Al-Qadr (Arabic: القدر‎, "Power, Fate") is the 97th chapter (surah) of the Qur'an with 5 verses (ayat). This sorat is positioned in Para 30 which is also known as Juz Amma (Juz' 30). It is a Meccan / Makki surah which celebrates the night when the first revelation of what would become the Qur'an was sent down. The surat has been so designated after the word al-qadr in the first verse. It is mainly about power.

Summary:
This surah describes Laylat al-Qadr, the "Night of the abundant portion of blessings" in Ramadan on which Muslims believe the Qur'an was first revealed. The "Spirit" mentioned in verse 4 is commonly interpreted as referring to the angel Jibreel (Gabriel). The "peace" referred to is called by Mujahid "security in which Shaytan (Iblis) cannot do any evil or any harm", while Ibn Kathir quotes Ash-Sha'bi as saying that it refers to the angels greeting the people in the mosques throughout the night.

Layla tul Qadr occurs during an odd-numbered night within the last ten days of Ramadan / Ramzan, but its exact date is uncertain; due to the promises made in the surat and in various hadith. Muslims consider it a particularly good time for prayer, supplication, and repentance to God. This event marks the descent of the first revelation of the Quran to Earth. The official Islamic teaching is that Muhammad received the revelations that formed the al-Quran piecemeal for the next twenty-three years of his life up until the time of his death.
