يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِذَا نُودِىَ لِلصَّلَوٰةِ مِن يَوْمِ ٱلْجُمُعَةِ فَٱسْعَوْا۟ إِلَىٰ ذِكْرِ ٱللَّهِ وَذَرُوا۟ ٱلْبَيْعَ ۚ ذَٰلِكُمْ خَيْرٌ لَّكُمْ إِن كُنتُمْ تَعْلَمُونَ ٩
O you who have believed, when [the adhān] is called for the prayer on the day of Jumuʿah [Friday], then proceed to the remembrance of Allāh and leave trade. That is better for you, if you only knew.

9. O you who believe (Muslims)! When the call is proclaimed for the Salât (prayer) on Friday (Jumu‘ah prayer), come to the remembrance of Allâh [Jumu‘ah religious talk (Khutbah) and Salât (prayer)] and leave off business (and every other thing). That is better for you if you did but know!
