Takfeer

What is takfeer? You can't say kafir to a muslim there are conditions for that which def we normal ppl can't a beautiful ans by Sheikh Asim Al Hakeem.
It is labeling a Muslim as a kafir. People as mentioned in the Quran are either believers or disbelievers; 64:2. There are original disbelievers of kafir such as the Jews and Christians. There are also those who were Muslims and then apostated. When someone labels a Muslim as a kafir, this is as saying he is in hell. In the hadeeth, the Prophet salla Allahu alaihi wa sallam told us about a worshipper who used to advise his sinful brother not to sin. When he didn’t listen to him, he swore that Allah will never forgive him. Allah forgave the sinner and nullified all the worshipper’s good deeds because of that word he said. There is a huge difference between saying that a person committed an act of Kufr (disbelief) and saying that he is a kafir. I may see someone taking the Christians as allies. I would say that this is an act of Kufr but I wouldn’t label that individual as a kafir until the conditions are fulfilled, and I will talk about these conditions later.
