What is meant by faraj [salvation]?
One important point regarding the issue of Mahdawiyyah is that in the Islamic and Shia belief systems, waiting for the arrival of Imam Mahdi has been interpreted as waiting for salvation. What does salvation mean? It means being saved. When do we usually yearn for salvation? We do so when we are in a difficult situation, and when there is a problem. When we face problems, we are in need of salvation - that is someone who can solve our problems and save us. This is an important point. The true meaning of waiting for a savior is that those who believe in Islam and the religion of the Prophet's household (a.s.) identify the problems of humans in the modern world. This is what they should actually do. They are waiting for the problems of humanity to be solved. The issue is not limited to my or your problems only. The Imam of the Time (may our souls be sacrificed for his sake) will come to solve the problems of humanity. He will come to save humanity forever. This means that those who are waiting for the arrival of Imam Mahdi are discontent about the current situation of the world - the unfair situation of the world in which many innocent people are oppressed, many are misled, and many others do not find the opportunity to worship God. Waiting for the arrival of Imam Mahdi means opposing the current situation that is prevalent in humans' life, and which has been caused due to the prevalence of ignorance and carnal desires in humans' life. This is the true meaning of waiting for the arrival of Imam Mahdi.
