Musannaf Ibn Abi Shaybah 31237 — Supplication without intention

Abd al-Rahman bin Yazid said: When I came, Alqamah told me of the statement of Rabi', and I said to him: "Have you not heard the statement of Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him)?" He asked: "What is his statement?" Abd al-Rahman bin Yazid said: Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: "By the One besides whom there is no god, Allah Almighty does not hear the call of one who seeks to be heard by people, nor of a show-off, nor of one at play, nor of any caller, except the supplication of one who calls upon Him with a firm heart."
