It is narrated from Sayyiduna Ali (may Allah be pleased with him) that he said: "When the Messenger of Allah (peace and blessings be upon him) intended (to march on) Makkah, he (peace and blessings be upon him) sent word to some of his Companions (and informed them) that he (peace and blessings be upon him) was heading for Makkah. Among them was Hatib bin Abi Balta'ah (may Allah be pleased with him). Meanwhile, it had spread among the general public that he (peace and blessings be upon him) intended to go to Hunayn. Hatib (may Allah be pleased with him) wrote a letter to the people of Makkah saying that the Messenger of Allah (peace and blessings be upon him) intended to march on them. At this, the Messenger of Allah (peace and blessings be upon him) sent me and Abu Marthad (may Allah be pleased with him) (in pursuit of it)." Then the narrator mentioned the whole story of the letter being recovered from that woman at Rawdat Khakh, and in this narration it is also related that Habib bin Abi Thabit said: That woman took the letter out from the front of her body (the place of her private parts) and handed it over.
Abu Ya'la recorded this hadith in his Musnad. The narration is originally also found in Sahih al-Bukhari and Sahih Muslim, while the detail about where the woman hid the letter is also mentioned in other routes.
