Who is a mufti, and who may give a fatwa?

A mufti is a scholar trained and recognized as qualified to answer questions of Islamic law. Speaking well about religion is a different skill. Before you take an answer, ask what the speaker studied, with whom, and who recognizes them.

Why this matters in my religion

The reason is not snobbery about credentials. An answer about Islamic law is an answer about what Allah has ruled. The Qur'an treats speaking about Allah without knowledge as a serious matter in its own right:

﴿قُلْ إِنَّمَا حَرَّمَ رَبِّىَ ٱلْفَوَٰحِشَ مَا ظَهَرَ مِنْهَا وَمَا بَطَنَ وَٱلْإِثْمَ وَٱلْبَغْىَ بِغَيْرِ ٱلْحَقِّ وَأَن تُشْرِكُوا۟ بِٱللَّهِ مَا لَمْ يُنَزِّلْ بِهِۦ سُلْطَـٰنًا وَأَن تَقُولُوا۟ عَلَى ٱللَّهِ مَا لَا تَعْلَمُونَ﴾
“Say: My Lord forbiddeth only indecencies, such of them as are apparent and such as are within, and sin and wrongful oppression, and that ye associate with Allah that for which no warrant hath been revealed, and that ye tell concerning Allah that which ye know not.” — Qur'an 7:33

Read where that clause sits. It is listed alongside the gravest categories, not as a minor slip of manners.

There is a second reason, and it is about you. Qur'an 16:43 directs the person who does not know to the people of knowledge. That instruction assumes you can tell them apart from everybody else who is talking. Learning to tell them apart is therefore part of following the instruction.

The idea, simply

You will meet several kinds of religious speaker. Each role is real and useful. The only question here is whether that role, by itself, qualifies someone to answer your specific legal question.

The role	What it usually means	What it does not, by itself, establish
Preacher or da'i	Invites, reminds, and encourages	Training in deriving rulings
Media or motivational speaker	Communicates well and reaches many people	Any formal study of Islamic law
Student of knowledge	Studying under teachers; can often transmit an answer accurately	Authority to answer new or complex cases
Academic researcher	Studies Islam as a field, often historically	Training in fiqh method, or a mandate to rule
Well-known sheikh	A recognized name and a following	Training in the particular field your question falls in
Mosque imam	Leads prayer and often teaches	That he is a mufti
Mufti	Recognized by qualified peers or an institution as able to issue fatwas	That he cannot be mistaken, or that others will agree

Classical works on the ethics of issuing fatwa describe the mufti's equipment in a familiar cluster:

The Qur'an and its meanings.
The Sunnah, and the state of its narrations.
Arabic, at the level the texts are written in.
The areas where scholars agree and where they differ.
Legal method — how a ruling is derived, and by what rules.
An accurate grasp of the real situation being asked about.

The exact list and its ordering vary between works. The shape of it does not.

Notice the last item. A scholar who knows the texts perfectly and misunderstands how a financing contract actually works has not yet answered the question. This is why serious scholars ask you so many questions, and why they sometimes send you to a different scholar.

Signs worth trusting

They ask you questions back before answering.
They name where the answer comes from.
They mark the difference between "this is the ruling" and "this is my advice".
They say "I do not know" or "ask someone else" without embarrassment.
They mention that scholars differ, where they do.
They stay inside the area they were trained in.
They can be checked: known teachers, a known institution, a written authorization, a body that recognizes them.

Signs worth pausing over

An instant, confident answer to a case they know nothing about.
No source, and irritation when you ask for one.
Contempt for other scholars as a substitute for evidence.
An answer that seems to move depending on who is asking.
Certainty on a matter where the person is not trained.

None of these tells you a person is wrong. They tell you that you do not yet have grounds to rely on them, which is a different and more honest conclusion.

From life

Two talks in the same week. The first speaker fills the hall. He is moving, funny, and quotes beautifully from memory. In the corridor afterwards, a man asks how his late father's house should be divided. He gets an answer in about eight seconds.

The second speaker is quieter and half the room leaves early. The same man asks him the same question. The answer is: "That depends on who survived your father, and whether anything was owed on the house. Write it down, and bring the death certificate to the office tomorrow."

The second answer sounds like less. It is worth more. The first speaker gave a verdict on a case he had not seen. The second one recognized a case, and started the work of actually seeing it.

What does this require of me?

Ask, plainly and politely, where they studied. A qualified person is not offended by that question. Being asked is part of the job.
Match the person to the question. Many scholars specialize. Family law, finance and medical questions are not interchangeable specialties, and a strong scholar in one may decline the other.
Judge how someone answers, not how well they speak. Fluency, warmth and passion are real gifts. They are not evidence of training.
Treat "I do not know" as a credential. It usually means the person understands what a complete answer would require.
Do not appoint yourself the judge between scholars. Choosing which scholar to ask is your job. Deciding which scholar is right on a technical point is not. If two scholars disagree, whom do I follow? covers what a non-specialist can reasonably do.
When you repeat an answer, repeat its source too. Say who said it and what they were asked. Otherwise you have quietly become the mufti.

When do I need to ask a scholar?

Ask a qualified scholar, not a general article or a search result. Do this whenever the answer turns on your own facts. That includes anything about a contract, an estate, a marriage, a divorce, or your own spoken words.

Ask a specialist when the subject is technical. Modern finance, medicine and technology cases usually need someone who has studied both the ruling and the mechanism.

Ask someone familiar with your country when local law or custom is part of the picture. The same arrangement can be built differently in different places.

And be careful about where an answer originates. A confident paragraph from a search engine, a short video or a chat assistant has no teacher and no training. It also carries no responsibility for you. That question has its own article in this library.
