حَدَّثَنِي عَنْ مَالِكٍ أَنَّهُ بَلَغَهُ أَنَّ لُقْمَانَ الْحَكِيمَ أَوْصَى ابْنَهُ فَقَالَ: يَا بُنَيَّ جَالِسِ الْعُلَمَاءَ، وَزَاحِمْهُمْ بِرُكْبَتَيْكَ، فَإِنَّ اللَّهَ يُحْيِي الْقُلُوبَ بِنُورِ الْحِكْمَةِ، كَمَا يُحْيِي اللَّهُ الْأَرْضَ الْمَيْتَةَ بِوَابِلِ السَّمَاءِ

Ḥadīth [1950]: Mālik reported: Luqmān al-Ḥakīm enjoined upon his son, saying: “O my son, sit with the scholars and keep close to them. Allāh gives life to the hearts with the light of wisdom just as He gives life to the dead earth with rain from the sky.”
