Kainat
Kainat is used in South Asia and derives from Persian/Urdu usage of Arabic-root vocabulary; it is not a classical Arabic proper name but is built from Arabic lexical material and is common in Sindhi/Urdu contexts.
In Urdu Kainat (کائنات) means 'the universe' or 'all created existence'.
No classical Quranic verse lists Kainat as a proper personal name; however, concepts of creation and the universe appear in many Quranic passages.
Kainat is recognized and used in Pakistan and parts of India among Urdu and Sindhi speakers, though it remains less common internationally.
Kainat is primarily a feminine given name; there is no widely attested masculine equivalent used as a personal name.
