Al-Sha'bi's paternal uncle, Qays bin Abd, said: I sat in the gathering of Sayyiduna Ibn Mas'ud (may Allah be pleased with him) for a year, and I never heard him narrate any hadith from the Messenger of Allah (peace and blessings be upon him) except once, and I saw him tremble like a palm branch. Then he said: "Close to this, or like this."
