Imam Bukhari narrates: Musaddad narrated to us, he said: Yahya informed us from Ubaidullah bin Umar, he said: Nafi' narrated to me, he said that
Ibn Umar, may Allāh be pleased with them both, gave the Adhan on a cold night in Dajnan, then said: Pray in your homes. Then he informed us that the Messenger of Allāh ﷺ used to command a mu'adhdhin to give the Adhan, he would give the Adhan, then after the Adhan he would say: Listen! On a cold night or a rainy night while travelling, pray in your homes.
حَدَّثَنَا مُسَدَّدٌ، قَالَ أَخْبَرَنَا يَحْيَى، عَنْ عُبَيْدِ اللَّهِ بْنِ عُمَرَ، قَالَ حَدَّثَنِي نَافِعٌ، قَالَ أَذَّنَ ابْنُ عُمَرَ فِي لَيْلَةٍ بَارِدَةٍ بِضَجْنَانَ ثُمَّ قَالَ صَلُّوا فِي رِحَالِكُمْ، فَأَخْبَرَنَا أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يَأْمُرُ مُؤَذِّنًا يُؤَذِّنُ، ثُمَّ يَقُولُ عَلَى إِثْرِهِ، أَلاَ صَلُّوا فِي الرِّحَالِ. فِي اللَّيْلَةِ الْبَارِدَةِ أَوِ الْمَطِيرَةِ فِي السَّفَرِ.
