حَدَّثَنَا أَبُو نُعَيْمٍ ، حَدَّثَنَا الْمَسْعُودِيُّ ، عَنْ الْقَاسِمِ ، قَالَ : قَالَ عَبْدُ اللَّهِ :" تَعَلَّمُوا الْقُرْآنَ وَالْفَرَائِضَ، فَإِنَّهُ يُوشِكُ أَنْ يَفْتَقِرَ الرَّجُلُ إِلَى عِلْمٍ كَانَ يَعْلَمُهُ، أَوْ يَبْقَى فِي قَوْمٍ لَا يَعْلَمُونَ

Abu Nu`aym told us, Al-Masoudi told us, on the authority of Al-Qasim, he said: Abdullah said: “Learn the Qur’an and the religious duties, for it is about to become lacking.” A man will return to the knowledge he knew, or he will remain among a people who do not know.
