Al-Ḥayy or Ḥayy () is one of the greatest names of God in Islam, meaning The Ever Living.Sa’di, A. A. al-R. N. (2008). In Explanation to the Beautiful and Perfect Names of Allah (pp. 39–40). Daar Us-Sunnah. Al-Hayy is all-seeing, all-hearing, and all-powerful, without experiencing drowsiness or fatigue. This name also alludes to the idea that all creatures—angels, humans, jinn, and animals—receive life from God in the Islamic worldview. Additionally, God imparts life to the hearts of humans through his speech (the Quran).
The Prophet once asked Ubayy ibn Ka'b to identify the greatest verse in the Quran. The companion answered by saying Ayat Al-Kursi, and the prophet praised him for recognizing it.
Ayat Al-Kursi (the Verse of the Throne)
Al-Hayy is considered one of the greatest names of God, as it is mentioned in the Throne Verse (Ayat Al-Kursi) of Surah al-Baqarah, considered by many Muslims the greatest verse of the Quran, with Muslim children and youth memorizing this verse:Seyyed Hossein Nasr, ed. (2018). The Study Quran. HarperCollins Publishers. p. 110.
(اللَّهُ لَا إِلَهَ إِلَّا هُوَ الْحَيُّ الْقَيُّومُ لَا تَأْخُذُهُ سِنَةٌ وَلَا نَوْمٌ لَهُ مَا فِي السَّمَاوَاتِ وَمَا فِي الْأَرْضِ مَنْ ذَا الَّذِي يَشْفَعُ عِنْدَهُ إِلَّا بِإِذْنِهِ يَعْلَمُ مَا بَيْنَ أَيْدِيهِمْ وَمَا خَلْفَهُمْ وَلَا يُحِيطُونَ بِشَيْءٍ مِنْ عِلْمِهِ إِلَّا بِمَا شَاءَ وَسِعَ كُرْسِيُّهُ السَّمَاوَاتِ وَالْأَرْضَ وَلاَ يَؤُودُهُ حِفْظُهُمَا وَهُوَ الْعَلِيُّ الْعَظِيمُ)
