Among the burning questions 73-year-old Kamarmahtum Abdul Wahab asked her long lost sister, Siti Aishah Abdul Wahab when they finally met on Thursday night was whether she was still a practicing muslim.

However, though Siti Aishah did answer her, the true answer remains uncertain.

"She told me already, but really it is between her and Allah, only god knows,” Kamarmahtum told reporters after touching down at KLIA earlier today.

Kamarmahtum, who was swarmed by the media at the airport, also said that her estranged sister’s decision on whether to return home or stay in England can only be her own.

She expressed that the emotional one and half hour meeting between the two would be the ‘last’ effort the family makes to attempt to persuade the latter to come back to Malaysia.

“She said that she regarded herself as being very needed there, and if she returns to Malaysia it is solely for the family," said Kamarmahtum, who said her sister denied being held as a 'slave' as was being previously reported.

“I also would not persuade her to come back (anymore). At first I thought she has passed away but now we know she is well and now knows what we felt (all these years),” she said.

Kamarmahtum arrived from a flight from Heathrow, London, at about 7.40am with former student activist Hishamuddin Rais.

Siti Aishah, from Jelebu, Negeri Sembilan, left Malaysia in 1968 to further her studies at the London School of Economics in United Kingdom.

However, while she was there, Siti Aishah is said to be hugely influenced by the Maoist movement and ‘extreme’ political activities and abandoned her academics.
