(18) باب الأَذَانِ لِلْمُسَافِرِ إِذَا كَانُوا جَمَاعَةً، وَالإِقَامَةِ، وَكَذَلِكَ بِعَرَفَةَ وَجَمْعٍ
Narrated `Aun bin Abi Juhaifa:
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."
