Sahih al-Bukhari Book 10, Hadith 30
My father said, "I saw Allah's Messenger (ﷺ) at a place called Al-Abtah. Bilal came and informed him about
the prayer and then came out with a short spear (or stick) and planted it in front of Allah's Messenger (ﷺ) at
Al-Abtah and pronounced the Iqama."
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."
My father said, "I saw Bilal turning his face from side to side while pronouncing the Adhan for the prayer."
