[Machine] When I would go into the bowing position, I would place my hands between my knees. My father, Saad ibn Malik, saw me doing this and prohibited me from it, saying that we used to do it, but then we were forbidden from it.  

أحمد:١٥٧٦ – حَدَّثَنَا وَكِيعٌ حَدَّثَنَا ابْنُ أَبِي خَالِدٍ عَنِ الزُّبَيْرِ بْنِ عَدِيٍّ عَنْ مُصْعَبِ بْنِ سَعْدٍ قَالَ

كُنْتُ إِذَا رَكَعْتُ وَضَعْتُ يَدَيَّ بَيْنَ رُكْبَتَيَّ قَالَ فَرَآنِي أَبِي سَعْدُ بْنُ مَالِكٍ فَنَهَانِي وَقَالَ إِنَّا كُنَّا نَفْعَلُهُ فَنُهِينَا عَنْهُ

ذِكْرُ الْبَيَانِ بِأَنَّ التَّطْبِيقَ فِي الرُّكُوعِ كَانَ فِي أَوَّلِ الْإِسْلَامِ، ثُمَّ نُسِخَ ذَلِكَ بِالْأَمْرِ بِوَضْعِ الْأَيْدِي عَلَى الرُّكَبِ

كُنْتُ إِذَا صَلَّيْتُ طَبَّقَتْ وَوَضَعْتُ يَدَيَّ بَيْنَ رُكْبَتَيَّ فَرَآنِي أَبِي سَعْدٌ فَقَالَ كُنَّا نَفْعَلُ هَذَا فَنُهِينَا عَنْهُ وَأُمِرْنَا بِالرُّكَبِ
