"I saw the Prophet ﷺ on the day when he went out to offer the Istisqa' prayer. He turned his back towards the people and faced the Qibla and asked Allah for rain. Then he turned his cloak inside out and led us in a two rakʿat prayer and recited the Qur'an aloud in them."  

رَأَيْتُ النَّبِيَّ ﷺ يَوْمَ خَرَجَ يَسْتَسْقِي قَالَ فَحَوَّلَ إِلَى النَّاسِ ظَهْرَهُ وَاسْتَقْبَلَ الْقِبْلَةَ يَدْعُو ثُمَّ حَوَّلَ رِدَاءَهُ ثُمَّ صَلَّى لَنَا رَكْعَتَيْنِ جَهَرَ فِيهِمَا بِالْقِرَاءَةِ
