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