(This part of an ongoing translation of Sheikh Shithrī’s treatise pertaining laws and principles for the non-Mujtahid).
If a layman asks a group of scholars a question and their answers differ from one another, it becomes incumbent upon his to give preference to one of the opinions based upon the righteousness and scrupulousness of the scholar. This is because there is no other distinguishing way to choose between the variant opinions and also because it is more likely that the more righteous and scrupulous scholar is, the more likely he will be correct. Therefore it is not permissible for him to go against what he thinks is most likely to be correct.
Also, one of the two opinions is bound to be incorrect since the truth will always lie in only one of the opinions. Therefore, when there is a conflict of views the layman must adopt an opinion that is more likely to be correct in accordance to the righteousness and scrupulousness of the scholar just as the mujtahid must choose the strongest of two evidences.
The layman is required to follow the law of Allāh (swt) and it is not possible for him to know what the law of Allāh (swt) is unless he knows the statement of the scholars. Therefore, if he comes across a variety of different opinions, he must act in accordance to what he thinks is the law of Allāh (swt), whether that be due to the great number of scholars that adopt a particular opinion or due to the virtue and righteousness of them or due to the evidence that is available to him.
