Usamah attended the Prophet ﷺ on the occasion of the treaty of al-Hudaybiyyah on Friday. The rain fell as little as the soles of the shoes of the people were not set. He (the Prophet) commanded them to offer Friday prayer in their dwellings.  

أَنَّهُ شَهِدَ النَّبِيَّ ﷺ زَمَنَ الْحُدَيْبِيَةِ فِي يَوْمِ جُمُعَةٍ وَأَصَابَهُمْ مَطَرٌ لَمْ تَبْتَلَّ أَسْفَلُ نِعَالِهِمْ فَأَمَرَهُمْ أَنْ يُصَلُّوا فِي رِحَالِهِمْ  

[Machine] "He witnessed Prophet Muhammad, peace be upon him, during the time of Hudaybiyah, and they were struck by rain on a Friday that did not wet the soles of their footwear. Then the Prophet, peace be upon him, commanded them to pray in their places of encampment. This is a hadith with a sound chain of narration. The two sheikhs have cited its narrators as evidence, and it is of the kind for which they requested a continuous chain of transmission from the Successor to the Companions, and they did not exclude it." This is authentic.  

أَنَّهُ شَهِدَ النَّبِيَّ ﷺ زَمَنَ الْحُدَيْبِيَةِ وَأَصَابَهُمْ مَطَرٌ فِي يَوْمِ جُمُعَةٍ لَمْ يَبُلَّ أَسْفَلَ نِعَالِهِمْ «فَأَمَرَهُمُ النَّبِيُّ ﷺ أَنْ يُصَلُّوا فِي رِحَالِهِمْ» هَذَا «حَدِيثٌ صَحِيحُ الْإِسْنَادِ وَقَدِ احْتَجَّ الشَّيْخَانِ بِرُوَاتِهِ وَهُوَ مِنَ النَّوْعِ الَّذِي طَلَبُوا الْمُتَابِعَ فِيهِ لِلتَّابِعِيِّ عَنِ الصَّحَابِيِّ وَلَمْ يُخَرِّجَاهُ» صحيح
