"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).'"  

أَنَّهُ سَمِعَ مُنَادِيَ النَّبِيِّ ﷺ يَعْنِي فِي لَيْلَةٍ مَطِيرَةٍ فِي السَّفَرِ يَقُولُ حَىَّ عَلَى الصَّلاَةِ حَىَّ عَلَى الْفَلاَحِ صَلُّوا فِي رِحَالِكُمْ  

"Pray where you are, for the Prophet ﷺused to order the Mu'adhdhin, if it was a cold and rainy night, to say: 'Pray in your dwellings.'"  

أَلاَ صَلُّوا فِي الرِّحَالِ فَإِنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَأْمُرُ الْمُؤَذِّنَ إِذَا كَانَتْ لَيْلَةٌ بَارِدَةٌ ذَاتُ مَطَرٍ يَقُولُ أَلاَ صَلُّوا فِي الرِّحَالِ
