4. Muhammad ibn Yahya has narrated from Ali ibn al-Husayn in a marfu‘ manner the following: “He (the narrator) has said that abu ‘Abd Allah (a.s.), once asked, ‘What is the distance between you and Euphrates?’ I then informed him (the Imam) and he (the Imam) said, ‘Were I there near it I would go to it during both ends of the day.’”
