Abdullah Hassan, a 2-year-old, who was the only son of his parents, was in intensive care just as his Yemeni mother got a visa to see him for the last time before his death.
According to the Council on American Islamic Relations, the son died Friday at UCSF Benioff Hospital in Oakland, California.
The father, Ali Hassan, and his son Abdullah, two US citizens, traveled to the United States on October 1, seeking treatment for the boy's genetic brain disease. The mother, Shaima Swileh, was banned from traveling to the United States under the White House's travel ban. after the father's public appeal to President Donald Trump to speed up the processing of his wife's visa application, the US State Department granted Shaima a visa last week.
Abdullah had been ventilated at the children's hospital for over a month.
"We are heartbroken, we had to say goodbye to our baby, the light of our lives," Hassan said. "We want to thank everyone for your love and support at this difficult time, and we ask that you keep Abdullah and our family in your thoughts and prayers."
Abdullah's funeral will be held Saturday afternoon in Lodi, California.
