Remember, my Muslim brother:
Replacing an unjust Taghut (tyrant) with a just Taghut makes the oppressed, the subjugated, and the people of Imaan happy, just as the Companions رضوان الله عليهم rejoiced at the victory of the Romans over the Persians, two nations of Shirk (polytheism) and Kufr (disbelief).
However the Muwahhid (monotheistic) Muslim, who disbelieves in the Taghut , declares him to be a disbeliever, disowns him, opposes him, declares animosity towards him, and fights him will only truly rejoice when the Islamic State is established upon the path of Prophethood, that implements the Islamic Shari’ah and appoints a Caliph that is obeyed, whether he is righteous or wicked, disobedient or unjust.
The uniqueness of the system of the Islamic State is that any Muslim can and has the right to bring forth a complaint, as a plaintiff to the judiciary of grievances (Qudat Al-Mazalim) against the Caliph or whoever represents him from his ministers and governors.
It is forbidden for the Muslim in the Islamic State to revolt against an unjust Caliph as long as he implements the Shari’ah, unless he (Caliph) manifests disbelief, based on the saying of the Prophet ﷺ , “Obey him even if he flays your back and takes your money...", because in the Shari’ah, precedence is always given to preserving the Deen (religion) over preserving lives and money.
Consider the following narration; 'Ubadah bin As-Samit رضي الله عنه reported:
“We swore allegiance to the Messenger of Allah (ﷺ) to hear and obey; in time of difficulty and in prosperity, in hardship and in ease, to endure being discriminated against and not to dispute about rule with those in power, except in case of evident disbelief regarding which there is a proof from Allah. We swore allegiance to Messenger of Allah (ﷺ) to say what was right wherever we were, and not to fear blame of any blamer. [Bukhari and Muslim].
So, my Muslim brother, be vigilant to distinguish the reality of the current nationalistic revolutions masquerading as Islamic revolutions from the Khilafah system. Allah has obligated the Ummah to rise up against the tyrant who rules by other than what Allah has revealed, whether he is just, a criminal or an aggressor, and to establish the Shari’ah of Allah. Be mindful of the fact that it is Islam that has obligated the Ummah to rise up against the tyrant who attacks with disbelief and injustice and has forbidden the Ummah to rise up against a Caliph, because it is tantamount to rising up against the Shari’ah and the entire Islamic Ummah.
So, it is prohibited to revolt against a Caliph or his representatives with the sword, when we have a complaint against them, unless explicit Kufr (disbelief) is apparent.
So be careful.
