Surah 7. Al-A'raf
Ayah 33
٣٣. قُلْ إِنَّمَا حَرَّمَ رَبِّىَ ٱلْفَوَٰحِشَ مَا ظَهَرَ مِنْهَا وَمَا بَطَنَ وَٱلْإِثْمَ وَٱلْبَغْىَ بِغَيْرِ ٱلْحَقِّ وَأَن تُشْرِكُوا۟ بِٱللَّهِ مَا لَمْ يُنَزِّلْ بِهِۦ سُلْطَـٰنًا وَأَن تَقُولُوا۟ عَلَى ٱللَّهِ مَا لَا تَعْلَمُونَ
[33] O Muhammad, say to them, "The things which my Lord has forbidden are: shameful deeds whether open or secret,24 sinful25 things and transgression against the Truth,26 He has also forbidden to associate partners with Allah since He has sent down no authority therefor; (He has also forbidden) to attribute to Allah's name the thing which you know not He has said."
24Please refer to E.N. 128 and E.N. 131 of Al-An'am.
25The literal meaning of "ithm " is negligence. The sense of sin has entered into this word from athimah"which means a she-camel that can run fast but willfully does not do so. Likewise that man who neglects to obey the Commandments of his Lord, in spite of his ability to do so, shall be sinful for he has no intention of pleasing Him.
26It will be rebellion against the Truth, if one transgresses the prescribed limits and enters into the bounds where he has no right. Likewise all such people as transgress the bounds prescribed for the servants of Allah and follow their own will, behave as masters in His Kingdom and encroach on the rights that belong to Allah alone, are really rebels against Allah.
