"Mubashar Ahmad Khosa, a well known medical practitioner of Mirpur Khas area, was attending to his patients when two unknown assailants entered the clinic and opened fire on him before fleeing the spot on a bike," Jamaat Ahmadiyya Pakistan spokesman Salimuddin said.
He was rushed to a nearby hospital where he was declared brought dead.
Khosa is survived by his wife, two sons and as many daughters.
He was laid to rest in Rabwah, Chiniot district of Punjab province today.

It is alleged that concerned authorities continue to turn a blind eye over such insightful incidents against Pakistan's Ahmadi population, resulting in the killing of innocent people.
"How much longer Ahmadis will have to endure such persecution in the name of religion," Salimuddin asked demanding the perpetrators must be brought to justice.
Police have registered a murder case against unidentified men and are investigating the case further.
Ahmadis are among the most persecuted minorities in Pakistan. They consider themselves Muslim but were declared non-Muslims through a constitutional amendment in 1974. A decade later, they were barred from proselytising or identifying themselves as Muslims.
In 2008, another Ahmadi doctor Abdul Manan Siddiqi was assassinated in a targeted attack but his murderers have still not been convicted.
