Abu Muhammad Shihab al-Din Ahmad ibn Muhammad ibn Abd Allah ibn Ibrahim also known as Muhammad ibn Arabshah (Arabic: ابن عَرَبْشَاه; 1389–1450), was an Arab^[1] writer and traveller who lived under the reign of Timur (1370–1405).^[2]

He was born and grew up in Damascus. Later when Timur invaded Syria, he moved to Samarkand and later to Transoxiana. He later moved to Edirne and worked in the court of Sultan Mehmed I translating Arabic books to Turkish and Persian. He later returned to Damascus after having been absent from the city for 23 years. Later he moved to Egypt and died there.

The famous Muslim scholar, Abd al-Wahhab ibn Arabshah, was his son.
