It is recommended to do a lot of recitation of the Qurʾān, adhkār and supplications on the day of Friday and the night, as well as prayers upon the Messenger of Allah, may Allah’s prayers and peace be upon him, and the recitation of Sūrat al-Kahf in the day. Al-Shāfiʿī, may Allah have mercy on him, said in the book al-Umm, ‘It is recommended to read it on Friday night.’

Imam al-Nawawi
