Yahya related to me from Malik from Nafi from Abdullah ibn Umarthat the Messenger of Allah, may Allah bless him and grant him peace,made his camel kneel down at al-Batha, which is at Dhu'l-Hulayfa, andprayed there. Nafi said, "Abdullah ibn Umar used to do that."Malik said, "No-one should go past al-Muarras when he is returningfrom hajj without praying there. If he passes it at a time when prayeris not permissible he should stay there until prayer is permissibleand then pray whatever he feels is appropriate. (This is) because Ihave heard that the Messenger of Allah, may Allah bless him and granthim peace, stopped there to rest, and that Abdullah ibn Umar stoppedhis camel there also."
