4:93
And whoever kills a believer intentionally then his recompense (is) Hell, abiding forever in it and will fall the wrath (of) Allah on him and He (will) curse him and He has prepared for him a punishment great.
5:95
O you who believe! (Do) not kill the game while you (are in) Ihram. And whoever killed it among you intentionally, then penalty (is) similar (to) what he killed of the cattle, judging it two men, just, among you (as) an offering reaching the Kabah or an expiation - feeding needy people or equivalent (of) that (in) fasting, that he may taste (the) consequence (of) his deed. pardoned Allah what (has) passed, but whoever returned, then will take retribution Allah from him. And Allah (is) All-Mighty, Owner (of) Retribution.
