And He (the Exalted) said: {And leave what is apparent of sin and what is concealed thereof. Indeed, those who earn sin will be recompensed for what they used to commit.} (Al-An'am 120).

And He (the Exalted) said in Surah al-An'am: {Say, "Come, I will recite what your Lord has prohibited to you. [He commands] that you not associate anything with Him, and to parents, good treatment, and do not kill your children out of poverty; We will provide for you and them. And do not approach immoralities—what is apparent of them and what is concealed. And do not kill the soul which Allah has forbidden [to be killed] except by [legal] right. This has He instructed you that you may use reason. And do not approach the orphan's property except in a way that is best until he reaches maturity. And give full measure and weight with justice..." etc.} (Al-An'am 151-152).
