It is reported that a man once came to Al-Shaʿbī – Allāh have mercy on him – and asked him about something, so he replied:

“Ibn Masʿūd used to say such-and-such [about this issue].” The man asked, “But tell me your opinion.” He replied, “Are you not all astonished by this man? I inform him of what Ibn Masʿūd [said] and he asks me my opinion. My religion is more important to me than that. By Allāh, I would rather sing a song than inform you of my opinion.”
