Saying "Amma ba'd" after praise in the sermon is Sunnah.
`Sayyiduna Abu Humayd Sa'idi (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings be upon him) stood up one night after the prayer and recited the Tashahhud and praised Allah as He deserves to be praised, then said, "Amma ba'd!."
