Mother Rabiya Khatoon and other family members are praying for a miracle.
The 10-year-old twins share an artery that carries blood to their hearts.
Doctors will have to separate their brains where the sisters share a blood drainage vessel.
Farah (right) has two kidneys while Saba has none and will require a kidney transplant.
The girls' father, Mohammad Shakeel Ahmed, owns a restaurant but cannot not afford to pay for their treatment.
Abu Dhabi's crown prince, Mohammed bin Zayed Al-Nahyan, has offered to bear the costs of any surgery.
The twins try and live as normally as they can. They love Bollywood movies and enjoy Hindi film songs.
Conjoined twins are extremely rare, occurring in as few as one in every 200,000 births and most of them are girls.
The sisters underwent a series of tests in the Indian capital before doctors said an operation to separate them was viable.
