Musnad Ahmad 1153:1179

'Abd al-Razzaq narrated to us, Ma'mar narrated to us, from Jabir, from 'Arfajah, from 'Aishah, who said: The Prophet, may Allah bless him and grant him peace, entered upon me one day and said: "I have done something today that I wish I had not done. I entered the House (the Ka'bah), and I fear that a man may come from some horizon of the horizons, and he will not be able to enter it, so he will return with something in his soul regarding it."
