In the Quran
Sakīnah (Arabic: سكينة) signifies the "presence or peace of God". As "support and reassurance" it was "sent by God into the hearts" of Muslims and Muhammad, according to John Esposito. A modern translator of the Quran, N. J. Dawood, states that "tranquility" is the English word for the Arabic meaning of sakīnah, yet it could be "an echo of the Hebrew shekeenah (the Holy Presence)." Another scholar states that the Arabic Sakīnah derives from the Hebrew/Aramaic shekhinah. In the Quran, the Sakīnah is mentioned six times, in surat al-Baqara, at-Tawba and al-Fath.
Their prophet said to them: "The sign of his kingship is that the Ark will come to you in which there is tranquility from your Lord and a relic from the family of Moses and the family of Aaron, borne by the angels. In this is a sign for you if you are true believers. [Quran 2:248 (Translated by Tarif Khalidi)]
Sakīnah means "tranquility", "peace". "calm", from the Arabic root sakana: "to be quiet", "to abate", "to dwell". In Islam, Sakīnah "designates a special peace, the "Peace of God". Although related to Hebrew shekhinah, the spiritual state is not an "indwelling of the Divine Presence"[need quotation to verify] The ordinary Arabic use of the word's root is "the sense of abiding or dwelling in a place". A story in Tafsir and Isra'iliyyat literature relates how Ibrahim and Isma'il, when looking for the spot to build the Kaaba found sakīnah. Newby writes that it was like a breeze "with a face that could talk", saying "build over me." "Associated with piety and moments of divine inspiration, sakinah in Islamic mysticism signifies an interior spiritual illumination."
