But there is punishment if you reject a ‘true prophet’ of God. If Hadhrat Mirza Ghulam Ahmad of Qadian :as: is a true prophet of God, and sure he is, then look at these verses and see how Allah warns the disbelievers and ones who do mockery against prophets and who transgress.
However, if he’s not a true prophet then Allah is sufficient to take care of him. It’s not upto people to go around and kill people who believe in someone who is from God. Neither it’s the duty of any government.
**3: 22. Surely, those who deny the signs of ALLAH and seek to slay the Prophets unjustly and seek to slay such men as enjoin equity - announce to them a painful punishment
3: 113. They shall be smitten with abasement wherever they are found unless they are protected by a covenant with ALLAH or by a covenant with men. They have incurred the wrath of ALLAH, and they have been smitten with wretchedness. That is because they rejected the Signs of ALLAH and sought to slay the Prophets unjustly. That is because they rebelled and used to transgress.
3: 182. And surely, ALLAH has heard the utterance of those who said, ALLAH is poor and we are rich.' WE shall record what they have said, and their attempts to slay the Prophets unjustly; and WE shall say, Take ye the punishment of the burning;’

16: 37. And WE did raise among every people a Messenger with the teaching, `Worship ALLAH and shun the Evil one.’ Then among them were some whom ALLAH guided and among them were some who became deserving of ruin.

22: 43. And if they accuse thee of falsehood, even so, before them, the people of Noah and the tribes of Ad and Thamud also accused their prophets of falsehood;
22: 53. Never did WE send a Messenger or a Prophet before thee, but when he sought to attain his object, Satan put obstacles in the way of what he sought after. But ALLAH removes the obstacles that are placed by Satan. Then ALLAH firmly establishes HIS Signs. And ALLAH is All-Knowing, Wise.
