Is the prayer of one who shaves his beard accepted?

The questioner : In a question regarding the same topic, if shaving the beard is forbidden, does that mean the worship and prayer of one who does not have a beard are not permissible or not accepted? And what is the legal text that decrees the prohibition?

The Shaykh : There is a treatise by one of the Moroccans in which he argues for the invalidity of the prayer of those who shave their beards.

The questioner: Allahu Akbar.

The Shaykh : Do not rush, O Shaykh. We have read and studied this treatise well, and we found that the man cites hadiths, some of which are authentic and some are not. Nevertheless, in this collection of hadiths, there is not a single hadith—even if it were a fabricated one—that explicitly states that the one who shaves his beard has no prayer. Rather, he arrived at this ruling, which he titled "The Invalidity of the Prayer of the One Who Shaves His Beard," through a mistaken deduction. This position is derived from the school of Ibn Hazm (may Allah have mercy on him), the Zahiri, who established a legal principle that anyone who prays and commits a forbidden act during his prayer has an invalid prayer. He has a sequential logic in which he says that if, for example, one prays while wearing a silk garment, he has not prayed as Allah (Mighty and Majestic) commanded him. Allah commanded him to pray in pure clothes, free from impurity in substance or meaning. Since he has not prayed as Allah (Mighty and Majestic) commanded him, his prayer is not valid.
