Whoever recites Soorah Al Kahf on the day of Jummah, will have a light that will shine from him from one Friday to the next:
Declared Authentic by Shaykh al Al-Bani
The Prophet S.A.W said: whoever recites Surah al Kahf as it was revealed, he will have a light on the day of judgement, from his place to Mecca. And whoever recites ten verses from the end of it then when the dajjal appears, he will not harm him. And whoever performs wudoo and says: Subahanaka Allahuma wa bi hamdika, ash-hadu and la ilaha illa anta. Astagfiruka wa atubu ilaika (O ALLAH, You are free from every imperfection; praise be to you. I testify that there is no deity worthy of worship except you; I seek your forgiveness and turn to you in repentance)
I will be written for him in parchment, and it will be placed in a seal, and it will not be broken until the day of judgement.
