ahmad-zuhd:495ʿAbdullāh > Bī > Abū al-Rabīʿ > Abū al-Ashhab > Muḥammad b. Wāsiʿ

[Machine] Luqman said to his son, "Do not learn what you do not know until you act upon what you do know."  

الزهد لأحمد:٤٩٥حَدَّثَنَا عَبْدُ اللَّهِ حَدَّثَنِي أبِي حَدَّثَنَا أَبُو الرَّبِيعِ حَدَّثَنَا أَبُو الْأَشْهَبِ عَنْ مُحَمَّدِ بْنِ وَاسِعٍ قَالَ

قَالَ لُقْمَانُ لِابْنِهِ «لَا تَتَعَلَّمْ مَا لَمْ تَعْلَمْ حَتَّى تَعْمَلَ بِمَا تَعْلَمُ»
