"The Prophet ﷺ went out to the Musalla to offer the Istisqa' prayer, faced the Qibla and offered a two rakʿat prayer and turned his cloak inside out." Narrated Abu Bakr, "The Prophet ﷺ put the right side of his cloak on his left side."
خَرَجَ النَّبِيُّ ﷺ إِلَى الْمُصَلَّى يَسْتَسْقِي وَاسْتَقْبَلَ الْقِبْلَةَ فَصَلَّى رَكْعَتَيْنِ وَقَلَبَ رِدَاءَهُ قَالَ سُفْيَانُ فَأَخْبَرَنِي الْمَسْعُودِيُّ عَنْ أَبِي بَكْرٍ قَالَ جَعَلَ الْيَمِينَ عَلَى الشِّمَالِ
Ibn Tamim narrated on the authority of his uncle ('Abdullah b. Zaid) that the Messenger of Allah ﷺ went out to the place of prayer and prayed for rain and faced towards Qibla, and turned round his mantle and prayed two rak'ahs.
خَرَجَ النَّبِيُّ ﷺ إِلَى الْمُصَلَّى فَاسْتَسْقَى وَاسْتَقْبَلَ الْقِبْلَةَ وَقَلَبَ رِدَاءَهُ وَصَلَّى رَكْعَتَيْنِ
[Machine] The Messenger of Allah ﷺ went out to the prayer area to pray for rain. He faced the qiblah (direction of prayer), turned his robe inside out, and prayed two units of prayer. Sufyan said, "He turned his robe in such a way that the right became the left and the left became the right."
أَنَّ رَسُولَ اللهِ ﷺ خَرَجَ إِلَى الْمُصَلَّى يَسْتَسْقِي فَاسْتَقْبَلَ الْقِبْلَةَ وَقَلَبَ رِدَاءَهُ وَصَلَّى رَكْعَتَيْنِ قَالَ سُفْيَانُ قَلْبُ الرِّدَاءِ جَعْلُ الْيَمِينِ الشِّمَالَ وَالشِّمَالِ الْيَمِينَ
