أَيُّهَا الَّذِينَ ءَامَنُواْ إِذَا نُودِىَ لِلصَّلَوةِ مِن يَوْمِ الْجُمُعَةِ فَاسْعَوْاْ إِلَى ذِكْرِ اللَّهِ وَذَرُواْ الْبَيْعَ ذَلِكُمْ خَيْرٌ لَّكُمْ إِن كُنتُمْ تَعْلَمُونَ O you who believe! When the call is proclaimed for the Salah on Al-Jumu`ah (Friday), then hasten (Fas`aw) to the remembrance of Allah and leave off business. That is better for you if you did but know! Jumu'-ah : 9
