Ms Pentio Tubo has been overwhelmed by the support from the public.
"We are over the moon. I couldn't believe it when I found out the bill had been paid," she said.
"My husband and I were crying tears of joy when we found out.
"It is amazing that people were able to help us. We didn't expect it at all."
She said other members of the community had also helped the couple by donating groceries and clothing.
Mr Al Fardan said he was delighted to have the opportunity to help a family in need.
"The most enlightening experience is that of giving back to the communities we serve and kindness is a language that the Al Fardan family understands," he said.
