Musannaf Ibn Abi Shaybah 32405 — Book of Faith

Abu Uthman said that Sayyiduna Salman (may Allah be pleased with him) said: It will be said to him, meaning the Prophet (peace and blessings be upon him): "Ask, and you will be given. Intercede, and your intercession will be accepted. Supplicate, and it will be answered." Then he (peace and blessings be upon him) will raise his head and say, two or three times: "My Ummah, my Ummah!" Then Sayyiduna Salman (may Allah be pleased with him) said: He (peace and blessings be upon him) will intercede for everyone who has in his heart faith equal to a grain of wheat, or he said: faith equal to a grain of barley, or he said: faith equal to a mustard seed. Sayyiduna Salman (may Allah be pleased with him) said: This, for you, is the Praised Station (al-Maqam al-Mahmud).
