"Islamist author Muhammad Qutb (brother of and promoter of Sayyid Qutb) in his influential book "Islam, the misunderstood religion", states that "science is a powerful instrument" to increase human knowledge but has become a "corrupting influence on men's thoughts and feelings" for half the world's population, steering them away from the Right Path.He gives as an example science's denial (he claims) of telepathy when in fact it is documented in hadith that Caliph Umar prevented commander Sariah from being ambushed by communicating with him telepathically.
