take-home exams, given her aversion to doing so, and is this considered hoarding knowledge or hypocrisy?

The questioner should advise her colleagues in a friendly manner that copying exam answers without effort is considered cheating, which the Prophet, peace and blessings be upon him, forbade when he said: "Whoever cheats is not one of us." She must prevent it because it constitutes cooperation in sin and aggression, in accordance with the Almighty's saying: "And do not cooperate in sin and aggression." On the other hand, she should help them with revision and explain what is difficult for them, as this is cooperation in righteousness and piety, as Allah Almighty commanded: "And cooperate in righteousness and piety."
