Sulayman ibn Abd al-Wahhab

Imam Sulaymān ibn ‘Abd al-Wahhāb at-Tamīmī (Arabic: سُليمان بن عبدالوهّاب التميمي) 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 likely 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.

The dispute between them reached the point of confrontation with weapons and fighting, and the Wahhabi historian Hussein ibn Ghannam documented that bloody conflict between the two brothers in his book, which was printed by Abdel Mohsen Aba Bateen in Egypt in 1368 AH. Abdullah bin Abdul Rahman bin Saleh Al Bassam mentions him in his book "Scholars of Najd during eight centuries" in which he says "Sheikh Suleiman is in breach of his brother Sheikh Muhammad and his call and is hostile to it and a response to it."
