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. (Using translation from Abū Dāʾūd 1062)
فِي آخِرِ نِدَائِهِ أَلَا صَلُّوا فِي رِحَالِكُمْ أَلَا صَلُّوا فِي رِحَالِكُمْ أَلَا صَلُّوا فِي الرِّحَالِ فَإِنَّ رَسُولَ اللهِ ﷺ كَانَ يَأْمُرُ الْمُؤَذِّنَ إِذَا كَانَتْ لَيْلَةٌ بَارِدَةٌ أَوْ ذَاتُ مَطَرٍ أَوْ ذَاتُ رِيحٍ فِي السَّفَرِ أَلَا صَلُّوا فِي الرِّحَالِ
