Sayyiduna Samurah bin Jundub al-Fazari (may Allah be pleased with him), the Companion of the Messenger of Allah (peace and blessings be upon him), said: "Whoever leaves the Friday prayer without an excuse should give a dirham or half a dirham in charity, or a sa' or a mudd."
Sa'id said: I asked Qatadah whether he attributed it to the Prophet (peace and blessings be upon him), and he was unsure about that. Sa'id said: Some of our companions have mentioned that Qatadah attributed it to the Prophet (peace and blessings be upon him).
