Intro
MGA had many books written about him…most of them are lost by 2016.  I found a few more.

The missing biographies are as follows:
Sheikh Yaqub Ali Torab’s books “Sirat-ul-Nabi”, “Sirat Ahmad”, and “Sirat Masih Maoud”, which were published in 1915 (See Mujadid e Azam by Dr. Basharat Ahmad, the preface).
