Surat Al Kahf (87-88)

{قَالَ أَمَّا مَن ظَلَمَ فَسَوْفَ نُعَذِّبُهُ ثُمَّ يُرَدُّ إِلَى رَبِّهِ فَيُعَذِّبُهُ عَذَاباً نُّكْراً} (الكهف: 87)

87- Dhul-Qarnayn said to his counsels and people of opinion: As for those who oppress themselves and insist to be a disbeliever, we shall kill him then he shall return to his lord in the Hereafter to torture him severely.

{وَأَمَّا مَنْ آمَنَ وَعَمِلَ صَالِحاً فَلَهُ جَزَاء الْحُسْنَى وَسَنَقُولُ لَهُ مِنْ أَمْرِنَا يُسْراً} (الكهف : 88)

88- As for those who believed and responded to our call in worshipping Allah alone and did righteously, they shall have a great reward in this world and in the Hereafter, and we shall not burden him in the world with difficult works, but we shall treat him kindly and easily.

The author of Zhilal Al Qur'an (may Allah be merciful with him) said: This is the constitution of good rule. A righteous believer should find dignity and good reward at the ruler, and the aggressive must face torment and harm.

He also added: When the balance of rule is in chaos, the aggressive corrupters become close to the ruler and given priority in the state positions, whereas the righteous workers are cast and fought. Then authority becomes a whip and a means of corruption in the hand of the ruler turning the order of the group into chaos and corruption.
