After that, the second verse takes up the description of some of the things declared unlawful by Allah Ta` ala forsaking which really brings His pleasure. The hint given here is that these people were suffering from a twofold ignorance. On the one hand, they deprived themselves of the good things of life Allah had made lawful for them by denying to use them as if they were unlawful - and did so for no reason. Then, on the other hand, there were things genuinely and really unlawful, things the use of which was to result in the wrath of Allah and the punishment of the Hereafter, these they embraced with both arms only to discover that they had embraced what was to be their undoing in the life-to-come. Thus, they were doubly deprived, deprived of the blessings they had in the mortal world and deprived of the blessings they had the chance of having in the Hereafter. After that, says the Qur'an:

إِنَّمَا حَرَّ‌مَ رَ‌بِّيَ الْفَوَاحِشَ مَا ظَهَرَ‌ مِنْهَا وَمَا بَطَنَ وَالْإِثْمَ وَالْبَغْيَ بِغَيْرِ‌ الْحَقِّ وَأَن تُشْرِ‌كُوا بِاللَّـهِ مَا لَمْ يُنَزِّلْ بِهِ سُلْطَانًا وَأَن تَقُولُوا عَلَى اللَّـهِ مَا لَا تَعْلَمُونَ

Say, "My Lord has prohibited only the shameful things, what is apparent from them and what is hidden, and sin and unjust aggression, and that you associate with Allah something for which He has not sent any authority, and that you say about Allah what you do not know - 33.

In the detail given above, the word: اِثم (ithm : sin) covers all sins which fall on one personally - and in: بَغیَ ; (baghy : injustice) included there are sins which relate to rights and dealings as concerning others. Then come Shirk, the associating of partners with Allah, and the forging of lies against Him. That they are grave sins is quite evident.

This particular detail was mentioned here also because it covers almost all kinds of prohibitions and sins - whether they pertained to belief or conduct, or were done personally, or related to rights of others which were usurped. This was done also because these people of the Jahiliyyah were involved with all these crimes and prohibitions. Thus, exposed here was another demonstration of their ignorance which was that they would abstain from what was made lawful for them and would not even hesitate to use what was declared to be unlawful.

Unfortunately, it is a necessary outcome of excess (ghuluww) in religion and introduction of self-invented practices (bid` at) in it that people who get involved with this type of activity become habitually heedless to the root of religion and its essential requirements. Therefore, the Haram caused by excess in religion and innovation in established faith is twofold. First of all getting involved with such Ghuluww and Bid'ah is a sin in itself. Then, seen in contrast, far too grave is the very deprivation from the true religion of Allah and the genuine way of the Holy Prophet ﷺ .Refuge with Allah (from such a fate) !
