What are the children of the Prophet's paternal uncles and maternal aunts, and are they educated or merchants?

The biographers did not mention any of the children of the Prophet’s maternal uncles and the sisters of his mother, Aminah bint Wahb, except for his maternal uncle 'Abd Yaghuth ibn Wahb, and his maternal aunt Al-Furay'ah bint Wahb Az-Zuhriyah.

Other than that, they were considered his maternal uncles by virtue of their kinship to his mother, for the Arabs refer to anyone whose kinship is through the mother as a maternal uncle (khal). This is what is meant by the Almighty’s saying: (and the daughters of your maternal uncle and the daughters of your maternal aunts). What is meant by the daughters of his maternal uncle and maternal aunts are the daughters of Banu Zuhrah, both males and females.

Such detailed matters should not preoccupy a person much, unless they arise incidentally or one is specialized in historical studies. Rather, it is more fitting to occupy oneself with what is more important, such as gaining a deep understanding of the religion and knowing its laws, and the meanings of the Book and the Sunnah.
