Men attending university

We will not advise any person who is committed to his Deen to study in such an environment. As for a person who is not a committed to his Deen, then though the appropriate thing for him also is that he should save himself from such an environment, however if he feels it difficult to refrain, then he should continue to make istighfaar and seek Allah Ta'ala's forgiveness for remaining in such an environment.

And Allah Ta'ala (الله تعالى) knows best.
