The series "Caliphate and Imamate in Islamic Thought" - by the writer and thinker Thaer Salama - Abu Malek - Part 48
The caliphate is the act of something taking the place of something else, and the rule belongs to God Almighty, and God has made it for creation in general, as the Prophet, peace and blessings be upon him, said: "Indeed, the world is sweet and green, and God has made you successors in it, and He sees how you act," narrated by Muslim from Abu Saeed Al-Khudri, in accordance with God's saying: "Then We made you successors in the land after them to see how you act." [Yunus: 14], meaning that you apply God's laws and God's methodology among yourselves and to yourselves in every matter, and the caliphate in particular in the rule, from the ruler who rules according to what God has revealed, as this methodology is what distinguishes between the successor in the land being a corruptor in it, shedding blood, or being a caliph who is protected by that methodology from that error, and in order for the methodology to prevail, it must prevail through a state, not just that individuals adhere to it in a society in which other than that methodology prevails!
