Choosing a Wife

Question: If a man wants to marry a girl who is a relative of his, or from a family far removed from his own, but her brothers are not in a good state regarding intelligence and acumen, and he fears for his children’s future because of this,
is it permissible for him to turn away from her and choose someone else for this reason alone?And what is the degree of authenticity of the hadith:

Answer: Yes, a man should choose a suitable wife who is free from harmful defects for her and her children, and he should choose from good, established families; because this affects the offspring, by the permission of Allah.

As for the degree of authenticity of the hadith: This has not been established from the Prophet (peace and blessings be upon him) as a hadith, but its meaning is correct, because a man should seek out a suitable wife;As he (peace and blessings be upon him) said: he should choose one who is righteous in her religion, and also righteous in her lineage and free from physical defects, because this has an impact on the marital relationship and on the offspring, by the permission of Allah.
