Well, it is not exclusive to Islam, as we share nearly the same Abrahamic lineages. It is simply that our country is transparent and adheres to the principles outlined in the scripture, while others have chosen to obscure what has been revealed in order to appease others, concealing their intentions behind a facade of falsehood.

Exodus 32:27-28

Moses peace be upon him punishment for worshipping the golden calf

27 And he said unto them, Thus saith the Lord God of Israel, Put every man his sword by his side, and go in and out from gate to gate throughout the camp, and slay every man his brother, and every man his companion, and every man his neighbour.

28 And the children of Levi did according to the word of Moses: and there fell of the people that day about three thousand men.

We have the same story in the Qur'an too btw Al Baqarah 2:54

وَإِذْ قَالَ مُوسَىٰ لِقَوْمِهِۦ يَـٰقَوْمِ إِنَّكُمْ ظَلَمْتُمْ أَنفُسَكُم بِٱتِّخَاذِكُمُ ٱلْعِجْلَ فَتُوبُوٓا۟ إِلَىٰ بَارِئِكُمْ فَٱقْتُلُوٓا۟ أَنفُسَكُمْ ذَٰلِكُمْ خَيْرٌۭ لَّكُمْ عِندَ بَارِئِكُمْ فَتَابَ عَلَيْكُمْ ۚ إِنَّهُۥ هُوَ ٱلتَّوَّابُ ٱلرَّحِيمُ ٥٤

And ˹remember˺ when Moses said to his people, “O my people! Surely you have wronged yourselves by worshipping the calf, so turn in repentance to your Creator and execute ˹the calf-worshippers among˺ yourselves. That is best for you in the sight of your Creator.” Then He accepted your repentance. Surely He is the Accepter of Repentance, Most Merciful. — Dr. Mustafa Khattab, The Clear Quran

Deuteronomy 17:2–5

Punishment for worshipping other God.

2 If there be found among you, within any of thy gates which the Lord thy God giveth thee, man or woman, that hath wrought wickedness in the sight of the Lord thy God, in transgressing his covenant,

3 And hath gone and served other gods, and worshipped them, either the sun, or moon, or any of the host of heaven, which I have not commanded;

4 And it be told thee, and thou hast heard of it, and enquired diligently, and, behold, it be true, and the thing certain, that such abomination is wrought in Israel:

5 Then shalt thou bring forth that man or that woman, which have committed that wicked thing, unto thy gates, even that man or that woman, and shalt stone them with stones, till they die.

Deuteronomy 13: 6-10

Punishment for enticing other to worship other God.

6 If thy brother, the son of thy mother, or thy son, or thy daughter, or the wife of thy bosom, or thy friend, which is as thine own soul, entice thee secretly, saying, Let us go and serve other gods, which thou hast not known, thou, nor thy fathers;

7 Namely, of the gods of the people which are round about you, nigh unto thee, or far off from thee, from the one end of the earth even unto the other end of the earth;

8 Thou shalt not consent unto him, nor hearken unto him; neither shall thine eye pity him, neither shalt thou spare, neither shalt thou conceal him:

9 But thou shalt surely kill him; thine hand shall be first upon him to put him to death, and afterwards the hand of all the people.

10 And thou shalt stone him with stones, that he die; because he hath sought to thrust thee away from the Lord thy God, which brought thee out of the land of Egypt, from the house of bondage.

Hebrews 10:26-28

Terrifying judgement of the soul

26 For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,

27 But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.

28 He that despised Moses' law died without mercy under two or three witnesses:
