Placing The Right Hand On The Left In THe Prayer
Sunan Abi Dawud
حَدَّثَنَا أَبُو تَوْبَةَ، حَدَّثَنَا الْهَيْثَمُ، - يَعْنِي ابْنَ حُمَيْدٍ - عَنْ ثَوْرٍ، عَنْ سُلَيْمَانَ بْنِ مُوسَى، عَنْ طَاوُسٍ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَضَعُ يَدَهُ الْيُمْنَى عَلَى يَدِهِ الْيُسْرَى ثُمَّ يَشُدُّ بَيْنَهُمَا عَلَى صَدْرِهِ وَهُوَ فِي الصَّلاَةِ .
Narrated Tawus: The Messenger of Allah (ﷺ) used to place his right hand on his left hand, then he folded them strictly on his chest in prayer.
