What is the authenticity of the Rafidah's statement that the Mother of the Believers, Aisha -may Allah be pleased with her- incited the killing of Uthman -may Allah be pleased with him-, and that she said: "Kill Na'thal, for he has disbelieved"?

Scholars have refuted what was mentioned about Aisha inciting the killing of Uthman, due to the weakness of its chains of transmission. Sheikh Al-Islam clarified that what is authentically narrated from her refutes this, and that she denounced his killing and condemned those who killed him. Al-Alusi stated that what the Shiites claimed about Aisha is a lie with no basis, and it is among the fabrications of Ibn Qutaybah, Ibn A'tham Al-Kufi, and Al-Samsati. He added that Nasr ibn Muzahim Al-Attar and Umar ibn Sa'd, who are among the narrators in the chains of these accounts, are considered discredited, abandoned, and accused of fabricating narrations.
