عَنْ عَبَّادِ بْنِ تَمِيمٍ، عَنْ عَمِّهِ، قَالَ خَرَجَ النَّبِيُّ صلى الله عليه وسلم يَسْتَسْقِي فَتَوَجَّهَ إِلَى الْقِبْلَةِ يَدْعُو، وَحَوَّلَ رِدَاءَهُ، ثُمَّ صَلَّى رَكْعَتَيْنِ جَهَرَ فِيهِمَا بِالْقِرَاءَةِ.
Abbad bin Tamim narrated from his uncle, [Hazrat Abdullah bin Zaydra], who said: “The Prophetsa went out to pray for rain. He turned towards the qiblah, supplicating and then turned his cloak around [inside out]. After that, he performed two rak‘ahs and recited aloud in both of them.”
