The Lahori-Ahmadis seem to be just as dangerous as the Qadiani-Ahmadis, however, MGA was always a liability and even though they tried to lower MGA’s rank, they still barely got any converts after 1940 and thus withered away into history.  To be fair, they cannot be called non-Muslim per the sharia and and were less fanatical as compared to their Qadiani counterparts. Further, the British had allowed for 1-Qadiani to be heavily involved into politics (zafrullah khan) and 1-Lahori (Naseer Ahmad Faruqi).  Naseer Ahmad Faruqi wrote extensively vs. the Qadianis, his brother Mumtaz Ahmad Faruqi wrote the official auto-biography of Muhammad Ali, who was his father-in-law.  Further, his brother, Mumtaz Ahmad Faruqi accused the Ahmadiyya Khalifa, Mirza Basheer-ud-din Mahmud Ahmad of illicit sexual behavior and called the Khalifa’s death as a miserable death.  Both of these brothers were the sons of Dr. Basharat Ahmad, the famous Lahori-Ahmadi who wrote a huge autobiography on the life of MGA.

Naseer Ahmad Faruqhi was given some major congressional jobs

Faruqi also wrote: 

“In 1946 I was Deputy Commissioner of Karachi. The Governor of the Sindh was Sir Francis Mudie, one of the few British who, being fully aware of the machinations of the Hindus, was a great sympathiser of the Muslims and supporter of the Pakistan cause. As I had previously served as his secretary, he used to tell me his inner feelings, especially as he found me to agree with his views. Even after I became Deputy Commissioner of Karachi he used to have discussions with me in favour of the creation of Pakistan. His support of the Muslims being no secret, the Hindu press used to refer to his name sarcastically, from his initials F.M., as “Fateh Muhammad”, and send telegrams against him to the Viceroy Lord Wavell and the Secretary of State for India Lord Pethick-Lawrence. But Sir Francis Mudie, instead of being overawed or intimidated, was undeterred and used to fight these complaints.A British cabinet mission came to India in 1946, headed by Lord Pethick-Lawrence, to discuss the question of Indian independence, and on their way from London to New Delhi they stayed in Karachi for one night as guests of the Governor of the Sindh. The following morning it was my official duty, as District Magistrate, to be present at Karachi airport for their departure. After they left, the Governor beckoned me to accompany him in his car. As soon as the car moved off, he said to me: “Faruqui, they are not going to give us Pakistan”. This appeared to be the final, irrevocable decision of the British government….”(See: under heading ‘Prediction of creation of Pakistan’).
