Sukaina (سكينة) is the diminutive of the Arabic sakīna (tranquility, divine presence). **Sayyida Sukaina bint al-Husayn (c. 671-735)** was the daughter of Imam Husayn and great-granddaughter of Prophet Muhammad — a poet and patron of literature in early Islamic Medina.
Highly venerated in Shia Islam.
Sukaina reduces to five — the number of Arabic tranquility.
