Ibn Qayyim al-Jawziyya related from al-Sulami that al-Junayd said: “The truthful seeker (al-murid al-sadiq) has no need for the scholars of knowledge”

“When Allah desires great goodness for the seeker, He makes him flock to the Sufis and prevents him from accompanying those who read books (al-qurra’).
-Ibn Qayyim al-Jawziyya, Madarij al-Salikin (2:366

The Imam of the Two Groups (Sufis and fuqaha), our master al-Junayd was told: “Certain people indulge in wajd or ecstatic behavior, and sway with their bodies.” He replied: “Leave them to their happiness with Allah. They are the ones whose affections have been smashed by the path and whose breasts have been torn apart by effort, and they are unable to bear it. There is no blame on them if they breathe awhile as a remedy for their intense state. If you tasted what they taste, you would excuse their exuberance.”
