﴿ ۞ يَسْـَٔلُونَكَ عَنِ ٱلْخَمْرِ وَٱلْمَيْسِرِ ۖ قُلْ فِيهِمَآ إِثْمٌۭ كَبِيرٌۭ وَمَنَٰفِعُ لِلنَّاسِ وَإِثْمُهُمَآ أَكْبَرُ مِن نَّفْعِهِمَا ۗ وَيَسْـَٔلُونَكَ مَاذَا يُنفِقُونَ قُلِ ٱلْعَفْوَ ۗ كَذَٰلِكَ يُبَيِّنُ ٱللَّهُ لَكُمُ ٱلْءَايَٰتِ لَعَلَّكُمْ تَتَفَكَّرُونَ ﴾

“THEY WILL ASK thee about intoxicants and games of chance. Say: "In both there is great evil as well as some benefit for man; but the evil which they cause is greater than the benefit which they bring." And they will ask thee as to what they should spend [in God's cause]. Say: "Whatever you can spare." In this way God makes clear unto you His messages, so that you might reflect”
