It has been authentically reported in Sunni and Shia books, that the pious Caliph Ali ibn Abi Talib punished some of the extemists from among the renegades and heretics (prototype-Rafidi i.e. Sabaites) of his time by burning them with fire. However, did you know that Ali advised Omar (ibn Al-Khattab) to behead sodomites (“homosexuals”) and then burn their corpses?!

The following sources are are all authentic and accepted by Shia scholars, yet we see some ignorants in our time having the audacity to claimย that only the “evil” Sahabah, the likes Abu Bakr, Khalid Ibn Al-Walid etc. did “cruel” things like beheading, burning and that thus Sunnism is violent and dangerous by by its nature whereas Shi’ism is not.

Translation of Hadith no. 2 on page 103 (left side of the scan):
[…] I heard Abu ‘Abdillah (Ja’far Al-Sadiq) saying: “Two sodomites (“homosexuals”) were caught during the reign of ‘Omar (Al-Faruq), one of them fled, the other one was caught and brought to Omar who consulted the people asking them what to do with him (i.e. captured sodomite). A group of people made some suggestions (i.e. as to how he should get executed), then ‘Omar consulted Abu Al-Hassan (‘Ali ibn Abi Talib), who said: “Strike off his neck (behead him)!” ‘Omar then stroke his (i.e. sodomites) neck and was about to carry him (i.e. in order for him to get buried) but ‘Ali said: “Leave it! There is still something left of his punishment.” ‘Omar asked: “And what is left of it?” ‘Ali called for wood (to build a fire) so ‘Omar brought it, then the Chief of the Believer (‘Ali) ordered the burning (of the sodomite’s corpse). [Maladh Al-Akhyar fi Fahm Tahthib Al-Ahkam by Muhammad Baqir Al-Majlisi, vol. 16, page 102-103]

ย He (Zayn Al-Din Al-‘Amili, known as “Al-Shahid Al-Thani”, a descendant of Al-Hilli) says in his Masalik [Al-Afham]: “Our Mathhab states that the oneย who does the action (i.e. sodomy, anal intercourse between two men) of the people of Lut is to be killed without any doubt. The Imam can choose between theย methods [of execution/killing] of: The Sword (i.e. beheading); Throwing (the sodomite) from the top of a high tower/building or he can choose to burn him. And our narrations state with details that in case of a married man, he should be stoned to death and a non-married one should be whipped […]”
The same hadith can be found in other authentic Shia sources such as:
Al-Istibsar by Al-Tusi, vol. 4, p. 219
and in Kulayni’s Al-Kafi,ย vol. 7, p. 199
Al-Majlisi authenticated one of the narrations in his Mir’at Al-‘Uqul:
ู…ุฑุงุฉ ุงู„ุนู‚ูˆู„ ุตุญูŠุญ
And of course in Tusi’s Tahdhib Al-Ahkam, vol. 10, p. 52 (that was authenticated by Al-Majlisi in the first scan).

Lessons to be learnt:ย 
  • Ali and Omar were mutual friends advising and correcting each other.
  • Omar respected Ali, an usurper would never respect, let alone seek advise from an alleged semi-devine rival in the midst of the people.
  • Omar listened to Ali when it came to a trivial matter (execution of a sodomite), if ‘Ali really had the sole right to rule over the Muslims then nothing would have prevented a genuine man like Omar to listen and obey ‘Ali.
  • Beheadings were practiced by the Sahabah/Ahl Al-Bayt, in fact ‘Ali was much more eager than ‘Omar when it came to beheadings as it was him (i.e. ‘Ali) who advised ‘Omar to behead an (“homosexuals”) and burn his corpse something ‘Omar didn’t come up with.
Besides: Shouldn’t ‘Ali still be traumatised by the mere thought of woods that allegedly burnt down the door of “Fatimah’s house” by the “evil” ‘Omar? Instead ‘Ali asks this very’ Omar to bring wood and (yet again?) burn someone. The sheer irony here makes one chuckle.
Shias are literally sitting in a big glass house (or Husseiniyyah if you like), they better don’t throw with stones i.e. repeating nonsensical and unacademical statements such as “Sunnis Godfathers such as Abu Bakr, Khalid and all these evil Sahabah are the roots of Isis and terrorism, beheadings and burning etc …” and what not, when it is clearly proven based on their own sahih narrations and legal fiqh rules of capital punishments that “homosexuals” are not just to be beheaded but on top of it burnt!
It should be noted that the Twelver Shias are bound to the opinion of “their” first “infallible” Imam as the deeds of all Imams are absolute proof and binding in Shi’ism, whereas in Sunni Islam there is no such concept and exaggeration with any companion. This is why one can find Sunni scholars disagreeing with the position of ‘Ali ibn Abi Talib, Abu Bakr and other Sahabah and side with the position that the burning of any human being under any circumstances is absolutely forbidden and that the Sahabah who did this (like ‘Ali) had their own interpretation of texts and are excused (in fact in Abu Bakr’s case not a single narration is authentic with regards to him burning apostates).
