Initially, he too was an oculist at the  Nuri Hospital of Damascus, but afterward he studied medicine with Ibn al-Matran. Physician of the Ayyubids. In 1208, al-Adil, the Sultan of Egypt, told his vizier al-Sahib ibn Shukur, that he was in need of another physician with the equivalent skill of the chief of medicine at the time, Abd al-Aziz al-Sulami. Al-Adil believed that al-Sulami was busy enough serving as physician of the army. Ibn Shukur recommended al-Dakhwar for the post and offered him 30 dinars a month. Al-Dakhwar turned him down, citing that al-Sulami receives 100 dinars a  month and stating "I know my ability in this field and I will not take less!"
