عَنْ أَبِي مَلِيحِ بْنِ أُسَامَةَ عَنْ أَبِيهِ قَالَ: أَصَابَ النَّاسَ فِي يَوْمِ جُمُعَةٍ يَعْنِي مَطَرًا فَأَمَرَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَنُودِيَ: أَنَّ الصَّلَاةَ الْيَوْمَ أَوِ الْجُمُعَةَ الْيَوْمَ فِي الرِّحَالِ
Ammar bin Abu Ammar passed by Sayyiduna Abdur Rahman bin Samurah (may Allah be pleased with him), while he was at the Umm Abdullah canal (in Basra), (the rain was so heavy that) its water was flowing over his children and slaves. Ammar said: Abu Saeed! Go to perform the Friday prayer. He replied from ahead that the Messenger of Allah (peace and blessings be upon him) said: When it is a day of heavy rain, everyone should perform the prayer in his own house.
