Dr. Basharat Ahmad wrote a comprehensive biography on the life of MGA. Its called Mujadid-e-Azam, or the “The Great Mujadid”. He was an old friend of Maulvi Abdul Karim and Noorudin, they all knew each other very well. Anyhow, Dr. Ahmad wrote extensively about MGA’s life in Sialkot, however, he purposely omitted the part about why MGA had to go to Sialkot and take up employment. This is very odd, since he quotes Seeratul-Mahdi by Mirza Bashir Ahmad many times. Anyhow, feel free to read Vol. 1 of Mujadid e Azam and you will see the deception.

All Ahmadis are dishonest. They will do and say anything to clear MGA of wrongdoing. This is simply just another case of that.
