Masruq (may Allah have mercy on him) said: Umm Ruman (may Allah be pleased with her) narrated to them; she said: I was sitting with Sayyidah Aishah (may Allah be pleased with her) when a woman of the Ansar came and said: "May Allah do such and such to so-and-so and so-and-so!" Sayyidah Aishah asked: "What is the matter?" She said: "Such and such." Sayyidah Aishah asked: "Has the Messenger of Allah (peace and blessings be upon him) heard this?" She said: "Yes." She asked: "And Abu Bakr too?" She said: "Yes." The narrator said: Sayyidah Aishah fell down unconscious, and when she came to, a shivering fever had come over her, and garments were thrown over her. The Prophet (peace and blessings be upon him) came while she was lying down and asked: "What has happened to her?" The people said: "A shivering fever has come over her." He (peace and blessings be upon him) said: "Perhaps it is because of something she has been told." Sayyidah Aishah sat up and said: "By Allah, if I swear an oath, you will not believe me, and if I offer an excuse, you will not excuse me. My example and yours is like that of Ya'qub and his sons: 'And it is Allah whose help is sought against what you describe' [Surah Yusuf: 18]." The Messenger of Allah (peace and blessings be upon him) went out, and her vindication came down. She said: "With the praise of Allah, not with praise of you," or she said: "With the praise of Allah, not with praise of anyone."
