Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) said: Some people will remain in Hell for as long as Allah wills, then Allah, the Exalted, will have mercy on them and bring them out. These people will be the lowest in rank among the people of Paradise. They will be bathed in the spring of life. The people of Paradise will call them “the Jahannamis” (those who were in Hell). If any one of them were to go to all the people of the world, he could feed them, give them drink, and provide bedding for all of them. (The narrator says:) I think these words are also in the narration: He could arrange their marriages. Yet, the blessings he possesses would not decrease in the least.
