The event of Mi'raj is referenced in which Surah?

The event of Mi'raj (the Prophet Muhammad's ascension through the heavens) is referenced in Surah Al-Najm (The Star, Surah 53). Verses 53:13-18 describe the second encounter during which the Prophet saw Jibril (Gabriel) in his true form near Sidrat al-Muntaha (the Lote Tree of the Utmost Boundary), and witnessed the signs of Allah in the highest heavens.

It is important to distinguish the Mi'raj from the Isra. The Isra (the night journey from Makkah to Masjid al-Aqsa in Jerusalem) is referenced in Surah Al-Isra (17:1). The Mi'raj (the ascension from Jerusalem through the seven heavens) is described in Surah Al-Najm. Since the question specifically asks about the Mi'raj, Al-Najm is the correct answer.

The other surahs listed are unrelated to this event: Al-Ma'un (Surah 107) discusses small acts of kindness and neglect of prayer; Al-Baqarah (Surah 2) covers broad themes of guidance and law; and Al-Nur (Surah 24) deals primarily with social conduct and modesty.
