Abu Darda on Knowledge: Be a scholar, student, devotee, or follower

Al-Hasan reported: Abu Darda, may Allah be pleased with him, said, “Be a scholar, a student, a devotee, or a follower; do not be the fifth type lest you be ruined.” It was said to Al-Hasan, “Who is the fifth type?” Al-Hasan said, “A heretic.”

عَنِ الْحَسَنِ أَنَّ أَبَا الدَّرْدَاءِ رضي الله عنه قَالَ كُنْ عَالِمًا أَوْ مُتَعَلِّمًا أَوْ مُحِبًّا أَوْ مُتَّبَعًا وَلا تَكُنِ الْخَامِسَ فَتَهْلِكَ قيل لِلْحَسَنِ مَنِ الْخَامِسُ قَالَ الْمُبْتَدِعُ
