Sayyiduna Anas (may Allah be pleased with him) narrates: A man from the Qais tribe entered (the mosque) while the Prophet Muhammad (peace and blessings be upon him) was delivering the sermon. The Prophet (peace and blessings be upon him) said to him: "You stand up and perform two rak‘ahs." The Prophet (peace and blessings be upon him) paused his sermon until he finished the prayer. This narration is reported in the same way from Sayyiduna Anas (may Allah be pleased with him), however, the narrator made an error in it. The correct version is: it is transmitted as a mursal narration from the father of Mu'tamir. However, Imam Ahmad ibn Hanbal has narrated it in this manner.
