It was narrated from Malik bin Numair Al-Khuza’i that his father said:
"I saw the Prophet (ﷺ) putting his right hand on his right thigh during prayer, and pointing with his finger."
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا وَكِيعٌ، عَنْ عِصَامِ بْنِ قُدَامَةَ، عَنْ مَالِكِ بْنِ نُمَيْرٍ الْخُزَاعِيِّ، عَنْ أَبِيهِ، قَالَ رَأَيْتُ النَّبِيَّ ـ صلى الله عليه وسلم ـ وَاضِعًا يَدَهُ الْيُمْنَى عَلَى فَخِذِهِ الْيُمْنَى فِي الصَّلاَةِ وَيُشِيرُ بَإِصْبَعِهِ .
