"There is a lot written on the internet about my father. My father, right now, is located in a hospital. He is in critical condition as a result of this virus.
"It impacted his heart because last year he had a surgery there, and right now, they did another surgery. He is in a very difficult situation, very difficult. We are asking Allah that he returns him to us.
"Our learned Islamic scholars are telling us, 'Stay home, and do the holiday prayer. Don't have guests. Don't go yourselves as guests.' It is a very difficult situation."
