(31) And do not kill your children for fear of poverty. We provide for them and for you. Indeed, their killing is ever a great sin.
I asked the Messenger of Allah (PBUH): Which sin is the greatest? He said: To make a rival to Allah, though he created you. I said: Then what? He said: Then to kill your son for fear that he will eat your food. I said: Then what? He said: To commit adultery with your neighbor’s wife.
