How to check a claim about Islam

Checking is part of the religion

Checking a claim isn't disloyal. The Quran tells believers to do it:

O you who have believed, if there comes to you a disobedient one with information, investigate, lest you harm a people out of ignorance and become, over what you have done, regretful.

(Quran 49:6)

And the Prophet, peace be upon him, said that it is falsehood enough for a person to pass on everything they hear (Sunan Abi Dawud 4992, graded sahih by al-Albani). That goes for claims against Islam and claims for it.

The five checks

1. Pin down the claim. Write it in one sentence. "A verse says X" is a different claim from "one scholar said X" or "Muslims do X".
2. Find the source. For the Quran, the surah and verse number. Read it on Quran.com in two or three translations. For a hadith, the collection and the number, such as Sahih al-Bukhari 3276. No source means it isn't evidence yet.
3. Read the context. The verses before and after, the whole hadith rather than one line, and the situation it was about.
4. Check the grade. Hadith are graded: sahih (sound), hasan (good), da'if (weak), or fabricated. Sunnah.com shows a grade under many hadith. Scholars sometimes grade the same hadith differently. For example, the hadith with the line "The cure for ignorance is inquiry" is graded hasan by al-Albani and weak by Shu'aib al-Arna'ut (Sunan Abi Dawud 336). That's normal, and it's why the grade is worth checking.
5. See how scholars understood it. Classical commentaries such as Ibn Kathir's are on Quran.com, next to each verse. Ask: is this the mainstream reading, or a rare view presented as "what Islam says"?

A word about AI answers

AI tools can produce a hadith that sounds real, with a collection and number, that doesn't exist, or mix up the wording of one that does. Treat anything an AI tells you about Islam as a lead, not a source. Look up the collection and number yourself. If you can't find it, don't believe it, and don't pass it on. The same goes for quote images shared online.

Being honest about the hard ones

Some claims are simple misquotes. Others point to real, difficult texts that scholars have discussed for centuries. "This one is hard, and here is how scholars have read it" is an honest answer, and the doubts library will take those one at a time. The same checks apply to arguments made for Islam. Where a popular one is weaker than people say, we'll tell you.

Is this a question or a loop? If the same worry keeps coming back however many answers you read, it may be waswasa, and more answers won't settle it. Read about waswasa first.

If this is hitting you hard

A claim can feel enormous at 2am and much smaller the next morning. You're allowed to wait until you've checked it before deciding what it means. If you can't find an answer, that doesn't mean there isn't one. Write the claim down and take it to someone who knows.
