Chief Adviser Prof Muhammad Yunus has said Prince Karim Al-Hussaini, Aga Khan IV's visionary leadership and unwavering commitment to people's well-being has been exemplary.

"Over the decades, I had regarded him for his dedication to champion empathy, harmony, pluralism," Dr Yunus said in a condolence message sent to Prince Rahim Aga Khan V who was named 50th hereditary Imam of the Shia Ismaili Muslims on February 5.

Prince Karim Al-Hussaini passed away in Lisbon on February 4, aged 88, surrounded by his family.

Prince Karim Aga Khan was the founder and chairman of the Aga Khan Development Network.

With deep sorrow, the Chief Adviser extended, on behalf of the government and people of Bangladesh, heartfelt condolences on the passing of the Aga Khan IV.

"With great fondness and reverence, I recall my conversations with him and his ideas to uplift livelihoods of communities in diverse parts of the world. I shall cherish my friendship with Aga Khan IV," Dr Yunus said, adding that he had the distinct honour to work with him on the board of his foundation, and had many occasions to visit with him and also have many discussion on issues of common concern and interest at many board meetings and conferences.

"As I had been to the far flung parts of the world, I saw for myself how the initiatives of the Aga Khan Development Network (AKDN) left indelible marks on the ground. His focus on learning and culture, in particular, truly emanated out of his vision to touch souls beyond identities or distinction," Dr Yunus.

In Bangladesh, the Chief Adviser said, they would remember Aga Khan IV for the ways he wished to stand by people, to help them transform minds of the posterity, uphold heritage and support the vulnerable.

In a truly landmark moment for Grameen Bank, Dr Yunus said, the Aga Khan Architectural Award was given for the design of its US$ 500 home for its member/borrowers a bold and visionary decision!

"Many in Bangladesh would hold Aga Khan IV dearly to their hearts for he brought the AKDN to Bangladesh with an expanded Protocol in 2013. The Aga Khan Academy, in the heart of Dhaka City, remains one shining instance of his vision and determination," said the Chief Adviser.

He said the people of Bangladesh would stand ready to build on the valued legacy of His Highness by impactfully translating the provisions of the Protocol.

"In this time of immense grief, we stand in solidarity with you, your family, and the entire Ismaili community around the world. May you draw on the enduring legacy of Aga Khan IV, whose spirit of service and humanity will continue to inspire generations to come, across continents," Dr Yunus said.

"Our thoughts and prayers remain with you and your bereaved family. May the Almighty Allah grant Aga Khan IV eternal peace and your family solace during this most difficult time," said the Chief Adviser.
