Rebecca Chisholm, 24, remains in intensive care at Rashid Hospital with a severe brain injury after falling off a horse.
The distraught family of the former Manchester Metropolitan student faced a huge £60,000 medical bill.
An additional £30,000 was required to book their daughter a flight, the family said.
But the family was thrown a lifeline when United Arab Emirate leader agreed to pay all medical bills until Rebecca is discharged.
“His Highness has offered to pay for all of Becca’s medical costs until she is discharged from Rashid Hospital”
A statement on the family’s GoFundMe – which was initially set-up to help pay the bills, read: His Highness Sheikh Mohammed bin Rashid Al Maktoum, the Vice President and Prime Minister of UAE and Ruler of Dubai, has offered singularly the most generous gift we could ever have wished to receive.
“His Highness has offered to pay for all of Becca’s medical costs until she is discharged from Rashid Hospital.
“We will be forever thankful to him and his country.”
The Nottingham lass tragically suffered multiple skull fractures and a brain injury following the incident which happened just a day before she was due to celebrate her birthday earlier this month.
Rebecca, a primary school teacher who lives and works in the Middle Eastern emirate, is said to have told her mother she thought she was going to die as she lay severely injured.
Ms Chisholm was airlifted to a state-run hospital and twice underwent surgery to stem the bleeding on her brain.
It is thought Rebecca had insurance through the school she worked at but the firm is refusing to cover the costs because the accident happened while riding a horse.
