Surah An Nisaa, verse 93,
"Whoever kills a believer intentionally - his recompense is Hell, wherein he will abide eternally, and Allah has become angry with him and has cursed him and has prepared for him a great punishment."
(4:93)
Displaying the characteristics of a bot, you have not surprised me with your two links that have nothing to do with the topic. As for the verse, the stipulation for Hell is that if you kill a believer
intentionally. Khalid ibn Waleed (ra) presented his case for killing Malik bin Nuwayrah which was far from intentional killing of an innocent believer. By the way, who said Malik was a believer? Refusing to pay Zakah is apostasy, punishable by death, even according to Shi'i narrations.
Here are three narrations from Al-Kafi declaring those who refuse to pay Zakah as apostates:
‘Ali ibn Ibrahim from his father from Isma’il ibn Marrar fromYunus from Ibn Muskan … on the authority of Abu Ja’far (Muhammad ibn ‘Ali Al-Baqir): “The Messenger of Allah addressed a group of people in the mosque telling some of them to get up [of the mosque] until he threw out five persons, then he said: “Get out of our mosque and do not pray in here whilst you haven’t paid your Zakah.” [Al Kafi vol. 3 – The Book Of Zakah ch. 2]
Yunus from ‘Ali ibn Abi Hamzah from Abu Basir on the authority of Abu ‘Abdillah (Al-Sadiq), who said: “We refuses to pay even a single ounce of the Zakah is not a believer nor a Muslim and this is the statement of Him (Allah), may He be glorified and exalted […].” [Al-Kafi vol. 3 – The Book Of Zakah ch. 2]
Abu ‘Ali Al-Ash’ari, from the one who mentioned it, from Hafs ibn ‘Omar, from Salim, from Abu Basir, (It has been narrated) from Abu ‘Abdullah (Al-Sadiq), who said: “Whoever refuses to pay a carat of Zakat, let him choose to die as a Jew or a Christian (i.e. kafir).” [Al-Kafi vol. 3 – The Book Of Zakah ch. 2]
And what is the punishment for refusing to pay Zakah?....from Sahl from ibn Shamun from Al-Asam from Malikk ibn ‘Utbah from Ibn Taghlub who said: “Abu Abdullah (i.e. Al-Sadiq) told me: “Allah has declared the blood of two types of people permissible to be shed in Islam, nobody must judge with regards to these two types until Allah sends our Qa’im (Shia Mahdi) from Ahl Al-Bayt, and when Allah sends him, he will judge with regards to these two types according to the ruling of Allah, without requiring any testimony, which is: The adulterer will be stoned and
the one who refuses to pay the Zakah will get beheaded.” [Al-Kafi vol. 3 – The Book Of Zakah ch. 2]
