The shortest surah in the Quran is Suratul Kawthar. This surah has only three verses and is the 108th chapter of the Quran. The word "Kawthar" means abundance or plenty, and the surah speaks about the great blessings that Allah has bestowed upon the Prophet Muhammad (peace be upon him).
In this surah, Allah consoles the Prophet after he had lost his infant son and was mocked by his enemies for having no male heir. Allah reminds him that he has been given abundant goodness and blessings that will continue to flow for generations to come. The surah also warns those who oppose the Prophet that they will be cut off from goodness and blessings.
Although it is a short surah, it carries a powerful message about the blessings and bounty of Allah and the importance of remaining steadfast in the face of adversity.
