He built a mosque to pray in with his children; is the prayer valid in it?

Question:
May Allah reward you with good. After this, we move to the Nammas province via a message sent by a listener whose name is indicated by the letters Ayn, Ba, Dal. He says: I inform you that I am diligent in performing the prayer at its times, praise be to Allah. My home is about four hundred meters away from the village mosque. The road leading to this mosque is old and very rough, with many stones, a difficult slope, and a lack of lighting. I cross the valley to reach the mosque, so I built a mosque inside my courtyard and gather my family to perform the prayer. Is my prayer with my family valid? Knowing that there are no neighbors near us. May Allah keep you safe.

Answer:
If you are in the state and condition you described regarding the difficulty of reaching the mosque, and you have built a mosque in which you, your children, and your family pray, then there is no harm in that due to the presence of an excuse. However, if you go to the mosque and bear the hardship, that is better for you. As for the permissibility with the presence of this excuse, your action is permissible, if Allah wills. Yes.
