Al-Musayyab bin Najabah al-Fazari said: We were sitting with Sayyiduna Ali (may Allah be pleased with him) when the people mentioned his household, so Sayyiduna Ali (may Allah be pleased with him) said: "As for Hasan, he would be of no use to you in war, not even as much as a sparrow's snare; as for Abdullah bin Ja'far, he is a man of ease and the dining spread; and as for Husayn, he is from you and you are from him."
