فَاسْتَقِمْ كَمَا أُمِرْتَ وَمَن تَابَ مَعَكَ وَلَا تَطْغَوْا إِنَّهُ بِمَا تَعْمَلُونَ بَصِيرٌ ١١٢

تَطْغَوْا taṭghaw · transgress

So remain on a right course as you have been commanded, [you] and those who have turned back with you [to Allāh], and do not transgress. Indeed, He is Seeing of what you do. (Surah Hud, 11:112)

اذْهَبْ إِلَىٰ فِرْعَوْنَ إِنَّهُ طَغَىٰ ٢٤

طَغَىٰ ṭaghā · (has) transgressed

Go to Pharaoh. Indeed, he has transgressed [i.e., tyrannized]." (Surah Taha, 20:24)

اللَّهُ يَسْتَهْزِئُ بِهِمْ وَيَمُدُّهُمْ فِي طُغْيَانِهِمْ يَعْمَهُونَ ١٥

طُغْيَانِهِمْ ṭugh'yānihim · their transgression

[But] Allāh mocks them and prolongs them in their transgression [while] they wander blindly. (Surah Al-Baqarah, 2:15)

لَا إِكْرَاهَ فِي الدِّينِ قَد تَّبَيَّنَ الرُّشْدُ مِنَ الْغَيِّ فَمَن يَكْفُرْ بِالطَّاغُوتِ وَيُؤْمِن بِاللَّهِ فَقَدِ اسْتَمْسَكَ بِالْعُرْوَةِ الْوُثْقَىٰ لَا انفِصَامَ لَهَا وَاللَّهُ سَمِيعٌ عَلِيمٌ ٢٥٦

بِالطَّاغُوتِ bil-ṭāghūti · in false deities

There shall be no compulsion in [acceptance of] the religion. The right course has become distinct from the wrong. So whoever disbelieves in ṭāghūt and believes in Allāh has grasped the most trustworthy handhold with no break in it. And Allāh is Hearing and Knowing. (Surah Al-Baqarah, 2:256)

His [devil] companion will say, "Our Lord, I did not make him transgress, but he [himself] was in extreme error." (Surah Qaf, 50:27)
