الجمعة — Al-Jumu'ah Ayat 9
يٰٓاَيُّهَا الَّذِيْنَ اٰمَنُوْٓا اِذَا نُوْدِيَ لِلصَّلٰوةِ مِنْ يَّوْمِ الْجُمُعَةِ فَاسْعَوْا اِلٰى ذِكْرِ اللّٰهِ وَذَرُوا الْبَيْعَۗ ذٰلِكُمْ خَيْرٌ لَّكُمْ اِنْ كُنْتُمْ تَعْلَمُوْنَ
Yā ayyuhal-lażīna āmanū iżā nūdiya liṣ-ṣalāti miy yaumil-jumu‘ati fas‘au ilā żikrillāhi wa żarul-bai‘(a), żālikum khairul lakum in kuntum ta‘lamūn(a).
"O you who have believed, when [the adhan] is called for the prayer on the day of Jumu'ah [Friday], then proceed to the remembrance of Allah and leave trade. That is better for you, if you only knew."
