﴿ قَالَ يَٰٓـَٔادَمُ أَنۢبِئْهُم بِأَسْمَآئِهِمْ ۖ فَلَمَّآ أَنۢبَأَهُم بِأَسْمَآئِهِمْ قَالَ أَلَمْ أَقُل لَّكُمْ إِنِّىٓ أَعْلَمُ غَيْبَ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ وَأَعْلَمُ مَا تُبْدُونَ وَمَا كُنتُمْ تَكْتُمُونَ ﴾

“Said He: "O Adam, convey unto them the names of these [things]." And as soon as [Adam] had conveyed unto them their names, [God] said: "Did I not say unto you, `Verily, I alone know the hidden reality of the heavens and the earth, and know all that you bring into the open and all. that you would conceal'?"”

Man’s greatest crimes, after the denial of his Lord, are spreading corruption and causing bloodshed in the world. Neither an individual nor a group has God’s permission to indulge in such actions as may disrupt the order of nature established by God. For example, no man should take the life of another: all actions of this nature disqualify mankind from receiving God’s mercy. In short, preserving the system of nature is ‘to reform’ it, while upsetting this system is equal ‘to spreading corruption’.
