MGA knew Maulvi Abdul Karim since his days at Sialkot in the early 1860’s. Further, he knew Nooruddin and Mufti Sadiq and worked for Nooruddin as an employee in Jammu. Nonetheless, when he moved to Qadian in 1891, he lived on the 3rd floor with his wife in MGA’s house. Further, I am sure that his wife, as well as Noorudin’s wife and MGA’s wife all ate together and raised their kids together, hence, there seem to be 20 people living in MGA’s house by 1892.
“”””When in May 1899 Maulana Muhammad Ali arrived in Qadian, the Promised Messiah gave him accommodation on the third storey of his own house. The ground floor was for guests, while he and his family occupied the middle storey. This storey was adjacent to the Masjid-i-Mubarak and there was a hatch from one room into this mosque through which Hazrat Mirza sahib used to enter the mosque. On one side of the same floor lived Maulana Nur-ud-Din. It was above his room, on the third storey, that Hazrat Mirza sahib made space for Maulana Muhammad Ali.
He had a room and a small courtyard. There was a stairway in the room which went down to the Promised Messiah’s courtyard and the other door opened into the small courtyard. The door of the small courtyard opened on the roof of the Masjid-i-Mubarak. This roof was used in the summer for maghrib and isha prayers, and it was here also that Hazrat Mirza sahib used to sit for his evening gatherings. Next to his room was Maulana Abdul Karim’s room, and his courtyard was also adjacent to the roof of the Masjid-i-Mubarak. From the courtyard next to Maulana Muhammad Ali’s room there was a little stairway going down into a tiny room, and this place served as his office. It was in there that he produced those invaluable English writings for the magazine the Review of Religions,whose language was so perfect that it was alleged that the Promised Messiah must be keeping an Englishman to do the writing!”””” (See “A Mighty Striving” aka “Mujahid-e-Kabir”, written by Mr. Muhammad Ahmad and Mr. Mumtaz Ahmad Faruqui, english translation by Mrs. Akhtar Aziz and Dr. Zahid Aziz).
MGA and his team planned every single move. They all lived in the same house and hence knew each other closely. They seem to have concocted the business of Ahmadiyya and launched it and thus made lots of money.
