4. Muhammad ibn Yahya has narrated from Muhammad ibn al-ffusayn, from Ali ibn al-Hakam, from ‘Ala’ ibn Razin, from Muhammad ibn Muslim who has said the following
“I once asked one of the two Imam, ‘Alayhim al-Salam, about a man who urinates but does not touch anything, must he wash it with water? He (the Imam) said, ‘Yes, if he has experienced sexual relation.’”
