What is the ruling on seeking knowledge from da'wah (Islamic propagation) websites and forums that hold educational courses? Is this considered among the characteristics of Sufis? And what is your advice to these websites regarding the practice of collective learning?

There is no harm in acquiring knowledge online from those qualified to provide it. This acquisition serves the same purpose as direct oral transmission. We must utilize these modern means to serve the religion and spread knowledge. There is no harm in collective learning, as it is one of the inherited methods of teaching knowledge and has no connection to Sufi collective remembrance (dhikr).
