‎السلام عليكم ورحمة الله وبركاته ‎أحسن الله إليكم شيخنا الحبيب، لعلك بخير I hear many people talking about Fyodor Dostoevsky's writings and I am interested. Is it permissible to read from writings like this?

I would say read what is actually beneficial to you. If seeking knowledge does not occupy a lot of your time, then of course what takes precedence is the books of Islamic knowledge. But if they already occupy a lot of your time and you are looking for something else to read a little bit during the day, basically to read for fun and benefit, then there are some books that are very beneficial, whether they are productivity books, business books, or literature books. However, I would research them well and pick them carefully before buying and reading them.
