Al Quran : And kill not your children for fear of poverty. We shall provide for them as well as for you

Bismillahirrahmanirrahim 

Al Quran : And kill not your children for fear of poverty. We shall provide for them as well as for you. Surely, the killing of them is a great sin. 

Al Quran, Surah Al-isra (17) , verse 31 

Narrated Anas bin Malik Radi Allahu Anhu : The Prophet Peace be upon him said, "At every womb Allah appoints an angel who says, 'O Lord! A drop of semen, O Lord! A clot. O Lord! A little lump of flesh." Then if Allah wishes (to complete) its creation, the angel asks, (O Lord!) Will it be a male or female, a wretched or a blessed, and how much will his provision be? And what will his age be?' So all that is written while the child is still in the mother's womb."
