Nafi' said: Ibn Umar made the call to prayer at Dajnan (a place between Mecca and Medina), on a cold and windy night. He added the words at the end of the call: "Lo! pray in your dwellings. Lo! pray in the dwellings." He then said: The Messenger of Allah ﷺ used to command the mu'adhdhin to announce, "Lo! pray in your dwellings." on a cold or rainy night during journey.
أَنَّهُ نَادَى بِالصَّلاَةِ بِضَجْنَانَ فِي لَيْلَةٍ ذَاتِ بَرْدٍ وَرِيحٍ فَقَالَ فِي آخِرِ نِدَائِهِ أَلاَ صَلُّوا فِي رِحَالِكُمْ أَلاَ صَلُّوا فِي الرِّحَالِ ثُمَّ قَالَ إِنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَأْمُرُ الْمُؤَذِّنَ إِذَا كَانَتْ لَيْلَةٌ بَارِدَةٌ أَوْ ذَاتُ مَطَرٍ فِي سَفَرٍ يَقُولُ أَلاَ صَلُّوا فِي رِحَالِكُمْ
