The 75-year-old legend is living in a one-bedroom house in suburban Jogeshwari with her son, who too is unwell.
"She has been unwell for quite sometime. Her daughter passed away last month due to Parkinson's disease. Since then her health has deteriorated," Begum's daughter-in-law Zarina told PTI.
"She (Begum) has breathing problem, weakness and forgets things. She was in ICU and doctors told us her heart has become weak. We must take care of her. So we have brought her home," Zarina said.
Speaking to PTI the singer, however said, "I am okay now."
"No one from the film industry comes ahead to help us financially. We somehow manage the medicine expense, but when we go to hospital it gets difficult," Zarina said.
Begum was the voice behind evergreen hits like "Mujhko Apne Gale Lagaa Lo", "O Mere Humrahi" and "Kabhi Tanhaiyon Mein Yun Hamari Yaad Aayegi" and "Hum Haal-e-dil Sunaenge" among others.
