Musnad Ahmad 1267:0

Narrated to us by Waki’, from Sufyan, from Mansur, from Ibrahim, from ‘Aishah, the daughter of ‘Ajrad, from Habibah bint Abi Tajrah, who said: I saw the Messenger of Allah (ﷺ) while he was performing Tawaf around the House (the Ka'bah), and he was saying: "O Allah, forgive me and have mercy upon me, and accept my repentance, and guide me, and grant me health, and provide for me." And she said: He was walking slowly.
