Surah Introduction Surah 56: al-Waqi`ah (The Occurrence)
The Surah talks about the resurrection that will definitely take place. It is a fact undeniable. The human beings then will be in three different groups. The faithful are of two types: those who are the pioneers and are foremost in their faith and struggle in the path of Allah. They are a large number from amongst the earlier community and a small from among the later generations. Then the rest of the people are believers and those who oppose the faith. Allah's rewards are for the faithful and his anger and chastisement is waiting for the opponents of faith.
The Surah then invites human beings to think about themselves and the things that they use daily and consider who created all these things. It talks about the Qur’an and its profound and consistent message and then finally reminds about death and the coming end of every being.
