He established Ahmadiyya Book House in Qadian and spent his life serving the Jamaat and the Qadiani Royal Family. The allegations regarding the lewd character of Khalifa Mirza Mehmud also disillusioned him the Ahmadiyya Khilafat. Alongwth Abdur Rehman Masri, he started demanding that Khalifa should declare on oath that these allegations are false and if Khalifa is lying then he should be afflicted with divine punishment. Or else a committee should be constituted to investigate these allegations and present its finding.
Fakhruddin Murtan alikuwa Ahmadiya mwingine mtiifu ambaye alikula kiapo cha utii mikononi mwa Mirza Gulam Ahmadi Kadiyani. Yeye alihama kutoka mji wake wa asili wa Murtan na kwenda Kadiyani. Alianzisha duka la vitabu vya Ahamadiya kule Kadiyani na alitumia maisha yake akiitumikia jumuiya na familia ya Kadiyani. Yale madai kuhusiana na tabiya ya uasherati ya Khalifa Mirza Mahmoud naye pia yalimuondosheya Imani juu ya Ukhalifa wa Ahmadiya. Akiwa pamoja na Abdur Rahman Masri, akaanza kudai kuwa Khalifa atamke kwa kiapo kuwa madai haya ni ya uongo na kwamba kama yeye Khalifa anaongopa basi ashukiwe na adhabu ya Mungu. Au vinginevyo iundwe kamati ya kuchunguza madai haya na kuwasilisha hadharani utafiti wake.
