He would speak about the flaws that undermine deeds, about sincerity, and about scrupulous piety. He had subjected his own soul to many kinds of spiritual struggle, practiced most trades and crafts in order to earn what was lawful, and was gifted with spiritual unveiling.
It is related from him that he said: “When Allah loves a servant, He turns the servant’s chief concern to what he has neglected; but when He dislikes a servant, He turns his chief concern to what has already been allotted to him.”
He also said: “Knowledge is a clear highway; but if you seek it for other than Allah, it becomes evidence against you.”
It was said that he used to accept votive offerings but later abandoned that practice because of the Prophet’s ﷺ statement, “A vow is only extracted from the miser.” (1) After that he came to live on what he was shown in dreams. (2)
Al-Mubārak ibn Kāmil said: “The gnostic, the scrupulously pious man whose speech overflowed with wisdom, Ḥammād, died in the year 525 AH. I have never seen anyone like him. At times he dressed like the wealthy, and at other times like the poor.”
Ibn al-Jawzī (3) said: “He practiced Sufism, claimed gnosis, unveiling, and the sciences of the inner realm, yet he was stripped of knowledge of the Sacred Law. He gained currency among the ignorant. Ibn ʿAqīl used to drive people away from him, and when he learned that Ḥammād would give a feverish patient a single almond and a raisin claiming it would cure him, he sent word: ‘If you do this again, I will strike off your head.’ He died in Ramadan.”
