Ibn Mas’ud on Knowledge: Learn from the Prophet’s companions, elders

Sa’id ibn Wahb reported: Abdullah ibn Mas’ud, may Allah be pleased with him, said, “People will continue to be virtuous as long as they take knowledge from the companions of Muhammad, peace and blessings be upon him, and their elders. If they take their knowledge from the young, that is when they will be ruined.”

عَنْ سَعِيدِ بْنِ وَهْبٍ عَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ قَالَ رضي الله عنه لا يَزَالُ النَّاسُ بِخَيْرٍ مَا أَتَاهُمُ الْعِلْمُ مِنْ قِبَلِ أَصْحَابِ مُحَمَّدٍ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَأَكَابِرِهِمْ فَإِذَا أَتَاهُمُ الْعِلْمُ مِنْ قِبَلِ أَصَاغِرِهِمْ فَذَلِكَ حِينَ هَلَكُوا
