Disbelievers commit Sins and claim that Allah commanded Them to do so!

Mujahid said, "The idolators used to go around the House (Ka`bah) in Tawaf while naked, saying, `We perform Tawaf as our mothers gave birth to us.' The woman would cover her sexual organ with something saying, `Today, some or all of it will appear, but whatever appears from it, I do not allow it (it is not for adultery or for men to enjoy looking at!)."' Allah sent down the Ayah,

وَإِذَا فَعَلُواْ فَـحِشَةً قَالُواْ وَجَدْنَا عَلَيْهَآ ءَابَاءَنَا وَاللَّهُ أَمَرَنَا بِهَا

Said in the second verse was: قُلْ أَمَرَ‌ رَ‌بِّي بِالْقِسْطِ (Say, "My Lord has bid-den me to do justice). Here, the Holy Prophet ﷺ has been asked to tell those ignorant people, who were falsely attributing the justification of their naked Tawaf towards Allah, that Allah always commands justice. The word used here is: اَقِسط (al-qist) which essentially means justice, balance and moderation. At this place, ` al-qist' refers to a conduct which is free of excess or deficiency, that is, which neither falls short, nor exceeds the appointed limits - as is the case with all injunctions of the Shari'ah. Therefore, under this sense of qist' included there are all acts of worship and obedience as well as all general injunctions of the Shari'ah. (Ruh al-Ma'ani)

After having stated the command of justice and moderation, two injunctions of the Shari'ah relevant to their erroneous conduct have been particularly mentioned. These are: وَأَقِيمُوا وُجُوهَكُمْ عِندَ كُلِّ مَسْجِدٍ (and yourself be aright at each occasion of prostration) and: وَادْعُوهُ مُخْلِصِينَ لَهُ الدِّينَ (and pray to Him with pure faith in Him). The first command relates to what one does physically and outwardly. The other belongs to the heart, the spiritual dimension. In the first injunction, the word: مسجِد (Masjid), according to most commentators, appears in the sense of prostration (sajdah, sujud or ‘Ibadah) and it means that one should be aright at the time of every Salah or any other act of worship. It could also mean that one should make an effort and be particular to keep one's orientation straight towards the Qiblah. And being aright or keeping the orientation straight could also mean that one should sub-ordinate everything one says or does to what Allah has commanded, maintaining an orientation and stance that never varies, never dwindles and moves elsewhere. Given this meaning, this injunction will not remain particular for Salah only - instead, it would comprehend all acts of worship, dealings and transactions.
