Hadith 26

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 629
حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنِ الْمُهَاجِرِ أَبِي الْحَسَنِ، عَنْ زَيْدِ بْنِ وَهْبٍ، عَنْ أَبِي ذَرٍّ، قَالَ كُنَّا مَعَ النَّبِيِّ صلى الله عليه وسلم فِي سَفَرٍ فَأَرَادَ الْمُؤَذِّنُ أَنْ يُؤَذِّنَ فَقَالَ لَهُ ‏"‏ أَبْرِدْ ‏"‏‏.‏ ثُمَّ أَرَادَ أَنْ يُؤَذِّنَ فَقَالَ لَهُ ‏"‏ أَبْرِدْ ‏"‏‏.‏ ثُمَّ أَرَادَ أَنْ يُؤَذِّنَ‏.‏ فَقَالَ لَهُ ‏"‏ أَبْرِدْ ‏"‏‏.‏ حَتَّى سَاوَى الظِّلُّ التُّلُولَ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏{‏إِنَّ شِدَّةَ الْحَرِّ مِنْ فَيْحِ جَهَنَّمَ‏}‏
Abu Dhar:

We were in the company of the Prophet (ﷺ) on a journey and the Mu'adh-dhin wanted to pronounce the Adhan for the (Zuhr) prayer. The Prophet (ﷺ) said to him, "Let it become cooler." Then he again wanted to pronounce the Adhan but the Prophet; said to him, "Let it become cooler." The Mu'adh-dhin again wanted to pronounce the Adhan for the prayer but the Prophet (ﷺ) said, "Let it become cooler," till the shadows of the hillocks become equal to their sizes. The Prophet (ﷺ) added, "The severity of the heat is from the raging of Hell."
