The ruling on greeting the mosque before Fajr and the regular voluntary prayer of Fajr

Question:
The questioner says: If a person enters the mosque before the Fajr prayer and prays the greeting of the mosque, does that exempt him from the regular voluntary prayer of Fajr? And if he prays the reverse, meaning after the adhan, what is the ruling?

Answer:
If he prays before the dawn breaks, it does not count as the regular voluntary prayer of Fajr. The regular voluntary prayer of Fajr must be after the dawn breaks. So if he prays the greeting of the mosque before Fajr, he sits. When the dawn breaks and the mu'adhdhins call the adhan, he stands up and prays the regular voluntary prayer of Fajr, two rak'ahs. Yes.
