عَنِ ابْنِ عُمَرَ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا قَعَدَ فِي التَّشَهُّدِ وَضَعَ يَدَهُ الْيُسْرَى عَلَى رُكْبَتِهِ الْيُسْرَى وَوَضَعَ يَدَهُ الْيُمْنَى عَلَى رُكْبَتِهِ الْيُمْنَى وَعَقَدَ ثَلَاثًا وَخمسين وَأَشَارَ بالسبابة
Ibn ‘Umar said that when God’s Messenger sat at the tashahhud he placed his left hand on his left knee and his right hand on his right knee, counted fifty-three on his knuckles, and pointed with the forefinger.
