Abu Atiyyah al-Wadi'i says: I heard Sayyidah Aishah (may Allah be pleased with her) saying: By Allah, I know how the talbiyah of the Messenger of Allah (peace and blessings be upon him) was. Then I heard her reciting the talbiyah: "Labbayk Allahumma labbayk, labbayk la sharika laka labbayk, inna al-hamda wa al-ni'mata lak" (Here I am, O Allah, here I am; here I am, You have no partner, here I am. Indeed, all praise and blessing are Yours).
