Sahih Muslim 184b

Abu Bakr ibn Abi Shayba narrated to us: ‘Affan narrated to us: Wuhaib narrated to us. Hajjaj ibn al-Sha‘ir narrated to us: ‘Amr ibn ‘Awn narrated to us: Khalid informed us. Both narrated from ‘Amr ibn Yahya, through this chain. They said: ‘They will be cast into a river called the River of Life,’ and neither of them expressed doubt about this. Khalid’s narration says, ‘as debris grows at the edge of a torrent,’ while Wuhaib’s narration says, ‘as a seed grows in the muddy earth or sediment carried by a torrent.’
