The logic of piety in the verse “and are certain of the hereafter” (Q.2:4) and the logic of jihād in the verse “but those who strive has He distinguished” (Q.4:95) mark out the lines of the ascending path. Having been assured by the Book of God (Exalted is He) that we have a duty to boldly tackle this obstacle, let us now look to the Prophetic guidance for a practical way (minhāj).
Our way or method (minhāj) is the Prophetic Sunna, as noted by the Companion ‹Abdullāh Ibn ‹Abbās (God be pleased with both of them). The word minhāj can be found in the following ḥadīth: “The Prophetic Mission shall last amongst you so long as God wills, then He shall remove it when He wills. Then there shall be a khilāfa that runs according to the Prophetic method (‹alā minhāj an-nubuwwa), lasting as long as God wills. Then He shall remove it when He wills to do so. Then there shall be a rapacious monarchy
(mulk‹āḍḍ) which shall last amongst you as long as God wills, and then He shall remove it when He wills to do so. Then there shall be a tyrannical rule (mulk jabrī)” – perhaps a reference to the dictatorships which Muslims currently live under – “which shall last amongst you as long as God wills, after which He shall remove it when He wills to do so. Then there shall be another khilāfa that runs according to the Prophetic method.” [Reported by Imam Aḥmad with a chain of transmission going back to the Companion Ḥudhayfa (God be pleased with him).]
Al-Ḥāfiẓ al-‹Irāqī declared the chain to be sound. Therefore, we must believe that another khilāfa will come to pass, no matter how long it takes, no matter how arduous the path to it.
