Musnad Abu Ya'la al-Mawsili 154:43

Zuhayr narrated to us, Jarir narrated to us, from Yahya ibn Sa'id, from al-Qasim ibn Muhammad, from Ibn Umar, who said: When we were with the Messenger of Allah (may Allah bless him and grant him peace) on a journey, and it was a dark night or a rainy night, the caller of the Messenger of Allah (may Allah bless him and grant him peace) would give the adhan, or his caller would proclaim: "Pray in your dwellings."
