Caution is parent of safety!

Think about it...
you are driving in a road. A car is in front of you. Suddenly you see the driver blink.
you should pay attention, and be careful.
In fact you trust on driver. You trust on something he/she said, without conversance. 

Did you see anything?-NO
Do you know what just happened?-NO
So why do you trust him/her?
Because Caution is parent of safety!

So...
From the beginning of Human Civilization somebodies named prophet came and bring some beliefs such as believe on God, Heaven, Hell, devil, and other world and etc. [I don't know your beliefs or something you know. but,] We know they were 124000 prophets. Some of them had prophecy and holy book, such as five of holy prophets: Noah (AS), Abraham(AS), Jesus (AS), Moses(AS), Muhammad(SAW).

All of them did. But question is here:
Caution is parent of safety! Isn't it?

I mean, when they came and warn about something, shouldn't we pay attention?
If at least presume one percent that is Truth; Isn't it that Caution is parent of safety!
