Going out of the Prophet (pbuh) to offer Istisqa' prayer

Sahih al-Bukhari · Book 15 · Hadith 1005

حَدَّثَنَا أَبُو نُعَيْمٍ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي بَكْرٍ، عَنْ عَبَّادِ بْنِ تَمِيمٍ، عَنْ عَمِّهِ، قَالَ خَرَجَ النَّبِيُّ صلى الله عليه وسلم يَسْتَسْقِي وَحَوَّلَ رِدَاءَهُ‏.‏

Narrated `Abbad bin Tamim's uncle: The Prophet (p.b.u.h) went out to offer the Istisqa' prayer and turned (and put on) his cloak inside out.
