In late March of last year I had two weeks of free time, when I got a hold of "Mujahid of the Light: A Manual" by Paulo Coelho and a computer. I wanted to derive benefits for the Mujahiddeen (Resistance Fighters) from this book and I this is why I rewrote most of it, removed some excesses and strengthened all of it with verses (ayats), hadiths and stories from the lives of the disciples.
I wrote it while exclusively hoping for mercy of Allah, for the benefit that the Mujahiddeen will derive from it for themselves and for the Jihad.
