Yahya related to me from Malik from Nafi that on a journey Abdullah ibn Umar did no more than the iqama, except for subh, when he called both the adhan and the iqama. Abdullah ibn Umar used to say, "The adhan is for an imam whom people join ."
Muwatta Malik Book 3, Hadith 12
← Previous Hadith Yahya related to me from Malik from Nafi that Abdullah ibn Umar called the adhan on a cold and windy night and included the phrase, "Do the prayer in shelter." Then he said, "The Messenger of Allah, may Allah bless him and grant him peace, used to orderthe muadhdhin to say, 'Do the prayerin shelter' when it was a cold, rainy night "

Muwatta Malik Book 3, Hadith 11 Next Hadith → Yahya related to me from Malik from Hisham ibn Urwa that his father said to him, "When you are on a journey you can, if you wish, call the adhan and the iqama, or, if you wish, the iqama and not the adhan."

Yahya said that he heard Malik say, "There is no harm in a man calling the adhan while riding."
