The Messenger of God Intercedes for the Faithful
'Then shall the messenger of God say: "O Lord, there are of the faithful who have been in hell seventy thousand years. Where, O Lord, is thy mercy? I pray thee, Lord, to free them from those bitter punishments."'
'Then shall God command the four favourite angels of God that they go to hell and take out every one that hath the faith of his messenger, and lead him into paradise. And this they shall do.'
'And such shall be the advantage of the faith of God\'s messenger, that those that shall have believed in him, even though they have not done any good works, seeing they died in this faith, shall go into paradise after the punishment of which I have spoken.'
'Then the Messenger of God will say, "O Lord, some of the faithful have been in hell for seventy thousand years. Where, O Lord, is your mercy? I pray you, Lord, free them from those bitter punishments."'
'Then God will command his four favored angels to go to hell, take out everyone who has the faith of his Messenger, and lead them into paradise. And they will do so.'
'Such will be the benefit of faith in God's Messenger that those who believed in him, even though they performed no good works, will enter paradise after the punishment of which I have spoken, since they died in that faith.'
