You served Islam, Muslims and the Aligarh Muslim University community in India as a student leader.
After that, you served Islam, Muslims and the world as a doctor and a surgeon overseas.
Now you have returned to serve Islam, Muslims and the community -- and the great land and people of India -- upon your retirement in every way you can -- as a doctor, as a leader, as a citizen and in every other way.
If life does not stop, until death that is, nor does service to Allah in Heaven or service to Allah's people -- all people -- right here on earth.
I know full well that in Islam there is no such thing as "retirement."
I don't know anything about either Hazrat Ibrahim, Alaihis Salam, or Prophet Muhammad, Sallallahu Alaihi wa Sallam, ever talking about "retirement."
Nor did, to my knowledge, either one them actually "retire" from active and vigorous engagement with Islam, Muslims and the world, at any point in their life.
You are an example for all Aligarians to admire, emulate and celebrate. Allah bless you and keep you happy and healthy.
