Abd al-Rahman bin Sabit said: The Prophet (peace and blessings be upon him) intended to part from Sawdah (may Allah be pleased with her), so he called Abu Bakr and Umar (may Allah be pleased with them both) to make them witnesses to her divorce. She said: O Messenger of Allah! I have no desire in this world except that I be counted among your wives on the Day of Resurrection, so that I may have the same reward as they have.
