Is the aforementioned Hadith regarding the virtue of reciting Surat Az-Zumar authentic?

We have not come across this Hadith in the books of Sunnah, but it is authentically established that the Prophet, peace and blessings be upon him, used to regularly recite Surat Az-Zumar every night, as narrated by Aisha, may Allah be pleased with her: "And he used to recite every night Bani Israel (Surat Al-Isra) and Az-Zumar."
