Ibn ‘Abdul Barr reported: Imam Malik ibn Anas, may Allah have mercy on him, said, “Surely, it is the duty of a student of knowledge to behave with dignity, calm, and reverence, and to follow the narrations of those who came before him.”

عن ابن عبد البر قال مالك بن أنس رحمه الله إِنَّ حَقًّا عَلَى مَنْ طَلَبَ الْعِلْمَ أَنْ يَكُونَ لَهُ وَقَارٌ وَسَكِينَةٌ وَخَشْيَةٌ وَأَنْ يَكُونَ مُتَّبِعًا لآثَارِ مَنْ مَضَى قَبْلَهُ
