Musannaf Ibn Abi Shayba 3:1824

Abu Bakr narrated to us, he said: Ibn Fudayl narrated to us, from ‘Ata’ ibn al-Sa’ib, from Abu ‘Abd al-Rahman, that he used to recite [the verse of] al-Sajdah, so he would prostrate. Then he would repeat it in that same sitting of his multiple times, [but] he would not prostrate.
