The first type is an act that does not fill its whole appointed interval. The five daily prayers are the example: one does not have to keep praying the same obligatory prayer throughout its entire time.
Prayer time has 3 roles:
• Container (Zarf): the prayer is performed inside its appointed window; performing it takes only part of that window.
• Condition (Shart): that prayer is not valid before its prescribed time begins.
• Cause (Sabab): the prescribed time gives rise to the obligation of that prayer; it is not obligatory before that time.
The same time can therefore answer different questions: When is it valid? When does the duty arise? Where does its performance fit?
