They make the most takfeer on laypeople but just not secular rulers. MBS/MBZ/Sisi in particular.
Muslim Ruler who prays, fast, and do all the obligatory duties but allows some sinful acts to take place*
Amusee and other khawarij ideological promoters: "Taghut, he a taghut, he a kafir, lets rebels, let's bomb ourselves in heavy populated areas with women, children old, babies and civilians, let us cause a rebellion that will permanently weaken us and make us vulnerable, create the biggest refugee crises in history and make millions of muslims leave the land of Islam to the land of kuffars"
Muslim Ruler in the 7th-10th century, kills a sahabi, says the quran is created, kills bunch of the salaf, invades Mekkah and damages the kaaba*
The scholars of the Salaf:
‘Ismah ibn ‘Isam reported: Imam Ahmad, may Allah have mercy on him, said, “Verily, I supplicate for the ruler to have right direction, guidance, and support, by night and day. I view that as an obligation upon me.”
Source: al-Sunnah li-Abī Bakr al-Khallal 1/83
Ibn Taymiyyah said, “Imam Ahmad supplicated for mercy and forgiveness them as he knew that it was not clear to them that they were denying the Messenger or rejecting what he brought. Rather, they had misinterpretations and were mistaken.”

The Prophet’s saying reported on the authority of Hudhayfa Ibn Al-Yamân رضي الله عنه: “There will be rulers who will not be led by my guidance and will not adopt my tradition. There will be among them men who will have the hearts of devils in the bodies of human beings”. I said: “What should I do O Messenger of Allah, if such time overtook me? He said: “You will listen to the commander and carry out his orders, and even if your back is lashed and your wealth is seized (by force), you should listen and obey”
If these people saw the salaf such as Hasan Al Basri and Ahmad Ibn Hanbal they would be called Madkhalis. Funny thing is Shaykh Rabee Al Madkhali wasn't even the first to warn against the Satanic Brotherhood
