The Shi'ah and a mention of their sects

His Eminence the Shaykh: By the grace of Allah, I teach a geography course at the university. One of the students asked me when I was dividing the world's population by religion: that there are islands in the African continent,It is called: the Comoros Islands, where the Shi'ah have spread,So he asked me: Who are the Shi'ah? What are their sects? And do we declare any of these sects disbelievers? So I postponed the question until I could ask you, Your Excellency?The Shaykh: This answer requires elaboration.

The questioner: A brief answer?The Shaykh: A brief answer is not useful; because this issue is serious.
