Two scholars say different things. Which one do I follow?
First check whether it is a real disagreement between schools or just two people giving opinions. If it is real, follow one of them consistently rather than taking from each whichever suits you. And do not mistake confidence for knowledge: the one who says “I don't know” is usually more reliable than the one who never does.
The four schools concur on this.
Running into this is disorienting at first, particularly if you arrived expecting a single book of answers.
The first thing is to tell apart two very different situations:
A real disagreement between schools. The four schools agree on the overwhelming majority of matters and differ on details, because the texts sometimes admit more than one defensible reading and each school applies a coherent method. This is not a defect: it is what intellectual honesty looks like when a text is applied to cases it did not name.
Two people giving opinions. Very different, and today far more common. Someone with an audience is not thereby someone with training.
The instruction to return disputes to the sources: “O you who have believed, obey Allah and obey the Messenger and those in authority among you. And if you disagree over anything, refer it to Allah and the Messenger, if you should believe in Allah and the Last Day. That is the best way and best in result.” (Qur’an 4:59)
And to ask those who know: “And We sent not before you, O Muḥammad, except men to whom We revealed the message, so ask the people of the message i.e., former scriptures if you do not know.” (Qur’an 21:7)
What to do in practice:
- Check the credentials: who they studied with, for how long, and whether they tell you where what they assert comes from.
- Be wary of speed. Instant answers to complicated questions are a bad sign.
- Value the “I don't know.” It is the most reliable indicator there is. The early scholars are remembered for saying it.
- Follow one consistently. Taking the most convenient ruling from each school on each matter produces a position no scholar ever held.
- Ask whether it is a disputed matter. Someone who tells you where scholars differ, instead of presenting one opinion as *the* Islamic position, is being straight with you.
And the most useful thing long term: find one or two people with real training whom you can genuinely ask, rather than settling every doubt with a search engine.
