How can one reconcile the jurists' consensus on the invalidity of the prayer of whoever intentionally uncovers their nakedness during it, with the saying of some Malikis that covering the nakedness is not a condition for the validity of prayer, and that the prayer of whoever intentionally uncovers their nakedness is not invalidated?

The jurists differed regarding whether covering the 'awrah (intimate parts) is a condition for the validity of prayer. The majority of scholars held that it is a condition, while some Maliki jurists said it is obligatory or a Sunnah, though the prevalent view among them is that it is a condition. Those who consider it obligatory without it being a condition for validity, mandate re-performing the prayer within its prescribed time if the 'awrah was uncovered intentionally or unintentionally.
