Medicine, instead of healing, contributes to the disease progression and creates other diseases, including other Cancer. “What comes to you of good is from Allah, but what comes to you of evil, (O man), is from yourself.” (Qur’an, An-Nisa 4:79) When person commits the Sin, a black spot appears on his heart, and if he seeks forgiveness, this black spot is removed, and if he returns to Sin the black spot grows until his heart becomes black and he will be doomed. “Disease is an Expiation of the Sins”, in this book I have described 351 Sins. The Sins involve the Evil Jinn. Demons possess the humans because of the Sins, revenge, desire of control, attraction, Sorcery, Evil Eye, anger, fear and depression. The most frequent Sins: denying or associating partners to Allah, the Creator of all things.Cancer is a Jinn (Demonic) Possession. The anti-Cancer treatment excites the hidden Evil Jinn and the Jinn spread more the disease. Additionally, medicine creates other diseases due to the side effects. Doctors cannot help, cannot remove your Sins and make you sicker and die. “Know for certain that when you break no one will heal you except you.”(Ibn Al-Qayyim) Repentance from the Sins is obligatory. “A trial is not sent down except due to a Sin, and it is not lifted except with repentance.” (Ali Ibn Abi Talib) Demons are afraid of Allah only, our Creator. The Ultimate Cure is within the Qur’an: Ruqyah, Negative Ions and Prophetic Medicine. “Whoever abandons the Qur’an would abandon treating sickness and seeking healing through it.”
