Mukhtasar Bukhari

Narrated by Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) from the Noble Prophet (peace and blessings of Allah be upon him) that he (peace be upon him) said: "(When) the people of Paradise will have entered Paradise and the people of Hell will have entered Hell, then after that Allah Almighty will say (to the angels): 'Whoever has in his heart even a mustard seed's weight of faith, take him out (from Hell).' So they will be taken out from Hell, and they will have become blackened (by burning). Then they will be thrown into the stream of Hayat (rain) or the stream of Life." These words of doubt are from Imam Malik (who is one of the narrators of the hadith). "Then they will become fresh as a seed grows fresh in the flow of water. (O person!) Have you not seen that it comes out yellow and intertwined?"
