Musnad Ahmad 1153:673

Muhammad ibn Ja'far narrated to us, he said: Shu'bah narrated to us, from Sulayman, he said: I heard Khaythamah narrating from Abu 'Atiyyah, from 'Aishah, that she said: "I indeed know how the Talbiyah of the Messenger of Allah, may Allah bless him and grant him peace, was." Then I heard her after that reciting the Talbiyah: "Labbayk Allahumma Labbayk, Labbayk la sharika laka Labbayk, inna al-hamda wa an-ni'mata laka" (Here I am, O Allah, here I am; here I am, there is no partner for You, here I am; indeed, all praise and grace belong to You).
