:) I think Ahmadis are talking in a literal sense. They are trying to say that Mirza Ghulam Ahmed was just like the Prophet Muhammad(SAW) in his speech, manners, knowledge and look. audhubillah
Mirza learnt Quran and reading and writing from his father and other teachers while no human taught Our Prophet Muhammad(SAW) how to read and write.
You cannot compare anyone as Holy Prophet Hadhrat Muhammad Mustapha SAW. Promissed Messiah claims that he merely a servant of Holy Prophet SAW.
We all muslims try to follow into his footsteps to become like him. We all strive to something like him. Obviously we can only try.
Do not compare how Holy Prophet SAW read and write with Promissed Messiah (A.S) but if you want to then also tell me how do you compare Holy Prophet (SAW) with Hadhrat Moosa (A.S), Hadhrat Eesa (A.S) etc?
