The Book Pertaining to the Merits of the Companions (Allah Be Pleased With Them) of the Holy Prophet (May Peace Be Upon Him) (Kitab Al-Fada'il Al-Sahabah)
Muslim :: Book 31 : Hadith 5878
Muhammad b. Jubair b. Mut'im reported on the authority of his father that a woman asked Allah's Messenger (may peace be upon him) about something but lit, told her to come to him on some other occasion, whereupon she said: What in your opinion (should I do) if I come to you but do not find you, and it seemed as if she meant that he might die. Thereupon he said: If you do not find me, then come to Abu Bakr.
This hadith has been narrated on the authority of Jubair b. Mut'im through another chain of transmitters (and the words are) that a woman came to Allah's Messenger (may peace be upon him) and discussed with him something and he gave a command as we find in the above-mentioned narration.
