"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»
