Why were paternal uncles, maternal uncles, foster brothers, and husbands of daughters mentioned among those before whom a woman may display her adornment in the verse of lowering the gaze in Surat An-Nur?

The noble verse mentions the maharim (unmarriageable kin) with whom a woman frequently interacts in her daily life, such as sons and brothers, while remaining silent about the paternal uncle (amm) and maternal uncle (khal). This is not because their ruling differs from the aforementioned maharim, but rather because the enumeration was based on what is most common. To these maharim by lineage are appended maharim by suckling, due to the Prophet’s (peace be upon him) saying: "What is forbidden by lineage is also forbidden by suckling."
