The Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), says: I said to the Prophet (peace and blessings be upon him): We too will go on military expeditions and jihad with you. The Messenger of Allah (peace and blessings be upon him) said: "But the best and most excellent jihad is an accepted Hajj (Hajj mabrur)." Sayyidah Aishah (may Allah be pleased with her) says: Since I have heard this from the Messenger of Allah (peace and blessings be upon him), I will never abandon Hajj.
