Al-Baqara 2:256

There is no compulsion in religion[151]; the truth has been made distinct from falsehood. Whoever rejects Tāghoot [152][i.e., false gods] and believes in Allah, has indeed grasped the strong handhold that never breaks[153]. And Allah is All-Hearing, All-Knowing.

[151] This is a great Islamic principle whereby no one is to be coerced to believe, but it is the duty of the believers to make sure that people know what is right and what is wrong.
[152] False objects of worship, such as devils, idols, stones, sun, stars, angels, saints, graves, rulers, etc.
[153] This verse immediately follows Āyat al-Kursī for good reason, as the previous verse contains clear proofs of the Oneness and Greatness of Allah, which purges Godliness from all that are worshiped besides Allah (Tāghoot).

There shall be no compulsion in [acceptance of] the religion. The right course has become distinct from the wrong. So whoever disbelieves in ṭāghūt[104] and believes in Allāh has grasped the most trustworthy handhold with no break in it. And Allāh is Hearing and Knowing.

[104] False objects of worship, such as idols, heavenly bodies, spirits, human beings, etc.

256. There is no compulsion in religion. Verily, the Right Path has become distinct from the wrong path. Whoever disbelieves in Tâghût [69] and believes in Allâh, then he has grasped the most trustworthy handhold that will never break. And Allâh is All-Hearer, All-Knower.

[69] (V.2:256) الطاغوت هو كل ما عبد من دون الله إلا من لم يرض بعبادته فلا يعتبر طاغوتا The word Tâghût covers a wide range of meanings: It means anything worshipped other than the Real God (Allâh), but the one who does not accept to be worshipped will not be considered as a Tâghût, i.e. all the false deities. It may be Satan, devils, idols, stones, sun, stars, angels, human beings, who were falsely worshipped and taken as Tâghûts Likewise saints, graves, rulers, leaders, etc., are falsely worshipped and wrongly followed. Sometimes "Tâghût" means a false judge who gives a false judgement (see V.4:60). [See Tafsir Ibn Kathir and (V.4:51)].

There is no compulsion in religion. The right direction is henceforth distinct from error. And he who rejecteth false deities and believeth in Allah hath grasped a firm handhold which will never break. Allah is Hearer, Knower.
