BUKHARI 632:
from Nāfiʿ —
Once in a cold night, Ibn ʿUmar pronounced the Adhan for the prayer at Dajnan (the name of a mountain) and then said, "Pray at your homes", and informed us that Messenger of Allah 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."
البخاري ٦٣٢:
عن نافع —
أَذَّنَ ابْنُ عُمَرَ فِي لَيْلَةٍ بَارِدَةٍ بِضَجْنَانَ ثُمَّ قَالَ صَلُّوا فِي رِحَالِكُمْ فَأَخْبَرَنَا أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَأْمُرُ مُؤَذِّنًا يُؤَذِّنُ ثُمَّ يَقُولُ عَلَى إِثْرِهِ أَلاَ صَلُّوا فِي الرِّحَالِ فِي اللَّيْلَةِ الْبَارِدَةِ أَوِ الْمَطِيرَةِ فِي السَّفَرِ
