Ali of Herat

Despite his namesake, wikipedia reports that Ali of Herat (aka Abū al-Ḥasan ʻAlī ibn Abū Bakr al-Harawī - died 1215 CE) was born in Mosul. But, his family was Persian and from Herat. Ali travelled the Islamic world, was the first known graffiti artist of the Muslim world writing many inscriptions (wikipedia), and, according to wikipedia, wrote several books including:

• Kitab al-ishara ila ma`rifat al-ziyara (Book of indications to make known the places of visitations)
• Kitab al-khutab al-Harawia (Book of sermons by al-Harawi)
• al-Tadhkira al-Harawiya fi al-hiyal al-harabiya (al-Harawi's admonition regarding war stratagems)

Ali died in Aleppo; supposedly in a fort built for him by Saladin's son (wikipedia).
