O you who believe when the call for prayer is made on Friday hasten set off to the remembrance of God to the prayer and leave aside all commerce suspend all such contracts. That is better for you should you know that it is better for you then do it.
- 62:99
يَا أَيُّهَا الَّذِينَ آمَنُوا إِذَا نُودِيَ لِلصَّلَاةِ مِنْ يَوْمِ الْجُمُعَةِ فَاسْعَوْا إِلَىٰ ذِكْرِ اللَّهِ وَذَرُوا الْبَيْعَ ۚ ذَٰلِكُمْ خَيْرٌ لَكُمْ إِنْ كُنْتُمْ تَعْلَمُونَ
O believers, when proclamation is made for prayer on the Day of Congregation, hasten to God's remembrance and leave trafficking aside; that is better for you, did you but know.
