Why do Muslims argue about who is or isn't Muslim?

Discussing correct and incorrect theological beliefs is not only permissible but necessary — every religion and philosophy must define its own terms. However, there is a critical distinction: judging an action or belief as wrong does not mean pronouncing a verdict on that individual's hereafter. Most people follow the sect they were born into. Non-mainstream Muslim groups that affirm the kalima, fast Ramadan, and face the qiblah are generally within the fold of Islam even if their beliefs are problematic. Groups that deny foundational tenets (like prophethood ending with the Prophet ﷺ) are outside the fold. The application of these principles — how to treat such groups politically and socially — varies by time, place, and cultural context.

The Question — 0:00

Sister Sasha from Pakistan writes: she is Sunni but is deeply distressed by the sectarian situation she sees around her — groups constantly declaring each other kafir and the hatred tearing Pakistani society apart. She asks: why can't we just let people identify as Muslim and let Allah judge them? What can be done about all of this sectarianism?

Why Defining Correct Belief Matters — 1:00

Yasir Qadhi answers on two levels: theoretical (universal) and practical (context-dependent).

Theoretically: every important term must be defined. Legal contracts define every single term precisely because imprecision leads to confusion. "Islam" is far more important than any legal contract term — it is the path to salvation. Therefore, the question of what constitutes authentic Islam is one we are obligated to engage with.

More than that: we will not know what it means to be a good Muslim unless we also study what it means not to be one. The Quran says: "Thus do We explain the signs so that the way of the criminals becomes clear." Understanding the right requires understanding the wrong. Understanding health requires studying disease. This is why the entire field of Islamic theology ('aqida) includes the study of deviant beliefs.

The Critical Distinction: Action vs. Person — 4:00

There is a confusion in modern discourse around the phrase "don't judge me." Every civilization judges actions. Courts prosecute people based on what they do. We judge an alcoholic drink as haram — that doesn't mean we condemn the alcoholic to hellfire. These are two completely different statements.

When Yasir Qadhi says a belief is wrong, he is making a statement about the belief, not pronouncing a verdict on the person's hereafter. He may simultaneously say: "This is an incorrect belief, AND this person deserves my compassion, kindness, and respect as a human being." These two statements are entirely compatible. The failure to make this distinction is a serious problem in much contemporary Islamic preaching.

The Prophet ﷺ gave us a beautiful example: a man who became delirious with joy at the moment he thought he was saved from death blurted out: "O Allah, You are my servant and I am Your lord!" — an obviously theologically problematic statement. The Prophet ﷺ excused him and said he was overwhelmed with joy. Context matters. Individual circumstances matter. Emotional states matter.

Non-Mainstream Muslim Groups — 8:00

Yasir Qadhi addresses the specific groups his correspondent mentions without naming them.

Groups that affirm the kalima, pray toward the qiblah, fast Ramadan, and read the Quran — even if they hold problematic theological positions (such as beliefs about the Sahaba, or special status for certain figures) — are generally within the fold of Islam. Their beliefs may be heterodox, their theology may be problematic, but they are Muslims. The vast majority of such followers were simply born into that tradition and taught what their parents taught them. Is a Sunni any different? Most Sunnis are Sunni because their parents were Sunni.

Yasir Qadhi says: he will disagree with problematic beliefs and politely teach and preach what he considers to be authentic Islam. He will never preach hatred toward such groups or individuals. He respects their humanity without endorsing their beliefs. He will say: "This is an incorrect belief," and still treat that person with courtesy and warmth. These are not mutually exclusive positions.

Groups that deny foundational and universally-known tenets — such as the finality of prophethood, or directing acts of worship to other than Allah — are outside the fold of Islam per orthodox Islamic theology. This is not a judgment of their character; it is a statement about what they claim to believe. Such groups should nonetheless be treated with the same basic human dignity afforded to any non-Muslim. In a modern secular state, they have the right to practice their faith. We have the right to say their claim to be Muslim is incorrect. Neither party needs to harm the other.

The Context-Dependence of Application — 14:00

How such groups are treated in practice — politically, legally, socially — is not a theoretical but a contextual question. What was appropriate in 3rd-century Baghdad is not necessarily appropriate in modern Pakistan or America. Our children today are leaving Islam altogether. In that context, the significance of relatively minor sectarian differences diminishes compared to the enormous challenge of keeping young people connected to faith at all.

Applying the harshness of Mamluk-era fatawa to 21st-century communities is simply incorrect. Scholars who are thoughtful and forward-looking will recognize this. The guidance must be calibrated to time, place, and the actual challenges the community faces.

Conclusion — 18:00

The bottom line: we must discuss correct and incorrect belief — this is a duty. We must correct incorrect theology wisely and without incitement to hatred or violence. We must respect the humanity of every person regardless of their theological category. We must not preach violence, civil war, or forced conversion.

We can say someone's belief is wrong and still smile at them, help them, and treat them as a human being deserving of dignity. That is the middle path Islam calls us to. And Allah knows best.
