What are the actions a young man should undertake to have a positive role from which the Ummah benefits, and is involvement in charitable organizations sufficient for that?

It is recommended to focus on studying the Islamic sciences, memorizing the Quran, learning the legal rulings and their proofs, acting upon what is learned, and teaching it to others. It is also necessary to utilize charitable works and aid as a means to connect people with Allah and strengthen their faith, emulating what the Christians have done in attracting people.
