Sinniyah

Could you specify what Sinniyah refers to? There are multiple places and uses of that name across the Arabic-speaking world (towns, districts, islands, coastal features, etc.). If you provide the country or region, I can draft a concise, neutral wiki-style article tailored to that Sinniyah. Alternatively, I can produce a disambiguation-style stub that lists the known uses and outlines the ambiguities.
