Is it wise to perform numerous missed prayers in a way that suffices, alongside performing current prayers, in order to quickly absolve oneself?

The fundamental principle regarding the making up of missed prayers is that they should be performed in the same manner as current prayers, because "qada' (making up) imitates ada' (performance)." It is not permissible to limit oneself to only the pillars (essential components) of the prayer, except when the time for a fard (obligatory) prayer is constrained. For someone who has many missed prayers, it is sufficient for them to make them up at any time, provided that making them up does not result in physical harm or disruption of livelihood. They should continue to do so until they have made up what they owe. If they do not know the exact number of missed prayers, they should make up what they believe is sufficient to cover them. As for devoutness (khushu'), it is not a condition for the validity of the prayer, so one should not delay making up missed prayers in order to attain it.
