Is it permissible to perform the rawatib voluntary prayers after combining the Zuhr and Asr prayers, given that voluntary prayer after Asr is prohibited?

Summary

The fatwa states that there is no objection and it is permitted to perform the rawatib voluntary prayers after combining the Zuhr and Asr prayers. Following Imam al-Nawawi and Sheikh Zakariya al-Ansari, for combined Zuhr and Asr, whether taqdim or ta'khir, the qabliyah Zuhr prayer is performed first, then the two obligatory prayers, then the ba'diyah Zuhr and finally the Asr voluntary prayer. For combined Maghrib and Isha, both obligatory prayers are performed first, followed by the Maghrib voluntary prayer, the Isha voluntary prayer and witr.
