Evitai a fornicação, porque é uma obscenidade e um péssimo exemplo!

Quran
ٱلزَّانِيَةُ وَٱلزَّانِى فَٱجْلِدُوا۟ كُلَّ وَٰحِدٍۢ مِّنْهُمَا مِا۟ئَةَ جَلْدَةٍۢ ۖ وَلَا تَأْخُذْكُم بِهِمَا رَأْفَةٌۭ فِى دِينِ ٱللَّهِ إِن كُنتُمْ تُؤْمِنُونَ بِٱللَّهِ وَٱلْيَوْمِ ٱلْءَاخِرِ ۖ وَلْيَشْهَدْ عَذَابَهُمَا طَآئِفَةٌۭ مِّنَ ٱلْمُؤْمِنِينَ ﴿٢﴾
Quanto à adúltera e ao adúltero, vergastai-os com cem vergastadas, cada um; que a vossa compaixão não vos demova decumprir a lei de Deus, se realmente credes em Deus e no Dia do Juízo Final. Que uma parte dos fiéis testemunhe o castigo.
Hadith
Sahih al-Bukhari 2475
Narrated Abu Huraira:The Prophet (ﷺ) said, "When an adulterer commits illegal sexual intercourse, then he is not a believer at the time, he is doing it, and when a drinker of an alcoholic liquor drinks it, then he is not a believer at the time of drinking it, and when a thief steals, then he is not a believer at the time of stealing, and when a robber robs, and the people look at him, then he is not a believer at the time of doing robbery
Arabic text (with chain of narrators)
حَدَّثَنَا سَعِيدُ بْنُ عُفَيْرٍ، قَالَ حَدَّثَنِي اللَّيْثُ، حَدَّثَنَا عُقَيْلٌ، عَنِ ابْنِ شِهَابٍ، عَنْ أَبِي بَكْرِ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ النَّبِيُّ صلى الله عليه وسلم " لاَ يَزْنِي الزَّانِي حِينَ يَزْنِي وَهْوَ مُؤْمِنٌ، وَلاَ يَشْرَبُ الْخَمْرَ حِينَ يَشْرَبُ وَهْوَ مُؤْمِنٌ، وَلاَ يَسْرِقُ حِينَ يَسْرِقُ وَهْوَ مُؤْمِنٌ، وَلاَ يَنْتَهِبُ نُهْبَةً يَرْفَعُ النَّاسُ إِلَيْهِ فِيهَا أَبْصَارَهُمْ حِينَ يَنْتَهِبُهَا وَهْوَ مُؤْمِنٌ ". وَعَنْ سَعِيدٍ وَأَبِي سَلَمَةَ عَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيِّ صلى الله عليه وسلم مِثْلَهُ إِلاَّ النُّهْبَةَ.
