Intro
As we all know, MGA’s arabic was terrible His arabic was sooo bad that he never led any Salaat in his whole life.  The Ahmadi’s that surrounded him lied about this forever, and are sooooo stubborn, they would rather die then admit to the obvious.  MGA also stuttered terribly, this combined with his terrible pronunciation of Arabic meant that Maulvi Abdul Karim Sialkoti, Noorudin, and Ahsan Amrohi led the salaat at Qadian.  Nonetheless, we have found a new reference which also confirms this data.  It is from Bashir Ahmad Rafiq’s book, “The Afghan Martyrs” (1995), see pages 49-50.  An account by Hadhrat Hakeem Deen Mohammad, in this account, an Arab comes to Qadian, in 1902, while the first martyr of Ahmadiyya (Syed Abdul Latif) is also there and he is amazed that MGA can barely recite arabic properly.  MGA then says that Allah has gifted him with the writing of Arabic, not the reading of it.  However, Syed Abdul Latif was about to physically assault this arab.  So much for being peaceful in Ahmadiyya.

The quote
“””After Maghrib I saw the young man in Masjid Mubarak and I pointed the Promised Messiah (PBUH) out to him. After salutation and shaking hands he sat opposite the Promised Messiah (PBUH). At that time Hadhrat Sahibzada Abdul Lateef was already seated immediately opposite the Promised Messiah (PBUH). After introducing himself, in a somewhat brusque manner the young Arab addressed the Promised Messiah (PB UH), and said, “You claim that you are eloquent in Arabic but you are I unable to pronounce the letters ‘ain’ and ‘qaaf like the Arabs .And you falter in your speech. These impediments detract from your eloquence. Witnessing the gross arrogance and the harsh manner of his address Sahibzada Abdul Lateef lost his cool and in this disposition was about to strike the Arab with his fist when the Promised Messiah (PBUH) caught hold of his hand, put it on his thigh, and put his own hand over it. Then the Promised Messiah (PBUH) said to the Arab, My claim concerning eloquence in the Arabic language relates to written Arabic and I do not claim that I can speak like those whose mother tongue is Arabic. I would therefore suggest that you look through some of my Arabic books which you will find in the guest house. Only then will you be able to assess my proficiency in Arabic. Then he said, “Many earlier sages had foretold that Imam Mahdi would stammer somewhat. Therefore a trace of stammering in my speech is proof of my truth. It Then the Arab guest said, “The companions who sit with you and are influenced by you do not seem to comprehend the measure of respect due to a guest. Had you not caught hold of his clenched fist this gentleman would surely have hit me.” In reply the Promised Messiah (PBUH) said, “Like you this gentleman is also a recent arrival and he belongs to a region i.e. Afghanistan, where the inhabitants are known for getting excited rather quickly. Surely his sentiments sprang directly from his love for me.” At that point of time Hadhrat Moulvi Noor-ud-Deen who was sitting at a distance said, ” Hadhrat Abu Bakar (MAPH) once slapped someone who was rude and irreverent in the presence of the Holy Prophet (PBUH).” With a smile on his lips the Promised Messiah (PBUH) said that here was a discernible resemblance. ”
