In 1285 he was present at the assault of a stronghold of the knights of St John, and he took part in the sieges of Tripoli, Acre and Qal'at ar-Rum. In 1298 he entered the service of the Mameluke Sultan Malik al-Nasir and after twelve years was invested by him with the governorship of Hamah. In 1312 he became prince with the title Malik us-Salhn, and in 1320 received the hereditary rank of sultan with the title Malik ul-Mu'ayyad.
For more than twenty years all together he reigned in tranquillity and splendour, devoting himself to the duties of government and to the composition of the works to which he is chiefly indebted for his fame. He was a munificent patron of men of letters, who came in large numbers to his court. He died in 1331.
His chief historical work in An Abridgment of the History at the Human Race, in the form of annals extending from the creation of the world to the year 1329 (Constantinople, 2 vols. 1869).
His geography is, like much of the history, founded on the works of his predecessors, and so ultimately on the work of Ptolemy. A long introduction on various geographical matters is followed by twenty-eight sections dealing in tabular form with the chief towns of the world. After each name are given the longitude, latitude, climate, spelling, and then observations generally taken from earlier authors.
Parts of the work were published and translated as early as 1650 in Europe.
