If one forgets the Duha prayer and the sun has passed its zenith, does he make it up after the adhan for Dhuhr or after the Dhuhr prayer?

The questioner : And this person says: If the sun has passed its zenith and I have not prayed the Duha sunnah because I forgot it, do I make it up after the adhan for Dhuhr or after the Dhuhr prayer?

The Shaykh : It appears that he makes it up after the adhan for Dhuhr, before the Dhuhr prayer, due to the generality of the saying of the Messenger of Allah (peace and blessings be upon him): And this person forgot the Duha prayer, so he prays it when he remembers it.
