Once upon a time almost every society used to behead ‘sinners’ and criminals. But they stopped beheading as they evolved. Like the countries stop having death penalty as they become civilized. What is the difference between hanging, beheading and lethal injection? Probably lethal injection is the least painless method for execution. Beheading looks scary. It is Muslims who still continue beheading like their ancestors. Will Islamic countries ever abolish death penalty? Islamic countries should abolish death penalty as they claim Allah is most merciful and forgiving. Whenever I read the Quranic verses about killing infidels, I feel my assassins are holding a sharp sword to my throat.

2:191- And kill them wherever you find them, and turn them out from where they have turned you out. And Al-Fitnah is worse than killing. And fight not with them at Al-Masjid-al-Haram, unless they (first) fight you there. But if they attack you, then kill them. Such is the recompense of the disbelievers.

2:193- Fight them until there is no [more] fitnah and [until] worship is [acknowledged to be] for Allah.

5:33- 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 (beheading) or crucified or that their hands and feet be cut off from opposite sides or that they be exiled from the land.

5: 45- And We ordained for them therein a life for a life, an eye for an eye, a nose for a nose, an ear for an ear, a tooth for a tooth, and for wounds is legal retribution.

8:12- [Remember] when your Lord inspired to the angels, “I am with you, so strengthen those who have believed. I will cast terror into the hearts of those who disbelieved, so strike [them] upon the necks and strike from them every fingertip.

8:17— And you did not kill them, but it was Allah who killed them. And you threw not, [O Muhammad], when you threw, but it was Allah who threw that He might test the believers with a good test.

9:29- Fight those who do not believe in Allah or in the Last Day and who do not consider unlawful what Allah and His Messenger have made unlawful and who do not adopt the religion of truth from those who were given the Scripture – [fight] until they give the jizyah willingly while they are humbled.

9:123: O you who believe! Fight those of the disbelievers who are close to you, and let them find harshness in you

47:4- So, when you meet (in fight Jihad in Allah’s Cause), those who disbelieve smite at their necks till when you have killed and wounded many of them, then bind a bond firmly (on them, i.e. take them as captives). Thereafter (is the time) either for generosity (i.e. free them without ransom), or ransom (according to what benefits Islam), until the war lays down its burden. Thus [you are ordered by Allah to continue in carrying out Jihad against the disbelievers till they embrace Islam (i.e. are saved from the punishment in the Hell-fire) or at least come under your protection], but if it had been Allah’s Will, He Himself could certainly have punished them (without you). But (He lets you fight), in order to test you, some with others. But those who are killed in the Way of Allah, He will never let their deeds be lost..
