5) Chapter: Concerning The Command Of Placing One's Hands On The Knees While In Ruku'and Abrogation Of Al-tatbiq
Ibn Sa'd reported:
I bowed and my hands were in this state, i. e. they were put together, palm to palm, and were placed between his thighs. My father said: We used to do like this but were later on commanded to place them on the knees.

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا وَكِيعٌ، عَنْ إِسْمَاعِيلَ بْنِ أَبِي خَالِدٍ، عَنِ الزُّبَيْرِ بْنِ عَدِيٍّ، عَنْ مُصْعَبِ بْنِ سَعْدٍ، قَالَ رَكَعْتُ فَقُلْتُ بِيَدَىَّ هَكَذَا - يَعْنِي طَبَّقَ بِهِمَا وَوَضَعَهُمَا بَيْنَ فَخِذَيْهِ - فَقَالَ أَبِي قَدْ كُنَّا نَفْعَلُ هَذَا ثُمَّ أُمِرْنَا بِالرُّكَبِ .
