وَعَنْ أَبِي الدَّرْدَاءِ قَالَ:" إِنَّ مِنْ أَشَرِّ النَّاسِ عِنْدَ اللَّهِ مَنْزِلَةً يَوْمَ الْقِيَامَةِ: عَالِمٌ لَا ينْتَفع بِعِلْمِهِ ". رَوَاهُ الدَّارمِيّ
Translation

Abu Darda’ said that the one who would have the worst position inGod’s sight on the day of resurrection would be a learned man who didnot profit from his learning.” Darimi transmitted it.
