On the authenticity of the hadith: “Whoever prays Fajr in congregation, then remains in his place of prayer until the sun rises, and then prays two rak'ahs, is recorded for him the reward of a Hajj and 'Umrah”... the hadith?

The questioner:
May Allah reward you, Honorable Shaykh. This questioner says: What is the authenticity of the hadith: “Whoever prays Fajr in congregation, then remains in his place of prayer until the sun rises, and then prays two rak'ahs, is recorded for him the reward of a Hajj and 'Umrah”?

The Shaykh:
What appears to me is that it is a hasan (good) hadith, and there is no harm in it. It is good, and the remembrance of Allah is good. Yes.

The questioner:
He says, in the continuation of his question: And if I get up from my place of prayer to the other end of the mosque to get away from the air conditioner or the lights, will I still receive this reward?

The Shaykh:
If Allah wills, as long as you are in the mosque, you are in one place, especially since you say that you need to get up to move away from the air conditioner. There is no harm. Yes.
