10. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad who has the following: Al-Husayn has mentioned that he (the Imam), ’Alayhi al-Salam, commanded a man, who was asking him (the Imam) about a man who was performing Salah (prayer) on the side of a man standing on his left. He did not know (that he is to stand on the right side of the Imam) and then he learned in his Salah (prayer) how he is to do. He (the Imam) commanded to turn him to his right.”
