Narrated Nafi`: Once in a cold night, Ibn `Umar pronounced the Adhan for the prayer at Dajnan (the name of a mountain) and then said, "Pray at your homes", and informed us that Allah's Messenger (ﷺ) used to tell the Mu'adh-dhin to pronounce Adhan and say, "Pray at your homes" at the end of the Adhan on a rainy or a very cold night during the journey."
