bayhaqi:6457Abū Saʿīd b. Abū ʿAmr > Abū al-ʿAbbās > al-Rabīʿ > al-Shāfiʿī > Man Lā Attahim > Yazīd b. al-Hād

[Machine] Abu Al-Abbas narrated from Ar-Rabi' that Ash-Shafi'i narrated from someone who he does not accuse of lying, that the Prophet ﷺ used to say when it rained: "Come out with us to this which Allah has made pure, so we can purify ourselves from it and praise Allah for it." This hadith is interrupted and it was narrated from Umar regarding it.  

البيهقي:٦٤٥٧أَخْبَرَنَا أَبُو سَعِيدِ بْنُ أَبِي عَمْرٍو

ثنا أَبُو الْعَبَّاسِ أنبأ الرَّبِيعُ أنبأ الشَّافِعِيُّ أنبأ مَنْ لَا أَتَّهِمُ عَنْ يَزِيدَ بْنِ الْهَادِ أَنَّ النَّبِيَّ ﷺ كَانَ إِذَا سَالَ السَّيْلُ قَالَ اخْرُجُوا بِنَا إِلَى هَذَا الَّذِي جَعَلَهُ اللهُ طَهُورًا فَنَتَطَهَّرَ مِنْهُ وَنَحْمَدَ اللهَ عَلَيْهِ هَذَا مُنْقَطِعٌ وَرُوِيَ فِيهِ عَنْ عُمَرَ
