Proselytizing of Muslims by members of other religions is not technically prohibited by federal law, even though Muslims may proselytize. It is however prohibited in 10 of the 13 states (i.e. excepting Penang, Sabah, Sarawak and the Federal Territories) and can lead to lengthy jail sentences and many strokes of the rotan (whipping). Most Christian and a few other religious groups in Malaysia put a standard disclaimer on literature and advertisements stating "For non-Muslims only". In a recent case nine Christians were arrested on charges of wanting to convert some Muslim students at the University Putra Malaysia in Serdang, near Kuala Lumpur.

"Whether I were to preach in brief, Sāriputta, or whether I were to preach in detail, Sāriputta, or whether I were to preach both in brief or in detail, Sāriputta, rare are those who understand." (A I 333, Sāriputtasutta)
