وَإِذَا رَأَوْا۟ تِجَٰرَةً أَوْ لَهْوًا ٱنفَضُّوٓا۟ إِلَيْهَا وَتَرَكُوكَ قَآئِمًۭا ۚ قُلْ مَا عِندَ ٱللَّهِ خَيْرٌۭ مِّنَ ٱللَّهْوِ وَمِنَ ٱلتِّجَٰرَةِ ۚ وَٱللَّهُ خَيْرُ ٱلرَّٰزِقِينَ
But when they spy some merchandise or pastime they break away to it and leave thee standing. Say: That which Allah hath is better than pastime and than merchandise, and Allah is the Best of providers.
