"The Messenger of Allah went out with the people to seek rain. So he led them in prayer for two Rak'ah, reciting aloud in them, turning his upper wrap around, raising his hands, requesting rain, and facing the Qiblah."  

أَنَّ رَسُولَ اللَّهِ ﷺ خَرَجَ بِالنَّاسِ يَسْتَسْقِي فَصَلَّى بِهِمْ رَكْعَتَيْنِ جَهَرَ بِالْقِرَاءَةِ فِيهِمَا وَحَوَّلَ رِدَاءَهُ وَرَفَعَ يَدَيْهِ وَاسْتَسْقَى وَاسْتَقْبَلَ الْقِبْلَةَ قَالَ وَفِي الْبَابِ عَنِ ابْنِ عَبَّاسٍ وَأَبِي هُرَيْرَةَ وَأَنَسٍ وَآبِي اللَّحْمِ  

The Messenger of Allah ﷺ took the people out (to the place of prayer) and prayed for rain. He led them in two rak'ahs of prayer in the course of which he recited from the Qur'an in a loud voice. He turned around his cloak and raised his hands, prayed for rain and faced the qiblah (Using translation from Abū Dāʾūd 1161)   

خَرَجَ رَسُولُ اللهِ ﷺ بِالنَّاسِ يَسْتَسْقِي فَصَلَّى بِهِمْ رَكْعَتَيْنِ وَجَهَرَ بِالْقِرَاءَةِ فِيهَا وَحَوَّلَ رِدَاءَهُ وَدَعَا وَاسْتَقْبَلَ الْقِبْلَةَ  

[Machine] The Messenger of Allah ﷺ went out to seek rainfall so he faced the Qibla, turned his back towards the people, flipped his cloak, and performed two loud Rak'ahs during which he recited out loud.  

أَنَّ رَسُولَ اللَّهِ ﷺ «خَرَجَ يَسْتَسْقِي فَاسْتَقْبَلَ الْقِبْلَةَ وَوَلَّى ظَهْرَهُ النَّاسَ وَقَلَبَ رِدَاءَهُ وَصَلَّى رَكْعَتَيْنِ جَهَرَ فِيهِمَا بِالْقِرَاءَةِ»
