Hammad al-Harrani or Abu al-Thana' Hammad ibn Hibat Allah ibn Hammad ibn al-Fudayl al-Harrani al-Hanbali (Arabic: حماد الحراني ) was a Muslim scholar, poet, merchant and traveler who left his home town Harran to live in Alexandria under the reign of Salah al-Din al-Ayyubi. Both towns were dominated by Hanbali school. However, he came back to Harran and died there in 598 AH/1202 AD. He is the author of a lost history of Harran and compiled poems.
There were many scholars who listened and reported hadiths from Hammad al-Harrani during his stay in Alexandia and after he returned to Harran; among them were Ibn al-Hajib's (570-646 AH) and Ahmad al-Harrani.
