Yusra (يسرى) is the Arabic word for "ease" or "prosperity" — appearing in the Quran (Surah Al-Layl 92:7) with the promise that God "will ease his way to ease."
**Yusra Mardini (born 1998)** is the Syrian-German Olympic swimmer who, fleeing Syria, swam her sinking boat to safety carrying refugees on the way to Lesbos.
Yusra reduces to three — the number of Quranic ease.
