Sahih al-Bukhari 633
Sahih al-Bukhari · Book 10: Call to Prayers (Adhaan) · If there are many travellers, Adhan and Iqama should be pronounced, (the same is to be observed) in 'Arafat and Al-Muzdalifa too
Narrated `Aun bin Abi Juhaifa:
حَدَّثَنَا إِسْحَاقُ ، قَالَ أَخْبَرَنَا جَعْفَرُ بْنُ عَوْنٍ ، قَالَ حَدَّثَنَا أَبُو الْعُمَيْسِ ، عَنْ عَوْنِ بْنِ أَبِي جُحَيْفَةَ ، عَنْ أَبِيهِ ، قَالَ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم بِالأَبْطَحِ فَجَاءَهُ بِلاَلٌ فَآذَنَهُ بِالصَّلاَةِ، ثُمَّ خَرَجَ بِلاَلٌ بِالْعَنَزَةِ حَتَّى رَكَزَهَا بَيْنَ يَدَىْ رَسُولِ اللَّهِ صلى الله عليه وسلم بِالأَبْطَحِ وَأَقَامَ الصَّلاَةَ.
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."
