Narrated by Muhammad ibn Ali ibn Mahbub, from Ali ibn al-Sindi, from Ibn Abi Umayr, from Jamil ibn Darraj, who said: I asked Abu Abdullah عليه السلام about a man who becomes junub but forgets to urinate before performing ghusl, and afterward sees something after the ghusl. Should he perform ghusl again? Imam عليه السلام said: "No, it has already been squeezed out and descended from the passageways."
