Arabic (Original)
حَدَّثَنَا أَبُو نُعَيْمٍ حَدَّثَنَا مِسْعَرٌ عَنْ عَمْرِو بْنِ دِينَارٍ قَالَ سَمِعْتُ عَمْرَو بْنَ أَوْسٍ قَالَ أَخْبَرَنِي مَنْ سَمِعَ مُنَادِيَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ حِينَ قَامَتْ الصَّلَاةُ أَوْ حِينَ حَانَتْ الصَّلَاةُ أَوْ نَحْوَ هَذَا أَنْ صَلُّوا فِي رِحَالِكُمْ لِمَطَرٍ كَانَ.
English Translation
Abu Nu'aym told us: Mis'ar told us, from Amr ibn Dinar: I heard Amr ibn Aws say: A man who heard the caller of the Messenger of Allah, peace and blessings be upon him, informed me that, when the prayer was established, or when the time of prayer had come, or something like that, he called: "Pray in your dwellings" - because of rain that had fallen.
