Prayer (Kitab Al-Salat): Details of Commencing Prayer

Dawud :: Book 3 : Hadith 1057

Narrated Abdullah ibn Umar:

Nafi' said: Ibn Umar made the call to prayer at Dajnan (a place between Mecca and Medina), on a cold and windy night. He added the words at the end of the call: "Lo! pray in your dwellings. Lo! pray in the dwellings." He then said: The Apostle of Allah (peace_be_upon_him) used to command the mu'adhdhin to announce, "Lo! pray in your dwellings." on a cold or rainy night during journey.
