Surah 17, al-Israʾ, opens on this journey: “Glory be to Him who took His servant by night from the Sacred Mosque to al-Aqsa Mosque, whose surroundings We have blessed, to show him some of Our signs” (17:1). The noun israʾ itself is not in the Quran: only the verb asra appears.
Israʾ is the verbal noun of asra, “to make travel by night” (root s-r-y of night travel, sura). The word refers to the Prophet’s ﷺ night journey from the Sacred Mosque in Mecca to al-Aqsa Mosque, followed by the ascension (miʿraj). The name is very common: Israa or Isra in the Arab world, Esra in Turkey, where it is among the most given.
Exalted is He who took His Servant [i.e., Prophet Muḥammad (ﷺ)] by night from al-Masjid al-Ḥarām to al-Masjid al-Aqṣā, whose surroundings We have blessed, to show him of Our signs. Indeed, He is the Hearing, the Seeing.
They [the angels] said, "O Lot, indeed we are messengers of your Lord; [therefore], they will never reach you. So set out with your family during a portion of the night and let not any among you look back - except your wife; indeed, she will be struck by that which strikes them. Indeed, their appointment is [for] the morning. Is not the morning near?"
So set out with your family during a portion of the night and follow behind them and let not anyone among you look back and continue on to where you are commanded."
