‘Ali and Mu'adh b. Jabal reported God’s Messenger as saying, “When any of you comes to pray and the imam is at a certain point, he must do as the imam does.” Tirmidhi transmitted it and said this is a gharib tradition.
Reported by At-Tirmidhi (No. 591). Cited in Mishkat al-Masabih (No. 1142).
‘Ali ibn Abi Tālib and Mu‘ādh ibn Jabal (may Allah be pleased with both of them) reported that the Prophet (may Allah's peace and blessings be upon him) said: "When one of you joins the prayer and finds the Imām in a certain position, he should do what the Imām is doing."
