Sahih Muslim 894d

'Abbad b. Tamim Mazini heard his uncle, who was one of the Companions of the Messenger of Allah ﷺ, as saying: The Messenger of Allah ﷺ went out one day in order to pray for rain. He turned his back towards people, supplicated before Allah, facing towards Qibla, and turned his mantle round and then observed two rak'ahs of prayer.

وَحَدَّثَنِي أَبُو الطَّاهِرِ، وَحَرْمَلَةُ، قَالاَ أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ، شِهَابٍ قَالَ أَخْبَرَنِي عَبَّادُ بْنُ تَمِيمٍ الْمَازِنِيُّ، أَنَّهُ سَمِعَ عَمَّهُ، وَكَانَ، مِنْ أَصْحَابِ رَسُولِ اللَّهِ ﷺ يَقُولُ خَرَجَ رَسُولُ اللَّهِ ﷺ يَوْمًا يَسْتَسْقِي فَجَعَلَ إِلَى النَّاسِ ظَهْرَهُ يَدْعُو اللَّهَ وَاسْتَقْبَلَ الْقِبْلَةَ وَحَوَّلَ رِدَاءَهُ ثُمَّ صَلَّى رَكْعَتَيْنِ .
