Dr Aaidh al-Qarni is a prominent Saudi scholar, author, and activist preacher, best known for his popular self-help book Don’t Be Sad. Dr al-Qarni has garnered a substantial following through a preaching career which spans various modes of broadcast media from audio lectures to a comprehensive website, alislamnet. com. He lectures at mosques, colleges, and Islamic institutions, and hosts a popular weekly television show. He was found guilty of plagiarism in 2012 and has since lost some of his standing.
