It is narrated from Sayyiduna Mu'awiyah bin Jahimah (may Allah be pleased with him) that Jahimah came to the Prophet (peace and blessings be upon him) and said: I intend to go out for jihad and I have come to consult you. He (peace and blessings be upon him) said: "Is your mother alive?" He said: Yes. He (peace and blessings be upon him) said: "Go and stay in her service, for Paradise is beneath her feet." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
