Is it more correct to go to the mosque to pray in congregation, leaving the protection of the home to Allah, or to stay and pray at home for fear of theft, in light of the widespread crimes and theft due to the war?

Congregational prayer is not obligatory in the mosque, and it is permissible to perform it at home, according to the preponderant opinion. Fear for one's property is among the excuses that permit abandoning Friday prayer and congregational prayer. Therefore, it is permissible to pray in congregation at home if going to the mosque harms the brother, and they can alternate going to the mosque to appease their feelings.
