But her satisfaction was not shared by the girl's father, who before the verdict was handed down appeared concerned, saying he does not know what would become of his daughter should Riduan, for whom he had appeared as a defence witness during trial, be found guilty.
"Apa boleh buat lah, saya tidak tahu apa mahu buat lagi (I don't know what else to do)," he told Daily Express.
"I had allowed them to marry as according to my daughter, she and Riduan suka sama suka (fond of each other).
If I had not agreed then in the future there would be problems again."
Riduan, 41, was found guilty by Sessions Court Judge Ummu Khaltom Abd Samad after a protracted 26-day trial which saw 19 witnesses and three defence witnesses testifying before the court.
Ummu fixed next Monday for sentencing to allow time for both the prosecution and defence to hand in their written submissions.
Riduan, who has four children from his first wife, can be jailed up to 20 years and whipped for his crime under Section 376(1) of the Penal Code.
Riduan also faces another three counts of bribing the girl's father with RM5,000 to withdraw the police report lodged against him.
The corruption case is still ongoing with the prosecution team from the Malaysian Anti Corruption Commissioner thus far calling two witnesses.
The trial will resume on Feb 7.
After Ummu delivered the verdict, Riduan who was accompanied by his first wife and daughter as well as his brother looked troubled.
Even before the court sat in the morning, the girl's aunt had already declared that she would be immensely satisfied if Riduan were to be found guilty.
"All my efforts throughout this time would not have been for nothing," she said, adding, "however if he were to be freed, what to do, what is important is that I carried out my responsibilities."
It was the woman who had brought the girl to lodge a rape report on Feb. 18, 2013 at the Inanam police station after she told her what had happened while she was in a car parked by the side of the road near Kionsom Waterfall with Riduan.
Riduan raped the girl between 9am and 10am on Feb. 18, 2013.
Ummu in her ruling said after considering all evidence adduced before her, she found the defence failed to cast reasonable doubt on the case and that the prosecution had proved its case.
Earlier, Deputy Public Prosecutor Raja Zaizul Faridah applied for a written submission on the sentence and also informed the court.
