Is it permissible to pray Fajr at home in order to accompany one's wife who is afraid of being left alone in a mountainous area, or if she fell asleep due to staying up late with her young daughter?

The permissibility of praying Fajr at home depends on the ruling regarding congregational prayer in the mosque. According to the majority of scholars, it is permissible because it is not obligatory, while others consider it obligatory. Jurists have differed on whether congregational prayer is obligatory specifically in the mosque or elsewhere. It is better for a Muslim to pray in the mosque if possible, but there is no blame on him if it is not possible due to an excuse such as caring for his young daughter or his wife's justified fear, while paying attention to the noble verse: "O you who have believed, indeed, among your wives and your children are enemies to you, so beware of them" (At-Taghabun: 14), which Ibn Kathir interpreted as referring to being distracted by them from righteous deeds.
