It is narrated from Sayyiduna Imran bin Husayn (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "I do not fear anything for Quraysh except their own selves." I said: "What is that?" He (peace and blessings be upon him) said: "Extremely miserly and greedy. If you are granted a long life, you will see them miserly and greedy with people's wealth, until you see the people among them like sheep between two watering troughs, sometimes going to this one and sometimes to that one."
