A robe of honour (Arabic: khilʿa or tashrīf) was a term designating rich garments given by medieval and early modern Islamic rulers to subjects as tokens of honour, often as part of a ceremony of appointment to a public post, or as a token of confirmation or acceptance of vassalage of a subordinate ruler. They were usually produced in government factories and decorated with the inscribed bands known as ṭirāz.
