The Holy Prophet (s) has said: Whoever memorizes and preserves for my people forty Hadith pertaining to their religion, with the aim of seeking the pleasure of Allah and the Hereafter, Allah will raise him on the Day of Judgment in the company of Jurists and Religious Scholars.
These Forty Hadith are from the Holy Prophet (s) and are simple and easy to memorize. Many of them are quite familiar. Mu’mineen can also add more Hadith to extend their collection. May the Almighty make us among those who memorize forty Hadith (and more) and act upon them.
