Imam Abu Hanifa was once asked by an atheist, "Is there any proof that God exists?".
Abu Hanifa replied, "Forget it. At the moment, I am busy thinking about this ship.People tell me there is a big ship; it contains different goods on board. There is no one to steer it, no one maintaining it. Yet, this ship keeps going back and forth; it even traverses big waves on the oceans; it stops at the locations that it is supposed to stop at; it continues in the direction that it is supposed to head. This ship has no captain and no one planning its trips."
The atheist interrupted and exclaimed, "What kind of strange and silly thought is this? How can any intelligent person think that some thing like this can occur?"
Imam Abu Hanifa said, "I feel sorry about your state. You cannot imagine one ship running without some one looking after its affairs. Yet you think that for this whole world, which runs exactly and precisely, there is no one who looks after it, and no one owns it."
