Al Jumu’ah Ayah 9

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓاْ إِذَا نُودِىَ لِلصَّلَوٲةِ مِن يَوْمِ ٱلْجُمُعَةِ فَٱسْعَوْاْ إِلَىٰ ذِكْرِ ٱللَّهِ وَذَرُواْ ٱلْبَيْعَ‌ۚ ذَٲلِكُمْ خَيْرٌ لَّكُمْ إِن كُنتُمْ تَعْلَمُونَ ٩ O believers! When the call to prayer is made on Friday, then proceed ?diligently? to the remembrance of Allah and leave off ?your? business. That is best for you, if only you knew.
