[4:93] And whoever kills a believer intentionally, his punishment is hell; he shall abide in it, and Allah will send His wrath on him and curse him and prepare for him a painful chastisement.
[5:32] For this reason did We prescribe to the children of Israel that whoever slays a soul, unless it be for manslaughter or for mischief in the land, it is as though he slew all men; and whoever keeps it alive, it is as though he kept alive all men; and certainly Our messengers came to them with clear arguments, but even after that many of them certainly act extravagantly in the land.
[6:140] They are lost indeed who kill their children foolishly without knowledge, and forbid what Allah has given to them forging a lie against Allah; they have indeed gone astray, and they are not the followers of the right course.
[6:151] Say: Come I will recite what your Lord has forbidden to you, (remember) that you do not associate anything with Him and show kindness to your parents, and do not slay your children for (fear of) poverty, We provide for you and for them, and do not draw nigh to indecencies, those of them which are apparent and those which are concealed, and do not kill the soul which Allah has forbidden except for the requirements of justice; this He has enjoined you with that you may understand.
[17:31] And do not kill your children for fear of poverty; We give them sustenance and yourselves (too); surely to kill them is a great wrong.
[17:33] And do not kill any one whom Allah has forbidden, except for a just cause, and whoever is slain unjustly, We have indeed given to his heir authority, so let him not exceed the just limits in slaying; surely he is aided.
