The Surah takes its name from the word al-waqi\`ah of the very first verse.
Period of Revelation
According to the chronological order that Hadrat Abdullah bin Abbas has given of the Surahs, first Surah Ta Ha was sent down, then Al-Waqi'ah and then Ash-Shu\`ara'(Suyuti: Al-Itqan). The same sequence has been reported from Ikrimah (Baihaqi: Dala'il an Nubuwwat).
Theme and Subject Matter
Its theme is the Hereafter, Tauhid and refutation of the Makkan disbelievers' suspicions about the Qur'an. What they regarded as utterly incredible was that Resurrection would ever take place, then the entire system of the earth and heavens would be upset, and when all the dead would be resurrected and called to account, after which the righteous would be admitted to Paradise and the wicked cast into Hell. They regarded all this as imaginary, which could not possibly happen in actual fact. In answer to this, it was said: "When the inevitable event will take place, there will be none to belie its happening, nor will anyone have the Power to avert it, nor prove it to, be an unreal happening.
