The ruling on the prayer of one who shaves his beard, or usurps land or a garment and prays in it

The Shaykh : This logic invalidates dozens of forms of prayer simply because the one praying has opposed the wise Lawgiver in one of the commands of the Shari'ah, or has committed one of the prohibitions of the Shari'ah. The majority of scholars disagree with this understanding, except in one issue where they agree with him... The prayer is valid. As for Ibn Hazm, and before him Imam Ahmad, they invalidate the prayer of one who prays in usurped land. This is a precise jurisprudential issue, and I see no harm in mentioning it, knowing that many of our brothers, like us, from among the students of knowledge are present in this place. There is a rule: if the wise Lawgiver prohibits something that is not related to the prayer itself—meaning that thing is prohibited not because it is in the prayer, but because it is absolutely prohibited, such as the usurpation we are discussing, whether of land or of a garment—this is all forbidden and prohibited. If a person praying commits a prohibition of this type, the prayer is valid, but he is sinful because he has disobeyed his Lord (Mighty and Majestic) in this usurpation, because this usurpation is not permissible whether he is sitting in prayer or sitting to eat and drink, or otherwise. However, if a prohibition comes regarding something specifically in the prayer, and that thing, if separated from the prayer, has no sin in it, then the prayer is invalid due to the occurrence of that thing which is prohibited specifically in the prayer. For example, it is prohibited to be brief in the prayer. It is prohibited to be brief in the prayer. What does being brief mean? That a person sometimes gets tired and does this... Well, if he does this action outside of prayer, there is no sin in it. So this prohibition is specific to the prayer. And it is prohibited to pray being brief in the prayer, as in some hadiths. So this prohibition, since it is specific to the prayer, indicates that the prayer is invalid. Based on this rule, one can answer the original question: a man shaves his beard here and stands up to pray from here. This shaving is not prohibited specifically for the prayer, but it is general, like the prohibition of wearing silk. If a person prays in silk, or wears a gold ring, if he prays wearing a gold ring, the prayer is valid, but he is sinful because he has opposed the prohibitions, which include wearing silk and wearing gold, specifically for men. So, if a person is afflicted with shaving the beard, he must stop it immediately, not because the prayer is invalid, but because he is thereby disobeying his Lord (Blessed and Exalted is He). Yes.
