"Shortest Story" joke

Sardarji happened to participate in a competition, which was about writing the shortest story. The organizers had put a condition that a story must have four ingredients
Viz. Religion, ***, suspense and mystery.
Sardarji's turn came after many attempts by others. Sardarji gave a story, which was just one sentence and read:
"oh god, my wife is going to deliver a child".
Ostensibly amused, the organizers asked the sardarji whether it contained all the four ingredients! !
Sardarji replied affirmatively and gave his explanation as below:
Oh god: religion
My wife: ***
Going to deliver a child: suspense (whether a girl or a boy)
"okay.... But where is the mystery? " asked one of the organizers.
The sardar replied: who is the father? ?
Sardarji was declared the winner for writing the shortest story!
