Nafi‘ told that he heard Ibn ‘Umar say God’s Messenger forbade anyone to make another get up and then sit in his place. When asked whether this applied to the Friday prayer, Nafi' said that it applied both to the Friday prayer and to other occasions.
Sahl b. Mu'adh b. Anas al-Juhani told that his father reported God’s Messenger as saying, "If anyone steps over people on Friday he will be made a bridge to jahannam."
Tirmidhi transmitted it and said this is a gharib tradition.
