(Al-Baqara) 2 : 219
يَسْأَلُونَكَ عَنِ الْخَمْرِ وَالْمَيْسِرِ ۖ قُلْ فِيهِمَا إِثْمٌ كَبِيرٌ وَمَنَافِعُ لِلنَّاسِ وَإِثْمُهُمَا أَكْبَرُ مِنْ نَفْعِهِمَا ۗ وَيَسْأَلُونَكَ مَاذَا يُنْفِقُونَ قُلِ الْعَفْوَ ۗ كَذَٰلِكَ يُبَيِّنُ اللَّهُ لَكُمُ الْآيَاتِ لَعَلَّكُمْ تَتَفَكَّرُونَ
They ask you about liquor and gambling. You say: “In both of them there are serious sins as well as the benefit for mankind, and their sin is greater than their benefit”; and they are asking you what they should spend, You say: “What is beyond your needs”. Just like that Lord Allah is explaining His verses upon you, so that you may meditate and reflect.
