Surah An-Noor, Verse 26:
الْخَبِيثَاتُ لِلْخَبِيثِينَ وَالْخَبِيثُونَ لِلْخَبِيثَاتِ وَالطَّيِّبَاتُ لِلطَّيِّبِينَ وَالطَّيِّبُونَ لِلطَّيِّبَاتِ أُولَٰئِكَ مُبَرَّءُونَ مِمَّا يَقُولُونَ لَهُم مَّغْفِرَةٌ وَرِزْقٌ كَرِيمٌ
Bad statements are for bad people (or bad women for bad men) and bad people for bad statements (or bad men for bad women). Good statements are for good people (or good women for good men) and good people for good statements (or good men for good women), such (good people) are innocent of (each and every) bad statement which they say, for them is Forgiveness, and Rizqun Karim (generous provision i.e. Paradise).
So take this as filteration of bad elements and Allah states about such
Surah An-Noor, Verse 3:
الزَّانِي لَا يَنكِحُ إِلَّا زَانِيَةً أَوْ مُشْرِكَةً *وَالزَّانِيَةُ لَا يَنكِحُهَا إِلَّا زَانٍ أَوْ مُشْرِكٌ وَحُرِّمَ ذَٰلِكَ عَلَى الْمُؤْمِنِينَ*
The adulterer marries not but an adulteress or a Mushrikah *and the adulteress none marries her except an adulterer or a Muskrik* [and that means that the man who agrees to marry (have a sexual relation with) a Mushrikah (female polytheist, pagan or idolatress) or a prostitute, then surely he is either an adulterer, or a Mushrik (polytheist, pagan or idolater, etc.) *And the woman who agrees to marry (have a sexual relation with) a Mushrik (polytheist, pagan or idolater) or an adulterer, then she is either a prostitute or a Mushrikah* (female polytheist, pagan, or idolatress, etc.)]. *Such a thing is forbidden to the believers* (of Islamic Monotheism).
So we must thank Allah for filtering such bad elements and leaving good ones for us...
