In The Name of Allaah, The Most Merciful, The Bestower of Mercy
Allaah [The Most High] said:
يَا أَيُّهَا الَّذِينَ آمَنُوا إِذَا نُودِيَ لِلصَّلَاةِ مِنْ يَوْمِ الْجُمُعَةِ فَاسْعَوْا إِلَىٰ ذِكْرِ اللَّهِ وَذَرُوا الْبَيْعَ ۚ ذَٰلِكُمْ خَيْرٌ لَكُمْ إِنْ كُنْتُمْ تَعْلَمُونَ
فَإِذَا قُضِيَتِ الصَّلَاةُ فَانْتَشِرُوا فِي الْأَرْضِ وَابْتَغُوا مِنْ فَضْلِ اللَّهِ وَاذْكُرُوا اللَّهَ كَثِيرًا لَعَلَّكُمْ تُفْلِحُونَ
O you who believe (Muslims)! When the call is proclaimed for the Salat (prayer) on the day of Friday (Jumu’ah prayer), come to the remembrance of Allah [Jumu’ah religious talk (Khutbah) and Salat (prayer)] and leave off business (and every other thing), that is better for you if you did but know! Then when the (Jumu’ah) Salat (prayer) is finished, you may disperse through the land, and seek the Bounty of Allah (by working, etc.), and remember Allah much, that you may be successful. [Soorah Al-Jum’ah. Aayaat 9-10]
Few Reminders from the above Aayaat
Allaah [The Most High] commands His believing slaves to attend the Jumu’ah prayer and that they hasten towards it when the call for it is proclaimed. And ‘hastening’ towards it means to come to it- giving it importance and making it the most important [affair].
[وَذَرُوا الْبَيْعَ -Leave off business]-Meaning: Leave off business when the call for the prayer is proclaimed and perform it, for indeed [ذَٰلِكُمْ خَيْرٌ لَكُمْ – that is better for you] than preoccupying yourself with business and missing the obligatory prayer, which is from the most emphasised of obligations; [إِنْ كُنْتُمْ تَعْلَمُون – if you did but know!] that what Allaah has with Him [of reward] is better and more everlasting, and that the one who prefers the worldly life over the religious [commandments and prohibitions], then indeed he has [incurred] a real loss, whilst thinking that he has profited. This command to leave off business is during the time of the prayer.
[فَإِذَا قُضِيَتِ الصَّلَاةُ فَانْتَشِرُوا فِي الْأَرْضِ – Then when the (Jumu’ah) Salat (prayer) is finished, you may disperse through the land] to seek earnings and business (transactions)].
And when it is the case that preoccupation with business is most likely to make a [person] heedless of the remembrance of Allaah, Allaah commanded that He be remembered much, saying:
[وَاذْكُرُوا اللَّهَ كَثِيرًا – and remember Allah much]- Meaning: Whilst you’re standing, sitting and reclining;
[لَعَلَّكُمْ تُفْلِحُونَ – that you may be successful]; for indeed an increase in remembrance of Allaah is the greatest means to success.
