Commentary
The seventh injunction given here relates to the forbiddance of zina (fornication, adultery). Given here are two reasons as to why it has been forbidden: (1) This is a shame, gross and immodest. Whoever is denuded of modesty is denuded of human nobility itself and is rendered incapable of distinguishing the good from the bad. This is more succinctly said in a Hadith:
اِذَا فَاتَک الحیاء فافعل ماشٔت
When goes your sense of shame (that could become a barrier against evil), so then, you will do what you will.
Therefore, the Holy Prophet ﷺ has declared sense of shame (haya' ) as a division of faith ('Iman): وَالحیاء شعبۃ من الایمان (al-Bukhari) (2) It generates limitless social disorder the consequences of which sometimes destroy whole groups of people. In our day all sorts of crimes have in-creased. If investigated, the reason behind a lot of them would turn out to be some man or woman who did it. Though, this crime is not directly related to the rights of the servants of Allah but it may have been mentioned here as part of other rights taken up at this place for the reason that this crime is contagious. It brings other crimes along which disturb the rights of the servants of Allah through loss of lives and properties. Therefore, Islam has declared this crime to be more serious than any other crime. Then, it has also fixed its punishment as the harshest of all crimes because this one is a carrier of hundreds of these.
It appears in Hadith that the Holy Prophet ﷺ said, "The heavens and the earth, the seven of them each, curse the married person who commits adultery. And the strong stench which spreads out from the private parts of such people will embarrass even the people condemned to Hell and thus there in Hell they will be suffering from the punishment of fire and disgrace both." (Reported by al-Bazzar on the authority of Sayyidna Buraidah - Mazhari) In another Hadith from Sayyidna Abu Hurairah ؓ it has been reported that the Holy Prophet ﷺ said, "A fornicator when fornicating is not a believer. A thief when stealing is not a believer. And a drunkard while drinking is not a believer." This Hadith is there in al-Bukhari and Muslim. Its explanation, as it appears in the report of Abu Dawud, says: At the time those committing such crimes are practically involved in it, 'Iman (faith) leaves their heart and comes out, and when they turn away from it, 'Iman returns back in.
