On this Part Shaikh explains about birth control & killing chidren.
**************************************** ****
The child has a right to life. Neither the father nor the mother have the right to take the life of the child, whether a boy or a girl, by killing it or burying it alive, as was done by some Arabs of jahiliyyah. Says Allah Ta'ala: And do not kill your children out of fear of poverty; We shall provide for them and for you. Truly, the killing of them is a great sin. (17:31) ...When the female child who was buried alive is asked for what crime she was killed. (81:8-9)

Whatever the motive for this crime may be, whether economical, such as fear of poverty and lack of provision, or non-economic, such as fear of disgrace in the case of a daughter, Islam absolutely prohibits this savage act which is nothing but premeditated murder and the oppression of a feeble, helpless humabeing. That is why, when the Prophet (peace be on him) was asked, \"What is the greatest sin?\" he replied, 'To ascribe divinity to someone other than Allah, when He is the One Who created you.' 'What next?' he was asked. 'To kill your child out of fear that it will share your food, he replied. (Reported by al-Bukhari and Muslim.)
