كتاب إقامة الصلاة والسنة فيها
(35) Chapter: Prayer in congregation on a rainy night
(35) باب الْجَمَاعَةِ فِي اللَّيْلَةِ الْمَطِيرَةِ ‏
Sunan Ibn Majah 936 
It was narrated that Abu Malih said:
“I went out on a rainy night (for congregational prayer), and when I came back I asked for the door to be opened. My father said: ‘Who is this?’ I said: ‘Abu Malih.’ He said: ‘We were with the Messenger of Allah (ﷺ) at Hudaybiyah and it rained a little, such that the soles of our sandals did not get wet. The announcer of the Messenger of Allah (ﷺ) called out: ‘Perform your prayer at your camps.’”
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ إِبْرَاهِيمَ، عَنْ خَالِدٍ الْحَذَّاءِ، عَنْ أَبِي الْمَلِيحِ، قَالَ خَرَجْتُ فِي لَيْلَةٍ مَطِيرَةٍ فَلَمَّا رَجَعْتُ اسْتَفْتَحْتُ فَقَالَ أَبِي مَنْ هَذَا قَالَ أَبُو الْمَلِيحِ ‏.‏ قَالَ لَقَدْ رَأَيْتُنَا مَعَ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ يَوْمَ الْحُدَيْبِيَةِ وَأَصَابَتْنَا سَمَاءٌ لَمْ تَبُلَّ أَسَافِلَ نِعَالِنَا فَنَادَى مُنَادِي رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ ‏ "‏ صَلُّوا فِي رِحَالِكُمْ ‏"‏ ‏.‏
