Alqamah said: Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) used to stand up (and address the people) every Thursday evening, and I never heard him on any of those evenings, except once, say: "The Messenger of Allah (peace and blessings be upon him) said." The narrator said: I looked at him, and he was leaning on a staff, and I saw that the staff was shaking.
