Is the supererogatory Dhuhr prayer (two or four rak'ahs) to be performed after the Dhuhr prayer by one who missed the Jumu'ah prayer?

If you miss the Friday prayer and pray Dhuhr instead, the Sunnah is to pray the Dhuhr ratibah (supererogatory prayers) with it. This consists of two rak'ahs after it, or four rak'ahs. It was reported from Ibn Umar (may Allah be pleased with them both) that he prayed with the Messenger of Allah (peace and blessings be upon him) two rak'ahs before Dhuhr and two rak'ahs after it. And it was reported from Umm Habibah (may Allah be pleased with her) that whoever prays four rak'ahs before Dhuhr and four after it, Allah will forbid him from the Hellfire. The matter is broad.
