Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) said: A man came to the Prophet (peace and blessings be upon him) and said: I intend to wage jihad. The Prophet (peace and blessings be upon him) asked: "Are your parents alive?" He said: Yes. He (peace and blessings be upon him) said: "Go back to them; in (serving) them both lies the place of jihad."
