How can I support Islam?

The triumph of Islam is achieved through righteousness and reform. Righteousness is attained through beneficial knowledge and good deeds, while reform is achieved through calling to Allah, enjoining good and forbidding evil, and cooperating in piety and righteousness. Whoever adheres to these matters and perseveres in them has truly supported Islam, which is what is required by His (Allah's) saying, the Most High: "By the Aṣr (Time). Indeed, mankind is in loss, Except for those who have believed and done righteous deeds and advised each other to truth and advised each other to patience." This verse brings together four qualities that save a person from loss: faith, righteous deeds, advising one another to truth, and advising one another to patience. The first two are for the perfection of the individual himself, and the latter two are for the perfection of others.
