The fourth life extends from the time when a person leaves his grave for the Resurrection and Gathering, until the moment that mankind will enter Garden or Fire.

"All this is because Allah, He is the Truth, and because He resurrects the dead, and because He has power over everything, the Hour shall surely come to pass - in this there is no doubt - and Allah shall surely resurrect those that are in graves." [22:6-7]

Abu Razan al-Uqayli, may God be pleased with him, said: 'I once asked, "O Messenger of Allah! How does Allah originate creation, and what is the sign of it in his creation?" 

The Messenger (peace and blessings be upon him) replied, "Have you ever passed your people's valley when it was barren, and then crossed it again when it was swaying with greenery?" I said, "Indeed, I have. The he said, "That is His sign in His Creation." 

On the day when the earth shall be changed to other than the earth, and the heavens, and they will come forth before Allah, the One, the Invincible." [14:48]

When Allah wishes to resurrect mankind, the sky will pour down a type of rain. This rain will cause the things that were buried to come back alive, the way that crops grow. Then Allah commands Isra'fil to blow the Horn for Resurrection. The spirits will return to their bodies and be brought back to life. 

The Prophet Muhammad, peace and blessings be upon him said, "People shall be gathered more hungry than they have ever been, more thirsty than they have ever been, more exposed than they have ever been, and more exhausted than they have ever been.

Those who had given food for Allah's sake will be fed by Him, those who had given drink will be given drink by Him, those who had given clothes will be clothed by Him, those who had acted for Allah's sake will be Protected by Him." 

All people will be gathered in one place. At the time, people will see their deeds appearing before them. Good deeds will accompany them and comfort them. Wicked ones will reproach them and make them feel desolate. People will take the form of their reality. 

Each person will be accompanied by recording angels who had recorded all of his actions in his worldly life. 

There will be three groups of people, described in hadith: those who will ride, those who will walk on their feet,  and those who will walk on their faces. For, 'the One who made them walk on their feet is capable of making them walk on their faces.'

The Prophet, peace be upon him said, "People will be gathered in a shining white land, and resembling pure flour, where there will be signs for no-one."

This is the 'standing-place' of the Day of Rising. all creatures will be assembled: jinn, men, devils, cattle, wild beasts, and predators. The the angels will surround them all and no one can escape. 

The Balance and the Bridge 

At this time good and bad deeds will be weighed against each other. For those whose good deeds are heavier on the scale, a bridge will be in front of them. The bridge is sharp and narrow, and people can only cross it with their deeds. Those with strong faith with cross it fast and light light a feather, and those with many bad deeds the bridge will be slippery and they will crawl to cross it.
