What is the ruling on not maintaining prayer and being negligent regarding it, and is it permissible for the wife to request not living with her husband because of that?

What was advised to the family and wife is the truth and the correct path. It is obligatory to submit to Allah's command by establishing prayer and persevering in it before it is too late, especially since the majority of scholars believe that abandoning prayer is an act of disbelief. The questioner is advised to return to Allah and to persevere in the obligatory duties, and to increase in supererogatory acts to compensate for what has passed. It is more prudent to make up for the missed obligatory prayers.
