"A man of Thaqif told us that he heard the caller of the Messenger of Allah ﷺ on a rainy night during a journey saying: 'Hayya 'ala as-salah, Hayya 'ala al'falah, sallu fi rihalikum (Come to prayer, come to prosperity, pray in your dwellings).'" (Using translation from Nasāʾī 653)  

أَنَّهُ سَمِعَ مُنَادِيَ النَّبِيِّ ﷺ يَعْنِي فِي لَيْلَةٍ مَطِيرَةٍ فِي السَّفَرِ يَقُولُ «حَيَّ عَلَى الصَّلَاةِ حَيَّ عَلَى الْفَلَاحِ صَلُّوا فِي رِحَالِكُمْ»  

Pray in your dwellings; and then said: When it was a cold, rainy night, the Messenger of Allah ﷺ used to command the Mu'adhdhin to say" Pray in your dwellings." (Using translation from Muslim 697a)  

أَلَا صَلُّوا فِي الرِّحَالِ فَإِنَّ رَسُولَ اللهِ ﷺ كَانَ يَأْمُرُ الْمُؤَذِّنَ إِذَا كَانَتْ لَيْلَةٌ بَارِدَةً ذَاتَ مَطَرٍ يَقُولُ «أَلَا صَلُّوا فِي الرِّحَالِ»
