All significant treatises, both divine and non-divine, have been founded, no matter their subject matters were and what they seemingly profess, on the sole fact that in man, the negative nature has reigned supreme, since the time of his inception. Simultaneously, these books, both ancient and recent, have reserved substantial portions for devising ways and means to cure the evil side of man. Each of these books, from the dawn of human civilization till the present day of miraculous technology, including the Holy Qurān and the works of as great literary giants as those of William Shakespeare, testifies to this unalterable fact. Both Sharī’ah (Islamic Law) and the works, chiefly, the four tragedies of William Shakespeare show that, besides many other vices, human nature is primarily blighted by the moral and psychological diseases of lust, gluttony and greed. However, at the same time, they discuss and offer cures to these moral illnesses in the form of chastity, temperance and love. All these cures may be rightly called Islamic legal ethics. The present study, one of its kind, attempts first to point out the vices, and second, to pinpoint their cures in the shape of Islamic legal ethics. The methodology adopted in this paper is qualitative in nature that exploits the content analysis technique for the exhaustive examination of the secondary data, painstakingly collected from both the works.
