What is Dr Zakir Naik doing for establishing the most powerful system asked by a reverted Muslim

“There will be Prophethood for as long as Allah wills it to be, then He will remove it when He wills, then there will be Khilafah on the Prophetic method and it will be for as long as Allah wills, then He will remove it when He wills, then there will be biting Kingship for as long as Allah Wills, then He will remove it when He wills, then there will be oppressive kingship for as long as Allah wills, then he will remove it when He wills, and then there will be Khilafah upon the Prophetic method” and then he remained silent.
(Ahmed)

Sholars explain this hadith in this way: Prophethood as in the beginning of the hadith ended with the death of Muhammad (sal Allahu alaihi wasallam). The next stage was Khilafah Rashida and this was from Abu Bakr Siddiq to Ali ibn Abi Taalib (radi Allahu anhuma). Then the Prophet (sal Allahu alaihi wa sallam) said it would be Mulkan which was the rule of the Banu Umayyah, Banu Abbas and the Khilafah Uthmaniyyah. Then after that, he said it would be dictatorship, i.e. oppressive rule, which we are living under today. The next stage will be Khilafah Rashida once again insha-Allah.
