Indeed, the penalty for those who wage war against Allah and His Messenger and s-Quran Verses

5-Surah Al-Maidah ( The Table spread with Food ) 33

Indeed, the penalty for those who wage war against Allah and His Messenger and strive upon earth [to cause] corruption is none but that they be killed or crucified or that their hands and feet be cut off from opposite sides or that they be exiled from the land. That is for them a disgrace in this world; and for them in the Hereafter is a great punishment,

﴿33﴾إِنَّمَا جَزَاءُ الَّذِينَ يُحَارِبُونَ اللَّهَ وَرَسُولَهُ وَيَسْعَوْنَ فِي الْأَرْضِ فَسَادًا أَن يُقَتَّلُوا أَوْ يُصَلَّبُوا أَوْ تُقَطَّعَ أَيْدِيهِمْ وَأَرْجُلُهُم مِّنْ خِلَافٍ أَوْ يُنفَوْا مِنَ الْأَرْضِ ۚ ذَٰلِكَ لَهُمْ خِزْيٌ فِي الدُّنْيَا ۖ وَلَهُمْ فِي الْآخِرَةِ عَذَابٌ عَظِيمٌ

Quran's Tafhim ( explanation)

*55). The 'land' signifies either the country or territory wherein the responsibility of establishing law and order has been undertaken by an Islamic state. The expression 'to wage war against Allah and His Messenger' denotes war against the righteous order established by the Islamic state. It is God's purpose, and it is for this very purpose that God sent His Messengers, that a righteous order of life be established on earth; an order that would provide peace and security to everything found on earth; an order under whose benign shadow humanity would be able to attain its perfection; an order under which the resources of the earth would be exploited in a manner conducive to man's progress and prosperity rather than to his ruin and destruction. If anyone tried to disrupt such an order, whether on a limited scale by committing murder and destruction and robbery and brigandry or on a large scale by attempting to overthrow that order and establish some unrighteous order instead, he would in fact be guilty of waging war against God and His Messenger. All this is not unlike the situation where someone tries to overthrow the established government in a country. Such a person will be convicted of 'waging war against the state' even though his actual action may have been directed against an ordinary policeman in some remote part of the country, and irrespective of how remote the sovereign himself is from him.
*56). These penalties are mentioned here in brief merely to serve as guidelines to either judges or rulers so they may punish each criminal in accordance with the nature of his crime. The real purpose is to indicate that for any of those who live in the Islamic realm to attempt to overthrow the Islamic order is the worst kind of crime, for which any of the highly severe punishments may be imposed.
