Answered by Sayyidi Habib Umar bin Hafiz (may Allah protect him and benefit us by him)
If someone has extreme beliefs and then renounces them, at what point should they be introduced to the Shaykhs of the spiritual path and aspects of Tasawwuf?
They should be introduced to these things according to their aptitude. What is more important is that they are taught the straight path by learning the methodology of the Prophet, the Companions and the pious people of the Ummah. When they have learnt a portion of this, they will be ready to understand the concept of taking the spiritual path at the hands of a shaykh.
