It is narrated from Hazrat Khawlah (may Allah be pleased with her) that once Hasan and Husain (may Allah be pleased with them both) came running to the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) embraced them and said: "Children become a cause of miserliness and cowardice, and you are the sweet basil of Allah, and that last seizure which the Most Merciful inflicted upon the disbelievers was at the place of Waj."
