al-Imaam al-Bukhari, may ALLAH have mercy on him, wrote in his Saheeh,
عن أبي هريرة رضي الله عنه قال: بعثنا رسول الله صلى الله عليه وسلم في بعث فقال: "إن وجدتم فلانًا وفلانًا" لرجلين من قريش سماهما "فأحرقوهما بالنار" ثم قال رسول الله صلى الله عليه وسلم حين أردنا الخروج: "إني كنت أمرتكم أن تحرقوا فلانًا وفلانًا، وإن النار لا يعذب بها إلا الله، فإن وجدتموهما فاقتلوهما" رواه البخاري))
Abu Hurairah (May Allah be pleased with him) said "The Messenger of Allah (ﷺ) sent us on an expedition and said to us, 'If you find so- and-so (he named two persons belonging to the Quraish) commit them to the fire.' When we were on the verge of departure, he said to us, 'I ordered you to burn so-and-so, but it is Allah Alone Who punishes with the fire. So if you find them put them to death.' " (Al- Bukhari, Book 18, Hadith 1609).
It is for ALLAH alone to punish or strike with fire. The people who have declared themselves as the Islamic state, for all of the Muslims in the world to pledge their faithful support to do not have knowledge of this in their judicial system? Let the world finally be aware that these people are not representing the orders of ALLAH. The prophet peace be upon him said about them.
