According to the Sunnah, when is the correct time to recite Surat Al-Kahf on Friday? And is reciting Surat Aal 'Imran on Friday from the Sunnah, and if so, when should it be recited?

There are authentic hadiths regarding the virtue of reciting Surat Al-Kahf on Friday or its eve. Among them is that it illuminates a light for its reciter extending between him and the Ancient House (the Kaaba), or between the two Fridays, or a light shines for him that illuminates for him on the Day of Resurrection, and he is forgiven for what is between the two Fridays. The time for its recitation extends from sunset on Thursday until sunset on Friday. As for reciting Surat Aal-Imran on Friday, there are no authentic hadiths regarding it; what has been reported is very weak or fabricated.
