Chapter: A man who prays while there is a flowing river in front of him

• I said to Ishaq: "What about a man who prays while there is a river flowing with water in front of him?" He said: "If it is a river in which ships sail, he should not pray (1). If ships do not sail in it, it is easier."

1113 - Muhammad ibn al-Wazir narrated to us, he said: al-Walid ibn Muslim narrated to us, he said: I said to Abu 'Amr al-Awza'i: "Is a river a sutrah (barrier)?" He said: "Yes."

1114 - al-Walid said: Ismail informed me, from Aban, from Mujahid, from Ibn 'Umar, who said: "If you pray and there is a flowing stream in front of you through which water passes, it is a sutrah; nothing from behind the stream shall interrupt your prayer."
