It is narrated from Sayyiduna Qabath bin Ashyam al-Laythi (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The prayer of two men in which one leads the other is purer in the sight of Allah than the prayer of four praying individually; the prayer of four with one of them as imam is purer than the prayer of eight praying individually; and the prayer of eight with one of them as imam is purer in the sight of Allah than the prayer of a hundred praying individually." (After this) comes the mention of Sayyiduna Umayr bin Qatadah al-Laythi (may Allah be pleased with him).
