Narrated by:`Abbad bin Tamim's uncle
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.
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.
