Suhayla
Yes. Suhayla is formed as a feminine diminutive from Suhail and traces to the root s‑h‑l which means 'easy' or 'smooth' in Arabic; it is attested in Arabic naming traditions.
No proper name Suhayla appears in the Quran. The name is part of the broader corpus of classical Arabic personal names rather than the Quranic onomasticon.
In classical and modern Arabic pronunciation it is typically rendered as 'Su‑hay‑la' with a short u vowel on the first syllable and the diminutive pattern in the middle syllable.
Suhayla connotes gentleness, smoothness, and approachability; as a diminutive it can also signal affection or refinement in family naming customs.
Suhayla remains relatively rare compared with more popular Arabic feminine names; it is chosen by some families who favor classical yet uncommon diminutive names.
