قَالَ الْحَارِثُ بْنُ مِسْكِينٍ قِرَاءَةً عَلَيْهِ وَأَنَا أَسْمَعُ، عَنِ ابْنِ وَهْبٍ، عَنِ ابْنِ أَبِي ذِئْبٍ، وَيُونُسَ، عَنِ ابْنِ شِهَابٍ، قَالَ أَخْبَرَنِي عَبَّادُ بْنُ تَمِيمٍ، أَنَّهُ سَمِعَ عَمَّهُ، وَكَانَ، مِنْ أَصْحَابِ رَسُولِ اللَّهِ صلى الله عليه وسلم يَقُولُ خَرَجَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَوْمًا يَسْتَسْقِي فَحَوَّلَ إِلَى النَّاسِ ظَهْرَهُ يَدْعُو اللَّهَ وَيَسْتَقْبِلُ الْقِبْلَةَ وَحَوَّلَ رِدَاءَهُ ثُمَّ صَلَّى رَكْعَتَيْنِ ‏.‏ قَالَ ابْنُ أَبِي ذِئْبٍ فِي الْحَدِيثِ وَقَرَأَ فِيهِمَا ‏.‏

It was narrated that Ibn Shihab said: "Abbad bin Tamim told me that he heard his paternal uncle, who was one of the companions of the Messenger of Allah (PBUH) say: "The Messenger of Allah (PBUH) went out one day to pray for rain. He turned his back toward the people, praying to Allah (SWT), and he turned to face the Qiblah. He turned his rida' around, then he prayed two rak'ahs." (One of the narrators) Ibn Abi Dhi'b said in the hadith: "And he recited in them both." Translation Not Available
