Surah al-A`raf (The Elevated Places) 7 : 81

Explanatory Note

The excess to which Lot is referring is that they go beyond the limits of the divine order of things which is reflected in upright human nature. They indeed go to excess with regard to the energy God has given them in order to play their role in the survival and progress of human life, by expending it wastefully in a place other than that of fertilization. It thus becomes no more than a perverted lust. God has made both man and woman derive proper and natural pleasure in the fulfilment of natural law. When a person finds his pleasure in something contrary to this natural law, then that is a mark of the perversion and corruption of nature, let alone its being a corruption of moral values. Indeed, there is no difference between the two, because Islamic morality is an embodiment of natural moral values, free of corruption and perversion.
 
Just like her psychology, woman’s physical constitution is the one that allows the male to have his proper and natural pleasure when the two share contact which is not meant merely to satisfy a desire. Indeed, the pleasure that attends such a contact is an aspect of God’s grace and blessing. It is He who has made this activity the source of pleasure, equal to its attendant responsibility. At the same time it fulfils His will that ensures the continuity of life. The male’s physical constitution cannot provide uncorrupted human nature with pleasure if this desire is to be fulfilled with another male. Indeed, a feeling of disgust is immediately generated which blocks such a leaning as long as human nature is normal and upright.
