It is narrated from one of the Companions of the Prophet (peace and blessings be upon him) (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) offered the Asr prayer, and then a man stood up to pray (a voluntary prayer). Sayyiduna Umar (may Allah be pleased with him) saw him and said to him: "Sit down, for the People of the Book were destroyed precisely because there was no separating interval between their prayers." (Hearing this,) the Messenger of Allah (peace and blessings be upon him) said: "Ibn al-Khattab has spoken very well and rightly."
