يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓاْ إِذَا نُودِيَ لِلصَّلَوٰةِ مِن يَوۡمِ ٱلۡجُمُعَةِ فَٱسۡعَوۡاْ إِلَىٰ ذِكۡرِ ٱللَّهِ وَذَرُواْ ٱلۡبَيۡعَۚ ذَٰلِكُمۡ خَيۡرٞ لَّكُمۡ إِن كُنتُمۡ تَعۡلَمُونَ ٩
O you who have believed, when [the adhān] is called for the prayer on the day of Jumuʿah [Friday], then proceed to the remembrance of Allāh and leave trade. That is better for you, if you only knew.
Translation: Saheeh International (English)
Each word's meaning and sound
O you who have faith in Allah, and who act on what He has ordained for you, when the caller to prayer calls out on the day of Friday after the speaker ascends the pulpit, then hurry to the mosques to attend the speech and the prayer and leave trading, so that it does not distract you from obedience. That hurrying and leaving out trading after the call for the Friday prayer is better for you, O believers. If you know that, then fulfil what Allah has instructed you to do.
