Al-Husayn ibn Muhammad al-Ash‘ari from Mu‘alla ibn Muhammad from Muhammad ibn Jumhur from ’Abd al-Rahman ibn abu Najran from one he mentioned from abu ‘Abdallah who has said the following.
مَنْ حَفِظَ مِنْ أَحَادِيثِنَا أَرْبَعِينَ حَدِيثاً بَعَثَهُ الله يَوْمَ الْقِيَامَةِ عَالِماً فَقِيهاً.
“Whoever would preserve and memorize forty of our Hadith on the Day of Judgment Allah will raise him as a scholar and Faqih, one with proper understanding of religion.”
Al-Kāfi, v.1, Book 2, Chapter 16
