It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him); he said: I heard the Messenger of Allah (peace and blessings be upon him) saying: "The Sirat will be placed over the back of Hell, with thorns on it like the thorns of the sa'dan (a thorny plant). Then people will pass over it: some will be saved safe and sound, some will be saved after being wounded, and some will fall headlong into it and be held captive. Then when Allah Almighty has finished the judgements between the servants, the believers will look for people who in the world used to pray, give zakah, fast, perform Hajj and do jihad as they did. They will say: O our Lord, some of Your servants who were with us in the world, who prayed as we prayed, gave zakah as we gave, fasted as we fasted, performed Hajj and did jihad, we do not see them! Allah Almighty will say: Go, go to Hell, and whoever of them you find in it, bring him out. So they will find them in a state where the Fire has seized them according to their deeds. Of them the Fire will have seized one up to his feet, another up to his knees, another up to his waist, another up to his chest and another up to his neck, but it will not have covered the faces. They will bring them out, and they will be thrown into the Water of Life (Ma' al-Hayat)." It was asked: O Prophet of Allah, what is the Water of Life? He (peace and blessings be upon him) said: "The bathing water of the people of Paradise. They will sprout fresh in it just as a plant sprouts in the debris carried by a flood. Then the prophets will intercede for everyone who used to bear witness with sincerity to 'La ilaha illallah' (There is no true god except Allah), and they will bring them out of it. Then Allah Almighty will show tender compassion with His mercy to those in Hell, and He will not leave in it any servant in whose heart there is even an atom's weight of faith, but will bring him out of it." This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.
