Qaf (Arabic: ق, the letter qāf), is the 50th chapter (sūrah) of the Qur'an with 45 verses (āyāt). The name is taken from the single discrete Quranic "mysterious letter" qāf that opens the chapter. It is the beginning of the Hizb al-Mufassal, the seventh and the last portion (manzil). Concepts which "Qaf" deals with the Resurrection and the Day of Judgement.
