Lost are those who slay their children, from folly, without knowledge, and forbid food which Allah hath provided for them, inventing (lies) against Allah. They have indeed gone astray and heeded no guidance. Al-An'am 6:140 ⧉
Tafsir:
How misguided such people are, is clear from the fact that many of them thought the savage act of killing one’s own progeny was quite proper. Such misapprehensions deprive people of the clear provisions made by God, so that while fighting over ordinary problems, they overlook matters which are of greater importance, but which might still be understood by the use of common sense.
