Uzinzi ni uovu mkubwa ambao unaweza kuiharibu jamii. Unapingana na manufaa ya maadili ya kimataifa ya kulinda nasaba, kulinda usafi wa maadili na heshima ya watu binafsi. Unaeneza chuki na uadui miongoni mwa watu, kwa kuwa kufanya zinaa kunawaathiri wake, mama, dada na binti za watu wengine. Unaleta uharibifu kwa jamii ya binadamu, na kwa hiyo unashika nafasi ya pili baada ya uovu wa kuua, kwa kiwango cha ubaya wake. Imam Ahmad alisema: "Sijui uovu mkubwa zaidi baada ya kuua (mtu asiye na hatia) kuliko uzinzi. Allah ~ amethibitisha kuwa ni haramu, akisema: ({Wale ambao hawamwombi mungu mwingine pamoja na Allah, wala hawaui nafsi ambayo Allah ameiharamisha isipokuwa kwa haki, wala hawazini; na atakayefanya hivyo atapata adhabu. Adhabu itazidishwa kwake Siku ya Kiyama, na atadumu humo kwa kudhalilika, isipokuwa wale wanaotubu}) 7 Basi Allah ~ amelinganisha uzinzi na shirki na kuua watu (bila haki), na amefanya malipo ya tendo hilo ovu kuwa makao ya milele na adhabu mara mbili Motoni, ikiwa mtu hataacha tabia hiyo kwa toba ya kweli, akiwa na imani safi na akitenda mema. Allah ~ amesema: ({Wala msiukaribie uzinzi; hakika ni dhambi kubwa na njia mbaya}) 8 Dhambi hii kubwa inachukiwa na akili ya kawaida, na hata wanyama wengi wanaikataa, kama ilivyopokewa katika Sahih Al-Bukhari, kwa mapokezi ya Amru bin Maymun Al-Awdy, aliyesema: "Katika kipindi cha ujinga kabla ya Uislamu niliona tumbili jike amezungukwa na tumbili kadhaa. Wote walikuwa wakimpiga mawe hadi kufa pamoja na tumbili aliyefanya kitendo cha zinaa kisicho halali." Allah ~ anasema kwamba miongoni mwa njia za mtu kufanikiwa Akhera ni kuhifadhi usafi wake wa kijinsia: (Hakika wamefanikiwa waumini, wale wanaonyenyekea katika Swala zao, na wale wanaojiepusha na upuuzi, na wale wanaotoa Zakah, na wale wanaohifadhi tupu zao, isipokuwa kwa wake zao au kwa wale waliyowamiliki mikono yao ya kulia, kwani hapo hawalaumiwi; lakini anayetaka zaidi ya hayo, basi hao ndio wavukao mipaka) 1 Kama alivyosema Allah ~, Mwanadamu ameumbwa mwenye haraka; anapompata shari huwa mwenye kulalamika, na anapompata kheri huwa mchoyo, isipokuwa wale ambao Allah ~ amewatenga, tena katika Aya ifuatayo: (wale wanaohifadhi tupu zao (yaani sehemu zao za siri na vitendo haramu vya kujamiiana), isipokuwa kwa wake zao au (watumwa wa kike) waliowamiliki mikono yao ya kulia, kwani hao hawalaumiwi. Lakini anayetaka zaidi ya hayo, basi hao ndio wavukao mipaka.)2

Fornication is a great evil which can destroy society . It is contrary to the benefit of the global values of preserving lineage, protecting chastity and the sanctity of individuals. It spreads animosity and enmity among people, as committing adultery affects other people's wives, mothers, sisters and daughters. It causes destruction to human society, and therefore comes after the evil of killing in terms of the grade of its evil. Imam Ahmad said: "I don't know a greater evil after killing (an innocent person) than adultery. Allah ~ affirmed its unlawfulness, saying: ( Those who do not invoke any other god along with Allah, nor kill such person as Allah has forbidden, except for just cause, nor commit illegal sexual intercourse - and whoever does this shall receive the punishment. The torment will be doubled to him on the Day of Resurrection, and he will abide therein in disgrace, except those repent) 7 So Allah ~ has compared adultery with polytheism and killing people (without a just cause), and made the recompense for such evil act an eternal abode and double punishment in Hell , if the person does not give up such behaviour with sincere repentance, having good faith and performing good deeds . Allah ~ has said: (Do not come near adultery, verily it is a great sin and an evil way.) 8 This great sin is abhorred by common sense, and even many animals repel it, as it was reported in Sahib Al- Bukhari, on the authority of Amru bin Maymun Al-Awdy who said: "During the pre-Islamic period of ignorance I saw a she-monkey surrounded by a number of monkeys. They were all stoning it to death along with the monkey who had committed unauthorised sexual intercourse." Allah ~ states that among the ways for a person to succeed in the Hereafter is to preserve his/her chastity: ( Successful indeed are the believers, those who offer their Salat with all solemnity and full submissiveness, and those who turn away from falsehood, and those who pay Zakat, and those who guard their chastity, except from their wives or the slaves which their right hands possess - for then, they are free from blame; but whoever seeks beyond that, then those are the transgressors) 1 As Allah ~ said, Man was created very impatient; he is irritable when evil affects him, and when good affects him, he is niggardly, except those whom Allah ~ has singled out, again , in the following Verse: ( those who guard their chastity (i.e. private parts from illegal sexual acts), except from their wives or (the women slaves) whom their right hands possess - for then they are not blameworthy. But whosoever seeks beyond that, then it is those who are trespassers.)2
