Meaning and root
From z-y-d (ز-ي-د). *Al-ziyāda* is increase and growth, the opposite of *nuqṣān*; *Zayd* is the verbal noun used as a name, and the same root gives Ziyād, Zaydān and Mazyad.
The grammarians' name
Zayd is the name every reader of Arabic knows without its ever being a particular man. The grammarians made it their stock example — *ḍaraba Zaydun ʿAmran*, 'Zayd struck ʿAmr' — so that across the literature of grammar Zayd and ʿAmr stand in for anyone at all.
What the verse settled about nasab
It is also the only Companion's name mentioned outright in the Qur'an, in sūrat al-Aḥzāb — and the story of that name is genealogy's own. The reports have it that he was called Zayd ibn Muḥammad by adoption; when the verse *udʿūhum li-ābāʾihim*, 'call them by their fathers', came down he was returned to his own father and was Zayd ibn Ḥāritha thereafter. A person's *nasab* runs to the father he was born to, not to the one who raised him. Care and lineage are both real; a record keeps them in separate columns.
Frequently asked questions
Why do Arabic grammar books always say 'Zayd'?
Zayd and ʿAmr are the grammarians' stock placeholders — the equivalent of naming no one in particular. The convention is old enough that it now passes unremarked.
Is a person's nasab reckoned to the father who raised him?
No. It is reckoned to the father he was born to — the point settled when Zayd ibn Muḥammad became Zayd ibn Ḥāritha again. A record should show fostering and lineage separately.
