DARIMI 268:
from Abū al-Dardāʾ —
[Machine] I heard Abu Darda say, "Indeed, from the worst of people in the sight of Allah on the Day of Resurrection is a scholar who does not benefit from his knowledge."
الدارمي ٢٦٨:
عن ابو الدرداء —
سَمِعْتُ أَبَا الدَّرْدَاءِ يَقُولُ «إِنَّ مِنْ أَشَرِّ النَّاسِ عِنْدَ اللَّهِ مَنْزِلَةً يَوْمَ الْقِيَامَةِ عَالِمٌ لَا يَنْتَفِعُ بِعِلْمِهِ»
