Ibn Shihab states: Sayyidah Khadijah bint Khuwaylid (may Allah be pleased with her) was the wife of the Prophet (peace and blessings be upon him) before the Qur'an was revealed to him. Then the Qur'an was revealed to him and she remained his wife. She is the first person who affirmed the truth of the Prophet (peace and blessings be upon him) and believed in him. She passed away in Makkah three years before the Prophet (peace and blessings be upon him) departed for Madinah.
Al-Tabarani recorded it; its chain also contains Ibn Zubalah, who is da'if (weak).
