If one prays the post-Maghrib sunnah in another mosque, is he required to pray the greeting of the mosque?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: I pray Maghrib in the mosque next to our house, and after the prayer I come directly here to attend the lesson. So, when I arrive at this mosque, I pray two rak'ahs intending them as the Maghrib sunnah, and I include in this intention the greeting for this mosque. The question is: Is my action correct?

Answer:
If Allah wills, it is correct. If you delay the rawatib and pray it here, it suffices for the greeting of the mosque; because it is true that you prayed two rak'ahs before sitting down. Yes.
