Sahih Muslim 535a

We have been forbidden from it and no mention of that has been made what follows it.

حَدَّثَنَا خَلَفُ بْنُ هِشَامٍ، حَدَّثَنَا أَبُو الأَحْوَصِ، ح قَالَ وَحَدَّثَنَا ابْنُ أَبِي عُمَرَ، حَدَّثَنَا سُفْيَانُ، كِلاَهُمَا عَنْ أَبِي يَعْفُورٍ، بِهَذَا الإِسْنَادِ إِلَى قَوْلِهِ فَنُهِينَا عَنْهُ ‏.‏…

"I prayed beside my father and I put my hands between my knees, and he told me: 'Put your hands on your knees.' Then I did that again and he struck my hands and said: 'We were forbidden to do that, and we were commanded to put our hands on our knees.'"

اضْرِبْ بِكَفَّيْكَ عَلَى رُكْبَتَيْكَ ‏.‏ قَالَ ثُمَّ فَعَلْتُ ذَلِكَ مَرَّةً أُخْرَى فَضَرَبَ يَدِي وَقَالَ إِنَّا قَدْ نُهِينَا عَنْ هَذَا وَأُمِرْنَا أَنْ نَضْرِبَ بِالأَكُفِّ عَلَى الرُّكَبِ ‏.‏

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.

رَكَعْتُ فَقُلْتُ بِيَدَىَّ هَكَذَا - يَعْنِي طَبَّقَ بِهِمَا وَوَضَعَهُمَا بَيْنَ فَخِذَيْهِ - فَقَالَ أَبِي قَدْ كُنَّا نَفْعَلُ هَذَا ثُمَّ أُمِرْنَا بِالرُّكَبِ ‏.‏
