Abu Ma'mar (may Allah have mercy on him) says: The iqamah was called, and they kept pushing one another forward. Hudhayfah (may Allah be pleased with him) went forward and led them in prayer, then said: "You must find an imam other than me, or else pray individually." Al-Mughirah says: I narrated this hadith to Mujahid (may Allah have mercy on him) while Ibrahim was present, and Mujahid said: "Furada (singly)." Ibrahim said: "Furada and wuhdanan are the same."
