All religions, be it divine or otherwise, believe in the savior of the world and urge their followers to pray for his emergence.
Faith in a savior makes the tough conditions of life tolerable and helps people maintain hope in better life conditions.

Common Beliefs
In Zoroastrianism, the savior is referred to as Susyant and in Christianity and Judaism it is referred to as Masih (Jesus Christ) and Mashih respectively. In Shiism, the savior is Imam Mahdi (May God Hasten His Reappearance).

Muslims celebrate the birth anniversary of Imam Mahdi (MGHHR) on 15th ShaÕban, which coincides with Aug. 17 this year, with special ceremonies, banners and lighting.

The victory of virtue over vice, achievement of sustainable peace, destruction of oppressors and prevalence of justice in all facets of life are some of the common beliefs about the savior in divine religions.
However, the views of Shiites in this regard are rather different. Shiites believe Imam Mahdi (MGHHR) is alive and will reappear when God commands.


Differences
Judaism: Jews have always been waiting for the emergence of a savior to revive their glory during the eras of prophets David and Soloman. Jews believe Mashih will rule over the world and rescue Jews from misery and oppression. They believe that their savior is the son of Jacob and one of the antecedents of David.
Christianity: The Bible mentions that Jesus Christ will reappear to rule over the world. They believe Jesus will usher in an era of peace and justice, and judge the performance of the people.
In Christian literature, paintings show Jesus descending from the sky atop a white horse along with his army to rule over the vice-filled world as the king of kings for 1,000 years.
Zoroastrianism: Zoroastrians actually await three saviors, each of which will emerge within a span of 1,000 years. They believe that at the end of time, three sons from the lineage of Zoroaster will all be called Susyant to save the world.
Buddhism: Buddhists believe the savior is Mitraya. They consider him to be the fifth Buddha and among the last Buddhas on Earth.
Hinduism: Hindus believe that the savior Kalki will emerge. They attach credence to the idea that Kalki emerges when all facets of social and spiritual life are on the verge of destruction.
Sunnis: Sunnis believe in the emergence of a savior, but they believe that the savior has not yet been born.

Savior in Shiism
Over 100 verses of the holy Qur’an mention the savior who will rescue all the people of the world. They state that the savior will fill the world with peace and justice, and make the oppressed rulers of the world.
On that day, geographical borders will no longer be a consideration, as all countries will become one unified territory. Shiites believe that upon the reappearance of Imam Mahdi (MGHHR), all oppressors of the world, irrespective of their power, will be defeated. This belief of Shiites in the savior has made them optimistic about the future. For the same reason, no matter how much the enemies pressure Shiites, they never lose hope and never abandon their beliefs.
Shiites know that God’s promise made in the holy Qur’an will be fulfilled one day.
Lineage
Imam Mahdi (MGHHR) was born in Samarra, Iraq, in 256 (AH) to the 11th infallible Imam from the infallible household of Prophet Muhammad (PBUH), Imam Hassan Askari (AS) and Narges Khatoon.
He is the savior of the world who will make himself known at God’s command when the conditions are ripe.
Many western thinkers endorse the concept of the reappearance of Imam Mahdi (MGHHR). The distinguished British philosopher George Bernard Shaw said he respected Islam and Prophet Muhammad’s (AS) religion which, he predicted, would be accepted by Europe and rescue the world.
The famous French expert on Iranian Studies, Henry Corbin, was among Europeans who studied the issue of the reappearance of Imam Mahdi (MGHHR) in depth.
In his book ’History of Islamic Philosophy’, he relates the statement of Prophet Muhammad (AS) that even if one day remains to the end of the world, God will make that day so long that a man who is one of my progenies will emerge to fill the world with justice.
Shiism maintains that when the world is full of oppression and corruption, and when the flames of war are everywhere, Imam Mahdi (MGHHR) will reappear.
Therefore, the greatest wish of Shiites is the reappearance of Imam Mahdi (MGHHR).

People who’ve exchanged wedding vows tend to be healthier than their single, divorced or widowed peers, but new research shows that health gap may be narrowing.
Interviews with today’s never-married men suggest they are healthier than never-married guys were three decades ago, researchers say.
“One of the most-often documented facts is that married people are healthier than non-married people, but the difference between married and unmarried people has changed over the past few decades,“ said the study’s lead author, Hui Liu, an assistant professor and sociologist at Michigan State University in East Lansing.
The findings are in the September issue of the Journal of Health and Social Behavior.
Liu said there are two theories as to why married people report better health. One is that being married gives you more access to social support and economic resources. The other is that being divorced or widowed hurts health.
“In general, marriage tends to make people healthier, happier and richer, and that’s especially true for men,“ said Scott Wetzler, vice chairman of psychiatry and behavioral science, and head of the “Supporting Healthy Marriage“ program at Montefiore Medical Center in New York City.
But because trends in marriage have changed so dramatically over the past few decades, with more people opting not to marry or marrying at later ages, Liu wanted to assess what, if any, effects these changes might have on physical health.
To analyze these trends, Liu and her colleague, Debra Umberson, reviewed 32 years of data on more than one million Americans from the National Health Interview Survey. Study participants were between the ages of 25 and 80. Health status was self-reported in the survey.
The researchers found that the self-reported health status of never-married adults increased significantly over time. At the same time, the self-reported health status of married women also increased, so the gap between married and never-married women’s health stayed about the same. However, never-married men narrowed the health gap between themselves and married men.
“An important potential reason is that never-married men have greater access to social support now than they did in the past. It used to be that having a spouse was important for social support and a social network,“ explained Liu.
The researchers also found that self-reported health improved for nearly all American blacks, except for those who had been widowed.
People who had been married in the past, including those widowed or divorced, reported declines in their overall health status, according to the study.
“If you get married and then divorced, that will hurt your health,“ said Liu.
“This study provides confirmation that marriage does tend to make people healthier. They didn’t look at the quality of an individual marriage, but that being married is more likely overall to make you happier than not being married,“ said Wetzler.
