Zaynab is Arabic word and came from Arabic words "zayn" and "ab". ZAYN means beauty and AB means father. So zaynab means beauty of father as per Arabic dictionary. And most famous personality is the daughter of ALI (a.s.) son of ABU TALIB (a.s.)
Husayn Haykal's Zaynab is the first modern Egyptian novel published in 1913. The book depicts life in the Egyptian countryside and delves into the relationships between men and women.
Honestly, when I first read this name, it just sounded like a word spelled backwards, like "carrot" rewritten as "Torrac". Funnily enough, I actually prefer this name spelled backwards: Banyaz! The Indonesian word for "much" or "many" is "banyak" and "banyaz" feels to me like it means, "abundance". Zaynab sounds like a sci-fi character. "Tune in next week when Zaynab, Queen of the Teknits, gets lost in the Black Hole of Quaos!" -- or something like that. It's too clipped and the ending seems abrupt, and could end-up sounding like, zay-nap, or "say nap". What about, Zaynaba? It's softer. Zayna is prettier too.
