One of the mashaikh relates:

"I saw one of our pious predecessors in a dream.
He had a crown on his head and was clothed in beautiful white garments.
I asked him, 'What is the explanation behind your clothing?'
He replied, 'I am being honored for my obedience'.
I inquired further, 'And the crown?'
He stated, 'I am being honored for my knowledge'."
