79 - حَدَّثَنَا الْحُمَيْدِيُّ، ثنا سُفْيَانُ، ثنا أَبُو يَعْفُورَ، عَنْ مُصْعَبِ بْنِ سَعْدِ بْنِ أَبِي وَقَّاصٍ قَالَ صَلَّيْتُ إِلَي جَنْبِ أَبِي فَطَبَّقْتُ فَنَهَانِي وَقَالَ «قَدْ كُنَّا نَفْعَلُهُ فَنُهِينَا يَعْنِي النَّبِيَّ صَلَّي اللهُ عَلَيْهِ وَسَلَّمَ»
Sayyiduna Sa’d bin Abi Waqqas’s (may Allah be pleased with him) son, Mus’ab, narrates: I performed prayer beside my father, and I placed both my hands between my knees. He forbade me from doing so and said: We used to do this before, then we were prohibited from it (i.e., the Prophet Muhammad, peace and blessings be upon him, forbade us).
