«وَلَدْ لِخَالُهْ»

The saying observes that a boy's temperament and habits often mirror those of his mother's brother. It treats this likeness as something expected, almost a rule of family life, so that a nephew's character can be explained by pointing to his maternal uncle.

It speaks of resemblance in nature, not of the boy belonging to or being raised by his uncle. Because it frames resemblance as inherited, the remark can be affectionate or critical depending on the uncle's reputation.

Say it when a boy shows habits, moods, or a disposition strikingly like his mother's brother, whether admirable or troublesome. It works as a passing remark among relatives or acquaintances who know both people, explaining a trait by family likeness.
