An-Najm (Arabic: النجم, an-najm; meaning: The Star) is the 53rd chapter (surah) of the Quran, with 62 verses (āyāt). The surah opens with the oath of the Divine One swearing by every one of the stars, as they descend and disappear beneath the horizon, that Muhammad is indeed God's awaited Messenger. It takes its name from Ayat #1, which mentions "the stars" (najm). The surah confirms the divine source of the Prophet's message and refers to his ascension to heaven during the Night Journey (Ayah#1 ff.). The surah refutes the claims of the disbelievers about the goddesses and the angels (ayah#19 ff.), and lists several truths about God's power. It closes with a warning of the imminent Day of Judgement.
Regarding the timing and contextual background of the believed revelation (asbāb al-nuzūl), it is an earlier "Meccan surah", which means it is believed to have been revealed in Mecca, rather than later in Medina.
