"So when she heard of their accusation, she sent for them and prepared a banquet for them; she gave each one of them a knife (to cut the foodstuff with), and she said [(to Yoosuf (Joseph)]: "Come out before them." Then, when they saw him, they exalted him (at his beauty) and (in their astonishment) cut their hands, They said: "How perfect is Allaah (or Allaah forbid)! No man is this! This is none other than a noble angel!"" [Yoosuf (12):31]

Narrated Abu Said Al-Khudri:

The Prophet said, "When the people of Paradise will enter Paradise and the people of Hell will go to Hell, Allah will order those who have had faith equal to the weight of a grain of mustard seed to be taken out from Hell. So they will be taken out but (by then) they will be blackened (charred). Then they will be put in the river of Haya' (rain) or Hayat (life) (the Narrator is in doubt as to which is the right term), and they will revive like a grain that grows near the bank of a flood channel. Don't you see that it comes out yellow and twisted" [The Book of Faith Volume 1, Book 2, Hadeeth 21]
