What is the ruling on the two rak'ahs of supererogatory prayer immediately after the Friday prayer?

It is recommended to pray the Sunnah (supererogatory) prayer for Jumu'ah after completing the post-prayer remembrances, because connecting a fard (obligatory) prayer directly with another prayer is prohibited. As the Prophet, peace and blessings be upon him, commanded us: "Do not connect a prayer until you speak or leave."
