How do we pray the two Rak'ahs of Sunnah before Fajr to be counted among the twelve regular Sunnah prayers? And are they performed before or after the Adhan of Fajr, especially since the people of the Maghreb pray Fajr and then Subh?

The twelve regular (optional) prayers, for which a house will be built in Paradise for those who consistently perform them, are: two rak'ahs before Fajr, four rak'ahs before Dhuhr, two rak'ahs after it, two rak'ahs after Maghrib, and two rak'ahs after Ishaa'. What a Muslim performs after the call to Fajr prayer and before the obligatory prayer is the Sunnah of Fajr, and it is among these regular prayers.
