Sayyiduna Anas (may Allah be pleased with him) said: A man came to the Prophet (peace and blessings be upon him) and said: "I long to take part in jihad, but I am not able to." The Prophet (peace and blessings be upon him) asked: "Is either of your parents still living?" He replied: "My mother." The Prophet (peace and blessings be upon him) said: "Then please Allah Almighty by treating her well! When you do that, you will have a reward like that of one who performs Hajj, one who performs Umrah and one who fights in jihad. When your mother is pleased with you (you will receive this reward), so keep fearing Allah Almighty and treat her well."
Abu Ya'la recorded it, and al-Tabarani in al-Mu'jam al-Saghir and al-Mu'jam al-Awsat. The narrators of both are the narrators of the Sahih, except Maymun bin Najih, and Ibn Hibban declared him trustworthy.
