Are the post-prayer dhikr recited after the rawatib and nafilah prayers?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: Are the post-prayer dhikr recited after the rawatib and nafilah prayers, or are they not recited except after the obligatory prayers only?

Answer:
They are recited after the obligatory prayers, because no dhikr has been reported for the rawatib; the dhikr was reported after the obligatory prayers. Yes.
