Intention for the regular Fajr prayer in the mosque and the greeting of the mosque

Question:
If a Muslim prays the two rak'ahs of Fajr at home, then goes to the mosque and wants to pray, how should his intention be? Is it the greeting of the mosque?

Answer:
He prays it at home; this is for the imam, who prays it at home and then goes out to lead the people in prayer, just as the Prophet (peace and blessings be upon him) used to do. As for anyone other than the imam, he prays it in the mosque. He prays the regular prayer in the mosque, and that suffices him for the greeting of the mosque; it suffices him for the greeting of the mosque. As for if he prays at home and then comes to the mosque, this is a matter of scholarly disagreement: does he pray the greeting of the mosque during the prohibited time because it is one of the prayers with a cause, or does he not pray it due to the general prohibition of prayer during the prohibited time? This is a matter of disagreement. But if he prays the regular prayer in the mosque, it suffices him for the greeting of the mosque, and the issue is resolved. He prayed during the prohibited time, and he said what he said, and this ends the matter. Yes.
