Author of “al-Murajiat” Abdhulhussain al-Musawi said:
“Although we are convinced that no distortion has taken place in the verses of the Noble Qur’an and that our heavenly Book has not been tampered with in any way, it is by no means clear that the arrangement and recension of the verses is precisely that in which they were revealed. For it is quite possible that the ‘purification verse’ concerning the People of the House was revealed separately and then, when the verses of the Qur’an were being assembled, was placed in the middle of the verses relating to the wives of the Prophet, either in error or deliberately.”
Quote taken from book of Mujtaba Musavi Lari. What kind of conclusion can we get from these words of slave of Hussain?
There is an error in compilation of Quran. And it happen accidentally or deliberately.
