Is the beard considered a criterion for accepting or rejecting a suitor?

Question:
The questioner says: I am a believing, monotheistic girl, praise be to Allah, and I hold the creed of the Salaf. My father is ill with diabetes and high blood pressure. Every time a committed brother proposes to me, he asks about my family, and that becomes an obstacle to the marriage. Now, a brother who is ordinary—meaning he only commits to prayer—has proposed to me. He does not grow a beard. I discussed the matter of the beard with him, and he said, "I am not convinced by it and do not want to let it grow." What should I do? I do not want to help him in this sin, whether by proposing to him or by whatever this is called. I also do not want to anger my father, as he is ill and has agreed to this, and the date for the marriage contract has been set for a few days from now. Please issue a ruling on my case, and may Allah reward you with good.

Answer:
In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah. May Allah send prayers and blessings upon the Messenger of Allah, his family, his Companions, and whoever follows the guidance. As for this, the subject of this question is that a woman has been proposed to by a man who prays, but he has a deficiency in his religion regarding not growing his beard. She advised him about it, and he mentioned that he is not convinced by it, as if he is ignorant of what has come in the Shari'ah regarding it. For this reason, he said he is not convinced. My advice to this girl is not to marry someone like him, for a person who is not convinced by what the Messenger of Allah (peace and blessings be upon him) said is dangerous. I swear by Allah, he is weak. It is not befitting for her to entangle herself with this man, for he might intend prayer and say he is not convinced by prayer, or he might intend fasting and say he is not convinced by fasting, and so on.
So the result is that a man like this is poor in religion, but fear Allah. May Allah make her affair easy. Allah says: "And whoever fears Allah, He will make for him a way out." And He forgives him of his affairs. And He counts it. And He says, Exalted is He: And in the hadith from him (peace and blessings be upon him): "Whoever leaves [something] for the sake of Allah, Allah will replace it with something better for him." The point is that if this man is ignorant of the matter, and the matter of the beard is a known matter, and authentic hadiths have been established from the Messenger of Allah (peace and blessings be upon him). He said (peace and blessings be upon him) in the hadith: "Trim the moustaches and let the beards grow, and differ from the polytheists." The point is that this man...
If he is ignorant, he should be taught, and the matter of the beard is a well-known matter. Authentic hadiths have been established from the Messenger of Allah (peace and blessings be upon him). The Prophet (peace and blessings be upon him) said in the hadith:
These sayings from the Messenger of Allah (peace and blessings be upon him) are clear and do not need explanation or interpretation. Abu Muhammad ibn Hazm, who is one of the most knowledgeable people, said regarding consensus and disagreement: "The scholars agreed that trimming the moustache and letting the beard grow is an obligatory matter." So the advice is: do not marry this man. If her father orders her to do so, she should excuse herself to her father with kind words and a good manner, and say: "O my father, this man is lax in his religion, and I fear for my religion because of him. I fear that his presence with me and my being his wife will harm me." She should convince her father with kind words and a good manner. Allah says, Glorious and Exalted is He, in His great Book: "And there is no obedience to wrongdoers in what is wrong." The Prophet (peace and blessings be upon him) said: "Obedience is only in what is right; there is no obedience to a creature in disobedience to the Creator." And this man is one from whom she fears harm. So if she refuses to marry him, there is no blame on her, even if her father is angry. Yes. This is the principle of the matter. I advise you to choose... This contains a misguidance. It is a known hadith that it is authentic, meaning he said that Allah ordered him to let the trees grow. When he said "I give it to you" and "His Lord ordered him to shave it," this is a fabricated hadith. A fabricated hadith is sufficient to know the truth, and an authentic hadith is sufficient. So an authentic hadith is sufficient.
