If we were to say that there is no rejection to be shown in issues of difference in an unrestricted manner, then the religion as a whole would disappear, because you will hardly find an issue except that there is differing between the scholars regarding it.

The issue of difference divide into two types:

The first type: The issues of ijtihād in which differing is permitted. Meaning, that differing is established in reality, and it is a matter of investigation. There is no rejection to be shown upon the mujtahid in these affairs. As for the common people then they are bound to what the scholars of their land are upon [in such affairs], so that the common-folk do not slip away. Because, if were to say to the common person, “Whichever saying you come across, you can adopt it”, then the ummah would not be a single ummah. For this reason, our shaykh, ʿAbd al-Raḥmān bin Saʾdī (رحمه الله) said: “The common-folk are upon the madhhab of their scholars.”

The second type of the two types of differing: There is no permissibility in it, and there is no place for ijtihād therein. Thus, the opposer is shown rejection [in this type of differing] because there is no excuse for him [in the presence of texts and established evidences].
