I refer to the letter No freedom of religion for Muslims .

Islam allows for freedom of faith. In fact freedom of faith is guaranteed by the progressive interpretation of Islam. The Rashidun Caliphs and the Prophet totally advocated religious freedom.

But there were - and will always be - some conditions:

That if one leaves Islam, one should not do so on the grounds that there is something lacking in Islam.

That if one joins a new faith, one should not say anything negative about Islam as a faith/way of life.

That one respects Muhammad as the most perfect human/deva, alongside the Hindu gods and Jesus.

That one recognises the Quran as perfect and flawless.

That one does not condemn any of the Sahabah (companions) of the Prophet.
