The rain was falling on the day when the Battle of Hunayn took place. The Prophet ﷺ, therefore, commanded that the people should offer their prayer in their camps. (Using translation from Abū Dāʾūd 1057)

أَنَّ يَوْمَ حُنَيْنٍ كَانَ يَوْمًا مَطِيرًا فَأَمَرَ النَّ‍بِيُّ ﷺ مُنَادِيَهُ فَنَادَى إِنَّ الصَّلَاةَ فِي الرِّحَالِ

[Machine] From his father, that they were with the Messenger of Allah ﷺ on the day of Hunayn, and then rain fell on them. So their announcer called to them, "Pray in your saddles."

عَنْ أَبِيهِ أَنَّهُمْ كَانُوا مَعَ رَسُولِ اللهِ ﷺ يَوْمَ حُنَيْنٍ فَأَصَابَهُمْ مَطَرٌ فَنَادَى مُنَادِيَهُ أَنْ صَلُّوا فِي رِحَالِكُمْ

"We were with the Messenger of Allah ﷺ in Hunain and it rained. The caller of the Messenger of Allah ﷺ called out, telling us: 'Pray where you are."' (Using translation from Nasāʾī 854)

كُنَّا مَعَ رَسُولِ اللَّهِ ﷺ زَمَنَ الْحُدَيْبِيَةِ وَأَصَابَنَا مَطَرٌ لَمْ يَبُلَّ أَسَافِلَ نِعَالِنَا فَنَادَى مُنَادِي رَسُولِ اللَّهِ ﷺ أَنْ «صَلُّوا فِي رِحَالِكُمْ»

[Machine] We were hit by a rain in Hunayn, then a caller called out the Messenger of Allah ﷺ, "Pray while on the mounts."

أَصَابَنَا مَطَرٍ بِحُنَيْنٍ فَنَادَى مُنَادِي رَسُولِ اللَّهِ ﷺ «أَنْ صَلُّوا فِي الرِّحَالِ»

[Machine] We were with the Messenger of Allah ﷺ on a rainy day when he commanded a caller to announce, "Prayer is to be performed in travel."

كُنَّا مَعَ رَسُولِ اللهِ ﷺ فِي يَوْمٍ مَطِيرٍ فَأَمَرَ مُنَادِيًا فَنَادَى «إِنَّ الصَّلَاةَ فِي الرِّحَالِ»

[Machine] I witnessed with the Messenger of Allah ﷺ the battle of Hunayn, and we were suddenly caught in a heavy rainfall. Then a caller called out on behalf of the Messenger of Allah ﷺ , "Whoever wishes to pray in his place, let him pray."

شَهِدْتُ مَعَ رَسُولِ اللهِ ﷺ حُنَيْنًا فَأَصَابَنَا بَغْشٌ يَعْنِي مَطَرًا فَنَادَى مُنَادِي رَسُولِ اللهِ ﷺ «مَنْ شَاءَ أَنْ يُصَلِّيَ فِي رَحْلِهِ فَلْيُصَلِّ»

"We were with the Messenger of Allah ﷺ in Hunain and it rained. The caller of the Messenger of Allah ﷺ called out, telling us: 'Pray where you are."' (Using translation from Nasāʾī 854)

«كُنَّا مَعَ رَسُولِ اللهِ ﷺ بِحُنَيْنٍ فَأَصَابَنَا مَطَرٌ فَنَادَى مُنَادِي رَسُولِ اللهِ ﷺ أَنْ صَلَّوْا فِي رِحَالِكُمْ»

[Machine] We were struck by rain on the day of Hudaybiyah that did not wet the soles of our shoes. Then the caller of the Prophet ﷺ called out to us to pray in our camel saddles.

أَصَابَنَا يَوْمَ الْحُدَيْبِيَةِ مَطَرٌ لَمْ تُبَلَّ أَسَافِلُ نِعَالِنَا فَنَادَى يَعْنِي مُنَادِيَ النَّبِيِّ ﷺ أَنْ صَلُّوا فِي رِحَالِكُمْ

[Machine] We were with the Messenger of Allah ﷺ when a sudden rain shower came upon us. At that moment, the caller of the Messenger of Allah ﷺ called out, saying, "Whoever wants to pray on their ride should do so."

كُنَّا مَعَ رَسُولِ اللهِ ﷺ فَأَصَابَنَا بُغَيْشٌ مِنْ مَطَرٍ فَنَادَى مُنَادِي رَسُولِ اللهِ ﷺ وَنَحْنُ فِي سَفَرٍ مَنْ شَاءَ أَنْ يُصَلِّيَ فِي رَحْلِهِ فَلْيَفْعَلْ
