I didn't want to bring shia-sunni debate in here, but if Shia Believes in the verses posted by SOA, then the incident of Qalm & Qartaas, will be left with no basis, and as many knows this incident have major role in Shia Religion.
So they along with many others, still argue against the reality that Prophet (SAAW) did actualy knew reading and writing.
Believe me get the proof i will believe your words, it is as simple as that. When you claim something please bring it along with the proof, i will be very glad.
If possible send a PM.
