It is narrated from Sayyiduna Ibn Amr, may Allah be pleased with him, that a man came to the Prophet Muhammad, peace and blessings be upon him, seeking permission to participate in jihad. The Prophet, peace and blessings be upon him, asked: "Are your parents alive?" He replied, "Yes." The Prophet, peace and blessings be upon him, said: "Then go and strive in service to them."
