مَا عَلَى الرَّسُولِ إِلَّا الْبَلَاغُ ۗ وَاللَّهُ يَعْلَمُ مَا تُبْدُونَ وَمَا تَكْتُمُونَ ٩٩
The Messenger's duty is but to proclaim (the message). But Allah knoweth all that ye reveal and ye conceal.
5:100
قُلْ لَا يَسْتَوِي الْخَبِيثُ وَالطَّيِّبُ وَلَوْ أَعْجَبَكَ كَثْرَةُ الْخَبِيثِ ۚ فَاتَّقُوا اللَّهَ يَا أُولِي الْأَلْبَابِ لَعَلَّكُمْ تُفْلِحُونَ ١٠٠
Say: "Not equal are things that are bad and things that are good, even though the abundance of the bad may dazzle thee; so fear Allah, O ye that understand; that (so) ye may prosper."
5:101
يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَسْأَلُوا عَنْ أَشْيَاءَ إِنْ تُبْدَ لَكُمْ تَسُؤْكُمْ وَإِنْ تَسْأَلُوا عَنْهَا حِينَ يُنَزَّلُ الْقُرْآنُ تُبْدَ لَكُمْ عَفَا اللَّهُ عَنْهَا ۗ وَاللَّهُ غَفُورٌ حَلِيمٌ ١٠١
O ye who believe! Ask not questions about things which, if made plain to you, may cause you trouble. But if ye ask about things when the Quran is being revealed, they will be made plain to you, Allah will forgive those: for Allah is Oft-forgiving, Most Forbearing.
5:102
قَدْ سَأَلَهَا قَوْمٌ مِنْ قَبْلِكُمْ ثُمَّ أَصْبَحُوا بِهَا كَافِرِينَ ١٠٢
Some people before you did ask such questions, and on that account lost their faith.
5:103
مَا جَعَلَ اللَّهُ مِنْ بَحِيرَةٍ وَلَا سَائِبَةٍ وَلَا وَصِيلَةٍ وَلَا حَامٍ ۙ وَلَٰكِنَّ الَّذِينَ كَفَرُوا يَفْتَرُونَ عَلَى اللَّهِ الْكَذِبَ ۖ وَأَكْثَرُهُمْ لَا يَعْقِلُونَ ١٠٣
It was not Allah who instituted (superstitions like those of) a slit-ear she-camel, or a she-camel let loose for free pasture, or idol sacrifices for twin-births in animals, or stallion-camels freed from work: It is blasphemers who invent a lie against Allah; but most of them lack wisdom.
