Hamza chronicled the medieval history of Mount Lebanon. His work was largely based on the chronicle of the Buhturid chronicler Salih ibn Yahya (d. 1435). Ibn Sibat continued the history of Mount Lebanon for the rest of the 15th century through the first years of Ottoman rule, which began in 1516. For the history of his own time, he relied on his personal observations. He is a principal source for the history of the Druze Ma'n dynasty of the Chouf in the closing years of Mamluk rule in the 1490s through 1516 and the first interactions of the Ma'ns and the Buhturids with the Ottoman conquerors. The 17th-century Maronite historian and patriarch Istifan al-Duwayhi and the 19th-century Maronite historian Tannus al-Shidyaq depended mainly on Hamza's chronicle for their histories of non-Maronite Mount Lebanon.
