Hazrat Mahdi (as) will free the world from evils and oppressive systems, and will cause love and peace to reign among people

The Commander of the Faithful (ra) gives glad tiding in his sermon that the world shall be purified and reformed from the cursed ones, and the war against the tyrant shall last for eight months after than love and peace shall prevail. (Selected Supplications from al-Sahifah al-Mahdiyah, Sayyid Murtadha Mujtahidi Sistani, p. 69)

As a result of Hazrat Mahdi (as)’s intellectual struggle against Darwinism and materialism, which is one of his three great duties, vices that run contrary to human nature, such as cruelty, ruthlessness and lovelessness, the products of such philosophies, will all come to an end. Movements that prevent countries and people living by religious moral values, loving one another, feeling compassion, getting on with one another and treating one another in compliance with religious moral values will cease. These philosophies and their exponents, that encourage people to lead degenerate lives, with no faith in Allah and that have lost all spiritual values, will be intellectually neutralized by way of Hazrat Mahdi (as). There will be a climate of great peace and love across the world, and a profound spirit of friendship, mutual aid, unity and alliance will prevail among countries and individuals.
