Is it prescribed to pray two rak'ahs before reciting the supplication for the completion of the Qur'an, or is it recited without prayer?

It is recommended to supplicate after completing the recitation of the Noble Qur’an with whatever good one desires for this world and the Hereafter. The supplication should be made immediately after finishing Surat An-Nas. There is no prescribed two-rak'ah prayer after the completion, as there is no evidence for it.
