Ḥātim al-Farāhijī related: “I heard Faḍālah al-Nasawī say, ‘I heard Ibn al-Mubārak say:
“It is binding on any intelligent person not to treat lightly three classes of people: the scholars, the rulers, and one’s brethren. Whoever belittles the scholars forfeits his afterlife; whoever belittles the ruler forfeits his worldly life; and whoever belittles his brethren forfeits his muruʾah (honor and moral integrity).”’
Al-Qushayrī said: I heard al-Sulamī say, “I traveled to Marw while the Master Abū Sahl al-Ṣuʿlūkī was still alive. Before I left, he used to hold on Friday mornings a dawr (1) for complete Qurʾān recitation. When I returned I found that he had discontinued that session and had instead convened, for Ibn al-ʿUqābī (2), a gathering devoted to al-qawl—that is, singing. This unsettled me, and I kept saying to myself, ‘He has exchanged the khatm gathering for a qawl gathering.’
“One day he said to me, ‘Abū ʿAbd al-Raḥmān, what are people saying about me?’
“I replied, ‘They are saying that you abolished the Qurʾān session and instituted a session of qawl.’
“He responded, ‘Whoever says to his shaykh, “Why?” will never prosper.’ (3)
“I add: The disciple should not say to his shaykh, ‘Why?’ if he believes him to be maʿṣūm (protected from error), for in that case error is impossible for him. But if the shaykh is not infallible yet dislikes to be asked, ‘Why?’, then he will never succeed. Allah the Exalted says: ‘And cooperate in righteousness and piety.’ (Al-Māʾidah 2)”
