”O you who believe (Muslims)! When the call is proclaimed for the Salat (prayer) on the day of Friday (Jumu’ah prayer), come to the remembrance of Allah [Jumu’ah religious talk (Khutbah) and Salat (prayer)] and leave off business (and every other thing), that is better for you if you did but know!
Then when the (Jumu’ah) Salat (prayer) is finished, you may disperse through the land, and seek the Bounty of Allah (by working, etc.), and remember Allah much, that you may be successful.”
(9/10, Surah Jumu’ah)
