Diana said she wasn't born Muslim, but when her biological father abandoned her mother, Beatrice Nantale, Mansur Ntatwa adopted her and became her foster father.
Diana didn't reveal the name of her biological father.
"I feel proud being a Muslim," the songstress said while speaking to a group of Muslims to whom she was donating food.
"I have been raised Muslim. And Muslims are very kind people."
She went on: "My mother is called Nantale Beat who was married to a Muganda man. Most of you think I'm a Mushese (Munyakore). Yes, I'm a Mushese-Omuganda.
"The name Hajara was given to me by a man who adopted me and I call him Dad. I learned a lot from that man. I didn't grow up with my biological father. Women know that motherhood is not easy. We raise kids alone... I met a man named Mansur Ntatwa. He is of the Mbogo clan. He loved me like his daughter and raise me in Islamic culture and he gave me the name Hajara though I wasn't born a Muslim.
"He taught me a lot about the world and raised me to become the woman you see today. That's why I know Muslims are loving and kind people. And if it wasn't for Mansur, I would never have gone to school or become who I'm today.
"He loved me like his child, taught me how to love God and turn into a woman that loves people. That's why I'm always involved in anything that has to do with Islam.”
