Sahih al-Bukhari · Book 80: Invocations · To invoke Allah while facing the Qiblah
Narrated `Abdullah bin Zaid:
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ ، حَدَّثَنَا وُهَيْبٌ ، حَدَّثَنَا عَمْرُو بْنُ يَحْيَى ، عَنْ عَبَّادِ بْنِ تَمِيمٍ ، عَنْ عَبْدِ اللَّهِ بْنِ زَيْدٍ ، قَالَ خَرَجَ النَّبِيُّ صلى الله عليه وسلم إِلَى هَذَا الْمُصَلَّى يَسْتَسْقِي، فَدَعَا وَاسْتَسْقَى ثُمَّ اسْتَقْبَلَ الْقِبْلَةَ وَقَلَبَ رِدَاءَهُ.
Allah's Messenger (ﷺ) went out to this Musalla (praying place) to offer the prayer of Istisqa.' He invoked Allah for rain and then faced the Qibla and turned his Rida' (upper garment) inside out.
