Salam. A post in your website titled "The Muslim Plan for Western Civilization" talks about how Muslims should not seek power, and I do found that there is no explicit verse in The Quran that says for Muslim to establish an Islamic State. Back in my times being in a halaqa, there is a hadith that narrates about The 5 Periods of Era (The Prophetic Era of Muhammad, Caliphate, Mulkan Jabriyan, Mulkan 'Adhan, and Caliphate based on Prophethood). I hope you would explain it to me. Jazakallah.
Alaikumassalam wa rahmatullah,
There is no verse in the Quran that clearly and unequivocally asks Muslims to establish an Islamic state. It also never asks Muslims to seek power. Everything the Quran says about governance is vague and can be interpreted in many ways. Mainstream Muslim thinkers believe that this means that the Quran leaves it to each Muslim community to decide its own governance matters according to whatever works best in their particular time and place. I will be happy to discuss any particular verse you have in mind.
As for the hadith you mentioned, the final part that says “then a caliphate will be established according to the methodology of Prophethood” is narrated by only one person (Ibrāhīm al-Wāsiṭī) whose narrations are matrūk (”abandoned”) meaning they are so unreliable as to be unworthy of being cited. Please see the study (Arabic PDF) on this by the hadith scholar Dr. Salah al-Din al-Idlibi.
So there is no authentic narration (as far as I have heard) that talks about the establishment of a utopian caliphate in the future.
There is a serious problem with hadith narrations where there is a short authentic version and a longer version that someone modified according to their own imagination. For example there is a famous hadith that says Muslims will be divided into 73 sects. This is authentic. But then someone added this to its end: “And all of them will enter the Hellfire except one.” And that completely changed its meaning and turned it into a tool for intolerant groups to claim to possess the truth and claim everyone who disagrees with them will go to Hell (see my article on this hadith).
