Imam Malik ibn Anas, May Allah have mercy upon him, said:
وَقَالَ أَحْمَد بْن صَالِح الْمِصْرِيّ عَنْ اِبْن وَهْب عَنْ مَالِك قَالَ : إِنَّ الْعِلْم لَيْسَ بِكَثْرَةِ الرِّوَايَة وَإِنَّمَا الْعِلْم نُور يَجْعَلهُ اللَّه فِي الْقَلْب .
“Knowledge doesn’t consist of narrating many narrations, indeed, knowledge is but a light which Allah places in the heart.”
(Tafsir Quran al-Azim, reported on the authority of Ahmad ibn Salih al-Misri and the early Maliki, Egyptian Jurist -‘Abdullahi ibn Wahb)
