Are you a scholar man ?? ...Then why you acting like a dumbass ?? ...We have all the proof thats why their is a LAW ...Here Have fun :
The following Reference of Holy Quran Chapter 4 V 65 was revealed when a man was beheaded by the Hazrat Umar (R.A) due to non compliance of judgment given by Holy prophet Mohammad (S.A.W).
Context of Revelation (Chapter 4, V 65):
Al-Hafiz Abu Ishaq Ibrahim bin `Abdur-Rahman bin Ibrahim bin Duhaym recorded that Damrah narrated that two men took their dispute to the Prophet , and he gave a judgment to the benefit of whoever among them had the right. The person who lost the dispute said, “I do not agree.” The other person asked him, “What do you want then” He said, “Let us go to Abu Bakr As-Siddiq.” They went to Abu Bakr and the person who won the dispute said, “We went to the Prophet with our dispute and he issued a decision in my favor.” Abu Bakr said, “Then the decision is that which the Messenger of Allah issued.” The person who lost the dispute still rejected the decision and said, “Let us go to `Umar bin Al-Khattab.” When they went to `Umar, the person who won the dispute said, “We took our dispute to the Prophet and he decided in my favor, but this man refused to submit to the decision.” `Umar bin Al-Khattab asked the second man and he concurred. `Umar went to his house and emerged from it holding aloft his sword. He struck the head of the man who rejected the Prophet’s decision with the sword and killed him. Consequently, Allah revealed, the aforementioned verse.[Context taken from Tafseer Ibn-e-Kathir]
My brother, how do you infer from this verse that if somebody claims to be a prophet should be beheaded?
Kash tum ne khud iss narration ko ghaur se parha hota Phil post ki hoti Hamare liye. That was a case of two men who SELECTED Prophet Mohammad SAW as a moderator so it was by choice and will.
Still when they didn't admit the decision and went to hazrat Abu Bakar, he didn't kill them. He was a patient and wise man and he said that whatever Prophet said was right. Hazrat Umar was known for their strict and hard nature not only before Islam but also after Islam. That is why when he was selected by hazrat Abu Bakar as next Khalifa people made objections on his strictness, this whole can be read in Bukhari and Muslim, both Sahih books. Anyway when they didn't admit the decision Prophet SAW didn't kill them. After that Abu Bakar didn't kill them. But the second man kept questioning and was finally killed by Umar. If we just take your argument, question arises why Prophet SAW Himself and Abu Bakar who was not less than Umar in love for Prophet SAW didn't kill that man.
Moreover, all Big life taking Crimes are either explained in hadood-e-Allah or simply in Quran or/and through Sunat. How could God miss such an important issue in Quran which we believe is the ultimate and most COMPREHENSIVE book of Allah.
In addition there're numerous Sahih Ahadees where Prophet SAW was physically abused and he did not issue and order to kill neither did God bestowed such a verse in Quran. For example, when a badhu peed in mosque or when a bhadu put his blanket in Prophet SAW neck and abused Him SAW or when people used to put trash on Him SAW or when He SAW was stoned so much that His shoes filled with blood or when in the evenings and nights of Hijrat everyone swore to kill Him SAW or that guy who was thought of being ****** misbehaved with the Prophet SAW when Umar was present, or when in Sheb-Abi-Talib He SAW was forced to eat grass and leather, my Prophet never ordered to kill them. God never issued a verdict to kill them and this is the true Sunnat of Our Beloved Prophet Mohammad Sallalahu Alihe Wassalam.
You can not come up with a single direct reference from the book of God or from the whole life of Mohammad SAW, telling that Capital Punishment is the punish of Islam in the cases of blasphemy.
Another perspective is the sanctity of human and all living beings on earth.
