Sahih al-Bukhari 3659

Al-Humaydi and Muhammad ibn ‘Abd Allah reported to us; they both said: Ibrahim ibn Sa‘d reported to us, from his father, from Muhammad ibn Jubayr ibn Mut‘im, from his father, who said: A woman came to the Prophet (peace and blessings be upon him), and he told her to return to him. She said, ‘What do you think—if I came and did not find you?’ It was as though she meant: death. He said to her, ‘If you do not find me, then go to Abu Bakr.’
