Maisir is totally prohibited by Islamic law (Arabic: شريعة, romanized: shari'a) on the grounds that "the agreement between participants is based on immoral inducement provided by entirely wishful hopes in the participants' minds that they will gain by mere chance, with no consideration for the possibility of loss".
[2] Author Muhammad Ayub defines maisir as "wishing something valuable with ease and without paying an equivalent compensation for it or without working for it, or without undertaking any liability against it by way of a game of chance",[2] Another source, Faleel Jamaldeen, defines it as "the acquisition of wealth by chance (not by effort)".
'O believers, wine and gambling, idols and divining arrows are an abhorrence, the work of Satan.
Satan only desires to arouse discord and hatred among you with wine and gambling, and to deter you from the mention of God and from prayer.
'By Al-lāt and al-‘Uzzá,' should say, 'None has the right to be worshipped but God; and whoever says to his friend, 'Come, let me gamble with you,' should give something in charity."
