There is no such thing as saying, how do we combine.
The greeting of the mosque with the sunnah of Fajr. There is no such thing as the greeting of the mosque with the sunnah of Fajr, according to the correct opinion.
The greeting of the mosque is when you enter the mosque at a time other than prayer time.
Is there a greeting of the mosque? For example, if someone enters the mosque after the Isha prayer.
For example, he prayed Isha and prayed the sunnah of Isha.
He sat in the mosque to attend a lesson, or to see someone, or he entered to read.
For example, from the Quran, it is said to him: Do not sit out of respect for the mosque until you pray.
This is the greeting of the mosque, but if a person enters and the 'isha prayer is being held.
This renews the mosque, the 'isha prayer renews the mosque. The imam does not sit until he prays.
So if he prays 'isha with the people, he has greeted the mosque.
So whoever enters the mosque after the adhan of dhuhr, the sunnah of dhuhr.
It is the greeting of the mosque. Whoever enters the mosque after the adhan of fajr.
So the sunnah of Fajr is a greeting; there is no such thing as the greeting of the mosque and the sunnah.
Fajr, there is no such thing as the greeting of the mosque and the sunnah.
Dhuhr, but what matters is that he does not sit.
Until he prays two rak'ahs, as the Prophet ﷺ said: If one of you enters the mosque, he should not sit until he prays.
Two rak'ahs, so if you enter at the time of prayer.
Whether it is obligatory, missed, or a regular sunnah, you have prayed two rak'ahs.
But if you enter at a time when there is no prayer, then it is said: pray two rak'ahs.
