Al-Ma'idah 5:93

<h2>Prohibiting Khamr (Intoxicants) and Maysir (Gambling)</h2><p>Allah forbids His believing servants from consuming Khamr and Maysir which is gambling. Ibn Abi Hatim recorded that `Ali bin Abi Talib, the Leader of the Faithful, said that chess is a type of gambling. Ibn Abi Hatim recorded that `Ata', Mujahid and Tawus, or , two of them, said that every type of gambling, including children's playing with (a certain type of) nuts, is Maysir. Ibn `Umar said that Al-Maysir means gambling, and this is the same statement that Ad-Dahhak reported from Ibn `Abbas, who added, "They used to gamble during the time of Jahiliyyah, until Islam came. Allah then forbade them from this evil behavior."</p><h2>Meaning of Ansab and Azlam</h2><p>Al-Ansab were altar stones, in whose vicinity sacrifices were offered (during the time of Jahiliyyah), according to Ibn `Abbas, Mujahid, `Ata', Sa`id bin Jubayr and Al-Hasan. They also said that Al-Azlam were arrows that they used for lotteries to make decisions, as Ibn Abi Hatim narrated. Allah said,</p><p>رِجْسٌ مِّنْ عَمَلِ الشَّيْطَـنِ</p><p>(A Rijs of Shaytan's handiwork) meaning, abomination of Shaytan's handiwork, according to `Ali bin Abi Talhah who reported it from Ibn `Abbas. Sa`id bin Jubayr said that Rijs means `sin' while Zayd bin Aslam said; …

There shall be no sin (imputed) unto those who believe and do good works for what they may have eaten (in the past). So be mindful of your duty (to Allah), and believe, and do good works; and again: be mindful of your duty, and believe; and once again: be mindful of your duty, and do right. Allah loveth the good.

On those who believe and do deeds of righteousness there is no blame for what they ate (in the past), when they guard themselves from evil, and believe, and do deeds of righteousness,- (or) again, guard themselves from evil and believe,- (or) again, guard themselves from evil and do good. For Allah loveth those who do good.

Those who believe and do righteous good deeds, there is no sin on them for what they ate (in the past), if they fear Allah (by keeping away from His forbidden things), and believe and do righteous good deeds, and again fear Allah and believe, and once again fear Allah and do good deeds with Ihsan (perfection). And Allah loves the good-doers.

Those who believe and do righteous deeds will not be blamed for what they may have eaten, provided they obey, and believe, and do good deeds, then maintain piety and faith, then remain righteous and charitable. God loves the charitable.
