Due process must be respected and former prime minister Najib Razak must not be shamed unless he is proven guilty, said Umno Youth chief Asyraf Wajdi Dusuki.
Asyraf was at the Kuala Lumpur Court Complex to provide support for the Pekan MP.
He said that all this while, Najib had only been put on trial by the media, and not by the court of law.
"Let the court conduct the trial fairly and transparently. We hope he is given justice," he told reporters.
He called on Muslims to uphold the principles taught in religion and laws before stigmatising Najib.
Earlier, Najib arrived at the Kuala Lumpur Court Complex to face charges in connection with the transfer of RM42 million into his private accounts from former 1MDB subsidiary SRC International Sdn Bhd.
Najib was detained at his home in Jalan Langgak Duta, Kuala Lumpur at 2.35pm yesterday and was taken to the Malaysian Anti-Corruption Commission headquarters in Putrajaya.
