It was narrated that Ibn ‘Umar said:
“On rainy nights or on cold windy nights, the Messenger of Allah ﷺ would summon his announcer to call out: ‘Perform your prayer at your camps.’”

حَدَّثَنَا مُحَمَّدُ بْنُ الصَّبَّاحِ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ أَيُّوبَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ كَانَ رَسُولُ اللَّهِ ـ ﷺ ـ يُنَادِي مُنَادِيهِ فِي اللَّيْلَةِ الْمَطِيرَةِ أَوِ اللَّيْلَةِ الْبَارِدَةِ ذَاتِ الرِّيحِ " صَلُّوا فِي رِحَالِكُمْ " .
