One day the Messenger of Allah ﷺ went out to make supplication for rain. He turned his back towards the people praying to Allah, the Exalted. The narrator Sulaiman b. Dawud said: He faced the qiblah and turned around his cloak and then offered two rak'ahs of prayer. The narrator Ibn Abi Dhi'b said: He recited from the Qur'an in both of them. The version of Ibn al-Sarh adds: By it he means in a loud voice.
أَنَّهُ سَمِعَ عَمَّهُ وَكَانَ مِنْ أَصْحَابِ رَسُولِ اللَّهِ ﷺ يَقُولُ خَرَجَ رَسُولُ اللَّهِ ﷺ يَوْمًا يَسْتَسْقِي فَحَوَّلَ إِلَى النَّاسِ ظَهْرَهُ يَدْعُو اللَّهَ ﷻ قَالَ سُلَيْمَانُ بْنُ دَاوُدَ وَاسْتَقْبَلَ الْقِبْلَةَ وَحَوَّلَ رِدَاءَهُ ثُمَّ صَلَّى رَكْعَتَيْنِ قَالَ ابْنُ أَبِي ذِئْبٍ وَقَرَأَ فِيهِمَا زَادَ ابْنُ السَّرْحِ يُرِيدُ الْجَهْرَ
