It is narrated that Sulaym bin Itr al-Tujibi used to preach to the people while standing, so Sayyiduna Silah bin al-Harith al-Ghifari (may Allah be pleased with him), who was one of the Companions of the Prophet (peace and blessings be upon him), said to him: "By Allah, we did not abandon the covenant of our Prophet (peace and blessings be upon him), nor did we sever our ties of kinship, until you and your companions stood up among us (and brought this new practice)."
