Referring to the expert will relieve him from liability if the edicts of the mujtahid do not conform to the actual legislated laws of Allah Almighty. Without following the expert mujtahid, the person will be held responsible before The Almighty if the actions and transactions were not really in accordance to the religion.</p>

If you could not, you must choose the most pious amongst them and if the said is not possible too, you can choose one of them and emulate him.
