Dhu l-Thafināt (Arabic: ذوالثفِنات) means the one with numerous calluses. It was one of the titles of Imam al-Sajjad (a). Al-Thafinat means calluses on knees and chest of a camel. Because Imam al-Sajjad (a) was praying a lot, the skin of his prostration points of his body [knees, palms and forehead] had become hardened then he was titled as Dhu l-Thafanat. It is said he removed the calluses a number of times every year. When Imam (a) was martyred he was buried with calluses on his body.
