وَهُمْ يَنْهَوْنَ عَنْهُ وَيَنْأَوْنَ عَنْهُ
They forbid others from it, and they themselves keep away from it.
In mudariʿ, the words differ in a consonant whose place of articulation is close to that of its counterpart. “Yanhawna” means “they forbid,” while “yanʾawna” means “they keep away.”
The contrast between hāʾ and hamzah preserves audible affinity without collapsing two independent acts into the same meaning.
