The Messenger of Allah ﷺ went to the place of prayer and prayed for rain and turned round his mantle while facing the Qibla.  

سَمِعْتُ عَبْدَ اللَّهِ بْنَ زَيْدٍ الْمَازِنِيَّ يَقُولُ خَرَجَ رَسُولُ اللَّهِ ﷺ إِلَى الْمُصَلَّى فَاسْتَسْقَى وَحَوَّلَ رِدَاءَهُ حِينَ اسْتَقْبَلَ الْقِبْلَةَ  

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  

'Abdullah b. Zaid al-Ansari reported that the Messenger of Allah ﷺ went out to the place of prayer in order to offer prayer for rainfall. And when he intended to make supplication he faced Qibla and turned round his mantle.  

أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ ﷺ خَرَجَ إِلَى الْمُصَلَّى يَسْتَسْقِي وَأَنَّهُ لَمَّا أَرَادَ أَنْ يَدْعُوَ اسْتَقْبَلَ الْقِبْلَةَ وَحَوَّلَ رِدَاءَهُ  

The Messenger of Allah ﷺ went out one day in order to pray for rain. He turned his back towards people, supplicated before Allah, facing towards Qibla, and turned his mantle round and then observed two rak'ahs of prayer.  

أَنَّهُ سَمِعَ عَمَّهُ وَكَانَ مِنْ أَصْحَابِ رَسُولِ اللَّهِ ﷺ يَقُولُ خَرَجَ رَسُولُ اللَّهِ ﷺ يَوْمًا يَسْتَسْقِي فَجَعَلَ إِلَى النَّاسِ ظَهْرَهُ يَدْعُو اللَّهَ وَاسْتَقْبَلَ الْقِبْلَةَ وَحَوَّلَ رِدَاءَهُ ثُمَّ صَلَّى رَكْعَتَيْنِ
