Abū Ḥāmid also said: “The chests of the free are tombs for secrets; whoever divulges the secret of rubūbiyya (divine Lordship) falls into unbelief. He even judged that killing a man like al-Hallāj is better than allowing ten others to live, simply because of the words he uttered.
He further related from one of them who said:
‘Lordship has a secret: were it to appear, prophethood would be undone.
Prophethood has a secret: were it unveiled, knowledge would be nullified.
Knowledge has a secret: were it exposed, legal rulings would cease.’
I say: The ‘secret of knowledge’ has already been laid bare to some wretched Sufis; they unraveled the whole order so that, in their eyes, lawful and unlawful alike were abolished.
Ibn Ḥamdīn continued: Al-Ghazālī then said, ‘If the person who voices such claims does not mean to abolish prophethood for the simple-minded, then what he has said is not false—for what is sound does not contradict itself. The truly complete man is the one whose light of gnosis does not extinguish the light of his piety.’
Al-Ghazālī also said about the ʿārif (gnostic): ‘The lights of the Truth are unveiled to him; the encoded, hidden sciences concealed from other creatures are disclosed to him. He comes to grasp the reality of prophethood and the full intent of every expression of the sacred law—of which we perceive only the outward wording, not the inner truth.’
He quoted someone as saying: ‘When you see him at the beginning you will say: “A righteous friend”; when you see him at the end you will say: “A zindiq (heretic).”’ Al-Ghazālī then explained, ‘The name “zindiq” attaches only to one who abandons the obligatory duties, not to one who abandons the supererogatory.’
He went on: ‘The Sufis have turned to sciences gained by divine inspiration, not those acquired by instruction. One of them sits with an empty heart, his whole concern gathered, saying continuously: “Allah, Allah, Allah” (1), emptying his heart and engaging neither in Qur’an recitation nor in writing down hadith.’
He added: ‘When he reaches this stage, he commits himself to seclusion in a dark room and wraps himself up…’
