My Dear Brothers!
It is my guess that our final and true defence will be the short treatise that is the fruit of Denizli Prison. For the extensive plots hatched against us over the past year, originally due to unfounded suspicions, are the following: they attacked us on baseless pretexts such as founding a Sufi order, establishing a secret society, being a tool of external forces, exploiting religious feelings for political ends, working against the republic, meddling in government and breaching public security.
Thanks be to Allah the Most High, their plans failed. Other than the truths of belief and the Qur’an, study of the hereafter, and working for everlasting bliss, they found nothing, even over such an extensive area, among hundreds of students, in hundreds of treatises, in the letters and books written over a period of eighteen years. They began to seek out anything at all to make a pretext of, in order to conceal their plots.
But I think that in the face of a fearsome, covert atheistic organization which has deceived some leaders of the government, turning them against us, possibly attacking us directly on behalf of absolute disbelief, we were made to write the treatise of The Fruits of Belief, which is as clear as the sun and dispels all doubts and is as firm and unshakeable as a mountain, as the most powerful defence against them and to silence them.
