A Non Muslim person asked question regarding permissibility of trading in Islam. Dr. Zakir answered his question and give his recommendation of permissibility of those shares who indulge in Sharia based business. While he also responded to future trading and told him strictly that’s prohibited in Islam.
I perceived that Dr. Zakir didn’t study Islamic Finance deeply. Otherwise he must tell the questionnaire about riba and its strict prohibition. Not only Future is prohibited but also Option never be allowed in Islam because of Gharar(Uncertainty) involved in it.
