Surah 5. Al-Ma'ida
Ayah 33 - 34
33 إِنَّمَا جَزَٰٓؤُا۟ ٱلَّذِينَ يُحَارِبُونَ ٱللَّهَ وَرَسُولَهُۥ وَيَسْعَوْنَ فِى ٱلْأَرْضِ فَسَادًا أَن يُقَتَّلُوٓا۟ أَوْ يُصَلَّبُوٓا۟ أَوْ تُقَطَّعَ أَيْدِيهِمْ وَأَرْجُلُهُم مِّنْ خِلَـٰفٍ أَوْ يُنفَوْا۟ مِنَ ٱلْأَرْضِ ۚ ذَٰلِكَ لَهُمْ خِزْىٌ فِى ٱلدُّنْيَا ۖ وَلَهُمْ فِى ٱلْـَٔاخِرَةِ عَذَابٌ عَظِيمٌ
34 إِلَّا ٱلَّذِينَ تَابُوا۟ مِن قَبْلِ أَن تَقْدِرُوا۟ عَلَيْهِمْ ۖ فَٱعْلَمُوٓا۟ أَنَّ ٱللَّهَ غَفُورٌ رَّحِيمٌ
[33-34] The punishment of those who wage war against Allah and His Messenger and run about to spread mischief in the land55 is this; they should be put to death or crucified or their alternate hands and feet should be cut off, or they should be banished from the land.56 This is the disgrace and ignominy for them in this world and there is in store for them a harsher torment in the Hereafter, except those, who repent before you have power over them for you should know that Allah is Forgiving and Compassionate.57
55Here "the land" refers to that country or. territory in which the maintenance of law and order is the responsibility of the Islamic State and "to wage war against Allah and His Messenger" is to wage war against the righteous system of government established by the Islamic State. As Allah likes that such a system of government should be established, He sent His Messenger to establish an equitable system of government, which should guarantee peace and justice to human beings, animals, trees, vegetation and everything in the earth, which may enable human beings to develop to -the fullest their natural capabilities; which should exploit natural resources of the earth for the true progress and improvement of humanity and not for its destruction. It is obvious that any attempt, big or small, to undermine or overthrow such an established system, is in reality a war against Allah and His Messenger. It does not make any difference whether that mischief is created by criminals and murderers who cause disorder in the settled and peaceful society, or by armed forces who attempt to overthrow the Islamic State and establish some corrupt un-lslamic system instead. And every sovereign treats such a violation directed against his authority or against any of his officials as war against himself.
56An abstract of these alternative punishments has been given so That the judge or the ruler may exercise his discretion and award punishment according to the nature and extent of the crime. The real object is to show that any attempt by any person residing in the Islamic State, to overthrow its government is high treason and a most heinous crime, and that the offender is liable to be awarded any of these capital punishments according to the circumstance.
57This implies that if they have refrained from creating mischief and from making any attempt at overthrowing the righteous system, and have shown by their conduct that they are peace-loving and law-abiding good citizens, none of the above mentioned punishments will be inflicted upon them, even if they might have committed any of the crimes before their repentance. They would, however, be liable to be called to account in a court of law for any offense against any individual, such as murder, theft, etc., but they will not be tried for any previous offense of treason or rebellion or war against Allah and His Messenger.
