What is the ruling on reading human development books, whether by Muslims or translated from non-Muslims, and is it permissible to benefit from the words of non-Muslims in them, knowing that some of them may contain Sharia violations such as advocating listening to music or watching movies, while most of them deal with topics of success, high aspirations, and patience?

Worldly sciences are required alongside religious sciences, and it is permissible to benefit from the useful knowledge of non-Muslims for Muslims if the intention is sincere and aims for reform and progress. For wisdom is the lost property of the believer. However, human development science is not entirely so; it mixes the beneficial with the erroneous and corrupt, and contains false philosophies, esoteric methods, and perhaps pagan rituals, such as neuro-linguistic programming courses, as explained by Dr. Fawz Kurdi. These mixed sciences should not be consulted except by specialists capable of distinguishing to extract what is beneficial from them for Muslims.
