Are the two rak'ahs that are prayed before Maghrib and 'Isha prayed before or after the Adhan, and by how many minutes?

The two rak'ahs before the Maghrib prayer are a Sunnah confirmed by word, deed, and tacit approval. These two rak'ahs are prayed after the adhan and before the Maghrib prayer. As for before the Isha adhan, no specific number of supererogatory prayers has been established, and the matter in this regard is broad. It is desirable to increase supererogatory prayers to draw closer to Allah Almighty.
