A Companion who used to write Quran for the Prophet(pbuh) converted to Christian ایک صحابی جو کاتب وحی ہوا کرتا تھا پھر عیسائی بن گیا

We want to show this narration to our Sunni fellows who believe those people who became Muslims in front of the Prophet, they got the status of Companionship, and everything is all right for them. Some Sunni fellows do not want to listen anything against Moawiya because they think he was KATIB al WAHI, However it is not proven that Moawiya had such designation, even we consider that Moawiya had such designation, then look at the narration in Sahih Muslim about Moawiya.

In this narration, a person who used to write Quran for the Prophet, he left Islam and turned Christian!

Shias believe that it is a great status being Companion of the Prophet. It is more important being follower of The Holy Prophet. Once someone becomes believer, tests and exams start for him/her. It is important to remain faithful until last breathe.
