Hadith 30

Sahih Bukhari

Book 10: Call to Prayers (Adhaan)

Chapter 18

If there are many travellers, Adhan and Iqama should be pronounced, (the same is to be observed) in 'Arafat and Al-Muzdalifa too

باب الأَذَانِ لِلْمُسَافِرِ إِذَا كَانُوا جَمَاعَةً، وَالإِقَامَةِ، وَكَذَلِكَ بِعَرَفَةَ وَجَمْعٍ

On a very cold or a rainy night, the Mu'adh-dhin’s saying: As-Salatu fir-Rihal [Offer Salat (prayer) at your Ar-Rihal (homes or camps)]." ​​
وَقَوْلِ الْمُؤَذِّنِ الصَّلاَةُ فِي الرِّحَالِ‏.‏ فِي اللَّيْلَةِ الْبَارِدَةِ أَوِ الْمَطِيرَةِ
Sahih al-Bukhari 633
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.‏
`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."
