Is it permissible to perform a qada prayer before performing the prescribed prayer of that time period?

If a person who missed a prayer and already had missed prayers before, and the number of them has not been six in total, which means this person is a sahib al-tartib, he should first perform qada for the missed prayers and then perform the prayer of the time. If he has six or more missed prayers, which means this person is not a sahib al-tartib, he may perform them whenever he wants except prohibited times (Haddadi, al-Jawhara, I,80; Mawsili, al-Ikhtiyar, I, 221-223).
