A Victorian man has spoken about the horror of being lashed for blasphemy and spending almost three months in a Saudi Arabian prison after returning home early this morning following an unexpected royal pardon.

Mansor Almaribe, 45, said he believed he would never see his family again after he was found guilty of religious blasphemy and held for weeks on end, unable to contact his family.

The Shepparton man, speaking in Arabic which his son translated, said he only had the clothes on his back and was wearing thongs in the "cold, dirty" prison.

Mr Alamaribe was fed cheese for breakfast and rice every day for lunch, and his medication, for conditions including diabetes, soon ran out.
