“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.’”
كَانَ رَسُولُ اللَّهِ ﷺ يُنَادِي مُنَادِيهِ فِي اللَّيْلَةِ الْمَطِيرَةِ أَوِ اللَّيْلَةِ الْبَارِدَةِ ذَاتِ الرِّيحِ صَلُّوا فِي رِحَالِكُمْ
Nafi' reported: Ibn Umar made the call to prayer at Dajnan (a place between Mecca and Medina). Then he announced: "Offer prayer in your dwellings:" He then narrated a tradition from the Messenger of Allah ﷺ. He used to command an announcer who made the call to prayer. He then announced: "Pray in your dwellings" on a cold or rainy night during journey. Abu Dawud said: This tradition has been narrated by Hammad b. Salamah from Ayyub and 'Ubaid Allah. In his version he added: During journey on a cold or a rainy night. (Using translation from Abū Dāʾūd 1061)
أَنَّ رَسُولَ اللهِ ﷺ كَانَ يَأْمُرُ الْمُنَادِي فَيُنَادِي بِالصَّلَاةِ ثُمَّ يُنَادِي فِي إِثْرِهَا أَنْ صَلُّوا فِي رِحَالِكُمْ فِي اللَّيْلَةِ الْبَارِدَةِ أَوِ اللَّيْلَةِ الْمَطِيرَةِ
