«اِلْعَدَاوَهْ فِي الْأَهْلْ»

The proverb states plainly that enmity is something found inside the family. It places hostility not at a distance but among one's own relatives, the people with whom one is most closely bound.

Used as a remark, it reminds listeners that kinship does not guarantee goodwill. It is a general observation, not a claim that every family is hostile: blood ties can coexist with bitter feeling.

Fits a comment on a quarrel, rivalry, or lingering grudge between relatives, offered as a rueful acknowledgment that friction among kin is nothing unusual, without implying that every family is hostile.
