It is not permissible to disparage or criticize the imams of the schools of jurisprudence and their fiqh; and whatever has been issued by some of those who claim affiliation with the Salafi call in contradiction to this, its issuer is in error.

The Shaykh : The second point: We must acknowledge it, and that is that some individuals among those affiliated with the Salafi call sometimes utter words that are sometimes explicit in criticizing the schools of jurisprudence, and sometimes suggestive. We say: This is not permissible in our religion and our belief; because the mujtahid scholars, as we always and forever affirm, are rewarded whether they are correct or they err; by the evidence of his saying (peace and blessings be upon him): ; therefore, what we believe is that he is rewarded by Allah (Mighty and Majestic) in all cases, no matter what we know of these imams regarding their asceticism, their fear of their Lord, their turning away from this world, and their standing firm in the truth that they believed in; all of this does not allow us in any way...
...that the youth of Muslims, who do not fit the description of seeking knowledge or conducting research, are not burdened with the same responsibility as those distinguished ones. In the previous lesson, he described the Salafi call, stating that they call for following the Book and the Sunnah, and that they study the four schools of jurisprudence and discuss their evidence, and he described this call as a call to truth. But now he wants to clarify that this work, which requires scientific research, is not something the general public can do. This is a correct statement, but what he built upon it is incorrect, as you will hear.
