 In 1228, the new Caliph sent the ambassador back to Delhi with robes of honour, recognizing Iltutmish's authority in India and conferring on him the titles "Yamin Khalifat Allah" ("Right Hand of the God's Deputy") and "Nasir Amir al-Mu'minin" ("Auxiliary of the Commander of the Faithful").On 18 February 1229, the embassy arrived in Delhi with a deed of investiture.Although the Caliphate's status as a pan-Islamic institution had been declining, the Caliph's recognition was seen as a religious and political legitimization of Iltutmish's status as an independent ruler rather than a Ghurid subordinate.
