Sayyiduna Mihjan (may Allah be pleased with him) said: I came to the Prophet (peace and blessings be upon him) and spoke to him about a need. Then the prayer was established while I was sitting. The Prophet (peace and blessings be upon him) prayed, then when he finished he found me sitting and said: "Are you not a Muslim?" I said: "Of course, O Messenger of Allah." He (peace and blessings be upon him) said: "Then what prevented you from praying with us?" I said: "I had already prayed at my lodging." He (peace and blessings be upon him) said: "Even if you have already prayed at your lodging."
