But Mirza was dumbfounded when in the next 4 years (from 1880-1884) Mirza just kept writing, publishing and posting 4 volumes. He realised that now for the next 50 years all he would do is to write volumes after volumes of Braheen Ahmadiyya and distribute them free, without any hope of financial returns, since he had already accepted advanced payment.
Mirza hakuweza kutimiza ahadi yake licha ya mapesa mengi aliyopokea kutoka kwa Waislamu badala yake kwa muda wa miaka minne(1880-1884) akaandika juzuu 4 tu akielezea Uislamu na kuwatumia watu, baada ya hapo akadhamiria kwa kipindi cha miaka 50 baadaye awe anaandika juzuu baada ya juzuu alizoziita Braheen Ahmadiya akielezea dini yake hiyo mpya na kuzigawa bure baada ya kutangulia kupokea mapesa ya watu. Alisimama kuandika Braheen Ahmadiya baada ya kutoa juzuu nne tu. Licha ya kupata upinzani mkali kutoka kwa wanunuzi, kwa kipindi cha robo karne alichapisha na kuuza vitabu vingine vipatavyo 80.
