Allah groups intoxicants (khamr) and gambling (maysir) together as 'an abomination from the handiwork of Satan' and commands believers to avoid them entirely (Qur'an 5:90). He identifies their social danger explicitly: Satan uses them to 'sow enmity and hatred among you' and to bar people from the remembrance of Allah and from prayer (Qur'an 5:91). While an earlier verse acknowledged they carry 'some benefit for people,' it rules that 'their sin is greater than their benefit' (Qur'an 2:219), which is why the scholars treat the prohibition as absolute.
