Sulayman ibn Abd al-Wahhab

Imam Sulaymān ibn ‘Abd al-Wahhāb at-Tamīmī was an Islamic scholar, Hanbali jurist, and theologian from the Najd region in central Arabia. He was the elder brother of Muhammad ibn Abd al-Wahhab, the founder of the Wahhabi movement, and he was one of the first critics of his brother and the Wahhabi movement. He considered the Wahhabi doctrine a heresy and it is possibly that he was the first to use the word "Wahhabi" to refer to his brother's doctrine in his alleged treatise The Unmistakable Judgment in the Refutation of Muhammad ibn 'Abd al-Wahhab.
