Response (By Shaykh Rabee’) I will mention some examples for you. The likes of this happend to Ibn Aqil, Al-Bayhaqi, Al-Harawi, and many others throughout Islamic History. Many people throughout history were enticed by the knowledge they have, so they sat with the people of innovation and desires, leading them to lost (I.e. Deviation). In this are many lessons and admonitions. This occurred to people that once followed the way of the Salaf, but because they sat with the people of innovation, mixed with them, and read the books of the people of falsehood, they deviated and got lost. So my advice for these individuals is to benefit from their brothers, and before that to benefit from the great Manhaj which encourages you to be safe from all deviance and misguidance, and protected from all evil. By Allaah, nothing is equal to safety from misguidance and trials.
