Is it true that whoever has no شيخ (spiritual guide), then Satan is their شيخ?

The saying "He who has no sheikh has Satan as his sheikh" is incorrect. A person who gains religious understanding through scholarly circles, listening to lectures, or studying and reflecting on books benefits, and it is not correct to say that Satan is his sheikh. It is better for a person to connect with known scholars to learn directly from them, but if correct knowledge is acquired through any means, then he has done well.
