Maysar (Gambling)

Maysar: the Jahiliyya's gambling by casting arrows over the shares of a slaughtered camel; the Qur'an forbade it with wine, counting it a great sin.

Among their games was gambling with the azlam over the slaughtered camel in dividing its shares: they cast the arrows — whoever drew a share took it, and whoever drew none paid the camel's price ¹.

The Prophet was asked about wine and maysar, and God sent down: "Say: in them is great sin and benefits for people; their sin is greater than their benefit" (al-Baqara 219), then explicitly forbade them in Surat al-Ma'ida among Satan's works ¹.
