The Sunnah of the Rawatib and the Greeting of the Mosque When Arriving Early

Question:
Regarding the Sunnah of the Rawatib, O Shaykh. If a person goes to the mosque early, by half an hour, or by forty-five minutes, or by ten minutes. Of course, he is the one who enters the mosque and prays the Sunnah of the greeting of the mosque. But if the Adhan is called, does he pray two Rak'ahs, especially in 'Isha' and Maghrib, which do not have Rawatib Sunnahs? Or how is it? Or is the greeting of the mosque sufficient for all the prayers if he goes early?

Answer:
When he enters the mosque, he prays two Rak'ahs as the greeting of the mosque; this is a confirmed Sunnah. As for the Rawatib, they are after the time enters, after the Adhan. He performs the pre-prayer Rawatib, and if he prays, he performs the post-prayer Rawatib. Yes.
