ʿAbd Allāh ibn Wahb al-Rāsibī (Arabic: عبدالله بن وهب الراسبي‎; died 17 July 658 AD) was an early leader of the Khārijites. Of the Bajīla tribe, he was a tābiʿī, one who learned the teachings of Islam directly from a ṣaḥāba (companion) of Muḥammad. He prostrated himself in prayer so frequently that he developed calluses on his forehead, leading to the nickname, dhu ʾl-thafināt, "the man with the calluses".
