Forbidden Things

"Come I will recite what your Rabb has forbidden to you:  not to commit shirk with Him, be kind to your parents, not to kill your children making the excuse of  the inability to support them - We provide sustenance for you and for them - not to commit shameful deeds whether open or secret, and not to kill any soul forbidden by Allah, except for the requirements of justice.  These are the things He commanded you so that you may use reason.  Furthermore your Rabb has forbidden you to go near the property of an orphan except to improve it, until he attains maturity; and has commanded you to give full measure and just weight - We never charge a soul with more than it can bear, and whenever you speak, be just, even if it effects your own relatives, and fulfill your covenant with Allah.  These are the things which He has enjoined on you so that you may be mindful."  Quran, Al-Anam 6: 151-152
