Musannaf Ibn Abi Shayba 3:497

Abu Bakr narrated to us, he said: Sufyan ibn ‘Uyaynah narrated to us, from Safwan ibn Sulaym, from Nafi‘ ibn Jubayr, from Sahl ibn Abi Hathmah, who attributed it to the Prophet (ﷺ), he said: "When one of you prays towards a sutrah (barrier), let him draw near to it, so that the Shaytan does not cut off his prayer."
