يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا إِذَا نُودِىَ لِلصَّلَوٰةِ مِن يَوْمِ ٱلْجُمُعَةِ فَٱسْعَوْا إِلَىٰ ذِكْرِ ٱللَّهِ وَذَرُوا ٱلْبَيْعَ ۚ ذَٰلِكُمْ خَيْرٌ لَّكُمْ إِن كُنتُمْ تَعْلَمُونَ

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.
