The main difference between a complete and an incomplete Jinaayaat is related to
the period of time during which such an action takes place in everyday life, e.g.
a topee, (headgear), is normally worn from the time one gets ready in the morning
till the time one goes to sleep, a period of approximately 12-18 hours.
If the Muhrim wears such a head-gear for a period in excess of half of this "normal"
time, then the Jinaayaat is complete, otherwise it is incomplete.
