Sayyiduna Jabir (may Allah be pleased with them both) narrates that Sayyiduna Ibn Mas'ud (may Allah be pleased with him) entered the mosque while the Prophet (peace and blessings be upon him) was standing delivering the sermon. He sat down beside Sayyiduna Ubayy (may Allah be pleased with him) and asked him about something, but he did not answer him. Then when (the Prophet (peace and blessings be upon him), having finished the prayer,) turned around, Sayyiduna Ibn Mas'ud (may Allah be pleased with him) said to Sayyiduna Ubayy (may Allah be pleased with him): "What prevented you from answering me?" He said: "You did not get the (full) reward of the Friday prayer with us." He asked: "Why is that?" He said: "Because you spoke while the Prophet (peace and blessings be upon him) was delivering the sermon." Then the Messenger of Allah (peace and blessings be upon him) said: "Ubayy has spoken the truth."
