Always check the copyright status. For classical texts (author deceased >50 years), they are generally in the public domain. However, specific PDF scans or modern annotated editions may still hold copyright. More importantly, in traditional Islamic scholarship, it is strongly discouraged to simply download a PDF and study complex spiritual texts alone without a qualified teacher ( murshid or ustaz ). The PDF is best used as a supplement to learning. kitab hidayatus salikin pdf
