The Noble Shaykh Saalih al-Fawzaan (may Allaah preserve him) stated:

The Muslim is in need of three matters when there is differing, in order for him to know the correct path:

Firstly: The correct knowledge and not the pretend knowledge. It is not possible for you to traverse upon this path except that you have learned and you know the truth from the misguidance.

Secondly: Having  patience and being firmly established. Not wavering even if you are afflicted by that which befalls you. Indeed you are to remain patient no matter how much it costs you (to do so).

Thirdly: Do not be deceived by the large amount (of people who are upon something). Indeed you only look at who is upon the truth.
