One day Khadijah was seated in her house while her bonds-women and slaves encircled her. One of the Jewish scholars was also present. By chance the Prophet passed that way and the Jewish scholar saw him. He at once requested Khadijah to insist upon Muhammad that he should postpone his task and join that party for a few moments. The Prophet accepted the request of the Jewish sage, which was based on observation of the signs of prophethood in his person.
Khadijah then turned to the Jewish sage and said "When his uncles will become aware of your investigation and inquisitiveness they will display an adverse reaction, because they are afraid of the Jews about their nephew". The Jewish sage then replied: "How can it be possible that anyone should harm Muhammad, when the hand of destiny has reared him up for the last prophethood and for the guidance of the people?" Khadijah said: "On what authority do you say that he will come to hold this position?"
He replied: "I have read the signs of the last Prophet in the Taurat. His signs include three things that is his parents will die, his grandfather and uncle will support him, and he will choose for his spouse a woman, who will be the lady of Quraysh". Then he pointed to Khadijah and said: "Blessed is she who has the honour of being his life-mate".
