Prominent Muslim preacher Zamihan Mat Zin has clarified that he did not mention Johor ruler Sultan Ibrahim Sultan Iskandar during his lecture, where he condemned critics of the "Muslim-only" laundrette in Johor.

In a statement today, Zamihan said he never used any words that were inappropriate or seditious during the lecture at the Masjid Diraja Tengku Ampuan Jemaah in Shah Alam last week.

"I am ready to be investigated because I believe in the principle of 'berani kerana benar' (I am brave because I speak the truth) and fear of God," he said.
