Imamat Day, also known as Khushali, is celebrated by NizariIsmailiShiʿiMuslims to mark the anniversary of the day that their present (Hazar) Imam Aga Khan V succeeded his predecessor to become the Imam of the Time.[1][2] It is related to the concept of the imamah.
The Aga Khan IV was the 49th Imam of the Ismailis, having succeeded his grandfather, the Aga Khan III on July 11, 1957.[3] His Imamat Day was therefore previously observed annually on July 11.
Recognizing the Imam of the Time is central to Ismailis' faith and belief.[1] Imamat Day provides an occasion to reinforce this and to express gratitude to the Imam who, in keeping with the centuries-old tradition of leadership, provides guidance in matters of faith, and works to improve the quality and security of their lives.[1][3] It is a day to reaffirm their spiritual allegiance to the Imam and renew their commitment to the ethics of their faith.[1]
