يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِنَّمَا ٱلْخَمْرُ وَٱلْمَيْسِرُ وَٱلْأَنصَابُ وَٱلْأَزْلَٰمُ رِجْسٌۭ مِّنْ عَمَلِ ٱلشَّيْطَٰنِ فَٱجْتَنِبُوهُ لَعَلَّكُمْ تُفْلِحُونَ ﴿٩٠﴾
信道的人们啊! 饮酒、赌博、拜像、求签，只是一种秽行，只是恶魔的行为，故当远离，以便你们成功。
Scholars differ General principles
Is chess permitted?
Short answer
Scholars differ. Many forbid it when it is played for money (as gambling, 5:90) or if it makes a person neglect prayer. The Shafi'i school permitted it as disliked, and the other schools often forbade it. Games that cause no sin or neglect are allowed in general, so avoid betting and keep prayer on time.
