Nafi' (may Allah have mercy on him) says that Sayyiduna Ibn Umar (may Allah be pleased with them both) used to go to the mosque on Friday and perform several rak'ahs of prayer in which he would stand for a long time. When the Imam would leave, he would go to his house and pray two rak'ahs and would say that the Prophet (peace and blessings of Allah be upon him) used to do the same.
