Things to do on Friday

"There is an hour, on the day of al-Jumuah, during which Allah answers the prayers and supplications. Most scholars agree that this hour is the last hour of the day, after the Salatul Asr, Ask of Allah in the last hour after the Asr." {Naas'i}

5 deeds when done on a day chosen by Allah (al-Jumuah) will be rewarded by Entry into Paradise:
1. Visiting the sick 
2. Attending the funeral 
3. Fasting a day * 
(* Should be followed or preceded by another day of fasting, means fast either Thur & Fri or Fri & Sat. But never fast just on Friday. ).
4. Going to Salatul Jumuah 
5. And the freeing of a slave. " {Sahih Ibn Hibban}

Whoever recites Surat al-Kahf on Friday, light shall shine forth for him between the two Fridays. [Ibn Hajar, Talkhis al-Habir]

From Abu Sa’eed al-Khudri, who said: “Whoever reads Soorat al-Kahf on the night of Jumu’ah, will have a light that will stretch between him and the Ancient House (the Ka’bah).” 
(Narrated by al-Daarimi, 3407. This hadeeth was classed as saheeh by Shaykh al-Albaani in Saheeh al-Jaami, 6471) 


Abu Hurairah Radiallahu anhu reports that the Holy Prophet said,

“Whoever recites the following Durood eighty times immediately after Asr Salaat on Friday, before standing up from his place, Allah will forgive eighty years of sins and grant him the reward equivalent to eighty years of worship.”

(Allahumma salli alaa muhammadinin nabiyyil ummiyyi wa-ala aalihi wasallim tasleema)

Translation: O Allah bless Muhammad, the unlettered Prophet, and his family and grant them best of peace.
