Freedom of Belief in the Holy Quran

﴿لَآ إِكۡرَاهَ فِي ٱلدِّينِۖ قَد تَّبَيَّنَ ٱلرُّشۡدُ مِنَ ٱلۡغَيِّۚ فَمَن يَكۡفُرۡ بِٱلطَّٰغُوتِ وَيُؤۡمِنۢ بِٱللَّهِ فَقَدِ ٱسۡتَمۡسَكَ بِٱلۡعُرۡوَةِ ٱلۡوُثۡقَىٰ لَا ٱنفِصَامَ لَهَاۗ وَٱللَّهُ سَمِيعٌ عَلِيمٌ ﴾ [Al-Baqarah: 256]

(256) There shall be no compulsion in [acceptance of] the religion. The right course has become clear from the wrong. So whoever disbelieves in Taghut and believes in Allah has grasped the most trustworthy handhold with no break in it. And Allah is Hearing and Knowing.

Surah: Al-Baqarah - Verse: 256 - Juz: 3 - Page: 42

﴿وَلَوۡ شَآءَ رَبُّكَ لَأٓمَنَ مَن فِي ٱلۡأَرۡضِ كُلُّهُمۡ جَمِيعًاۚ أَفَأَنتَ تُكۡرِهُ ٱلنَّاسَ حَتَّىٰ يَكُونُواْ مُؤۡمِنِينَ ﴾ [Yūnus: 99]

(99) And had your Lord willed, those on earth would have believed - all of them entirely. Then, [O Muhammad], would you compel the people in order that they become believers?

Surah: Yūnus - Verse: 99 - Juz: 11 - Page: 220

﴿وَقُلِ ٱلۡحَقُّ مِن رَّبِّكُمۡۖ فَمَن شَآءَ فَلۡيُؤۡمِن وَمَن شَآءَ فَلۡيَكۡفُرۡۚ إِنَّآ أَعۡتَدۡنَا لِلظَّٰلِمِينَ نَارًا أَحَاطَ بِهِمۡ سُرَادِقُهَاۚ وَإِن يَسۡتَغِيثُواْ يُغَاثُواْ بِمَآءٖ كَٱلۡمُهۡلِ يَشۡوِي ٱلۡوُجُوهَۚ بِئۡسَ ٱلشَّرَابُ وَسَآءَتۡ مُرۡتَفَقًا ﴾ [Al-Kahf: 29]

(29) And say, "The truth is from your Lord, so whoever wills - let him believe; and whoever wills - let him disbelieve." Indeed, We have prepared for the wrongdoers a fire whose walls will surround them. And if they call for relief, they will be relieved with water like murky oil, which scalds [their] faces. Wretched is the drink, and evil is the resting place.

Surah: Al-Kahf - Verse: 29 - Juz: 15 - Page: 297

﴿وَجَٰهِدُواْ فِي ٱللَّهِ حَقَّ جِهَادِهِۦۚ هُوَ ٱجۡتَبَىٰكُمۡ وَمَا جَعَلَ عَلَيۡكُمۡ فِي ٱلدِّينِ مِنۡ حَرَجٖۚ مِّلَّةَ أَبِيكُمۡ إِبۡرَٰهِيمَۚ هُوَ سَمَّىٰكُمُ ٱلۡمُسۡلِمِينَ مِن قَبۡلُ وَفِي هَٰذَا لِيَكُونَ ٱلرَّسُولُ شَهِيدًا عَلَيۡكُمۡ وَتَكُونُواْ شُهَدَآءَ عَلَى ٱلنَّاسِۚ فَأَقِيمُواْ ٱلصَّلَوٰةَ وَءَاتُواْ ٱلزَّكَوٰةَ وَٱعۡتَصِمُواْ بِٱللَّهِ هُوَ مَوۡلَىٰكُمۡۖ فَنِعۡمَ ٱلۡمَوۡلَىٰ وَنِعۡمَ ٱلنَّصِيرُ ﴾ [Al-Ḥajj: 78]

(78) And strive for Allah with the striving due to Him. He has chosen you and has not placed upon you in the religion any difficulty. [It is] the religion of your father, Abraham. Allah named you "Muslims" before [in former scriptures] and in this [revelation] that the Messenger may be a witness over you and you may be witnesses over the people. So establish prayer and give zakah and hold fast to Allah. He is your protector; and excellent is the protector, and excellent is the helper.

Surah: Al-Ḥajj - Verse: 78 - Juz: 17 - Page: 341

﴿وَلَوۡ شَآءَ ٱللَّهُ لَجَعَلَهُمۡ أُمَّةٗ وَٰحِدَةٗ وَلَٰكِن يُدۡخِلُ مَن يَشَآءُ فِي رَحۡمَتِهِۦۚ وَٱلظَّٰلِمُونَ مَا لَهُم مِّن وَلِيّٖ وَلَا نَصِيرٍ ﴾ [Ash-Shūra: 8]

(8) And if Allah willed, He could have made them [of] one religion, but He admits whom He wills into His mercy. And the wrongdoers have not any protector or helper.
