What is the ruling on performing the sunnah after the adhan for one who has prayed the greeting of the mosque?

Question:
Honorable Shaykh, the questioner says: What is the ruling on performing the sunnah after the adhan, since I have already performed the greeting of the mosque beforehand?

Answer:
The sunnah after the adhan: if your intention is the rawatib, that is because the greeting of the mosque is for entering when one enters. If the adhan is called, the time has entered, and the pre-prayer rawatib becomes obligatory upon you, for example, for the Zuhr prayer. The rawatib for Zuhr is before and after it. As for 'Asr, Maghrib, and 'Isha', they do not have a rawatib before them. If you pray from the perspective of absolute voluntary prayer, there is no harm in that. Likewise, Fajr has a rawatib before it. That means Zuhr and Fajr have a rawatib before them, and the others do not have a rawatib before them; rather, one prays before them from the perspective of absolute voluntary prayer. In this, you have a choice: if you wish, you stand and pray an absolute voluntary prayer, and if you wish, you remain sitting.
