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.
5:104
وَإِذَا قِيلَ لَهُمْ تَعَالَوْا إِلَىٰ مَا أَنْزَلَ اللَّهُ وَإِلَى الرَّسُولِ قَالُوا حَسْبُنَا مَا وَجَدْنَا عَلَيْهِ آبَاءَنَا ۚ أَوَلَوْ كَانَ آبَاؤُهُمْ لَا يَعْلَمُونَ شَيْئًا وَلَا يَهْتَدُونَ ١٠٤
When it is said to them: "Come to what Allah hath revealed; come to the Messenger": They say: "Enough for us are the ways we found our fathers following." what! even though their fathers were void of knowledge and guidance?
5:105
يَا أَيُّهَا الَّذِينَ آمَنُوا عَلَيْكُمْ أَنْفُسَكُمْ ۖ لَا يَضُرُّكُمْ مَنْ ضَلَّ إِذَا اهْتَدَيْتُمْ ۚ إِلَى اللَّهِ مَرْجِعُكُمْ جَمِيعًا فَيُنَبِّئُكُمْ بِمَا كُنْتُمْ تَعْمَلُونَ ١٠٥
O ye who believe! Guard your own souls: If ye follow (right) guidance, no hurt can come to you from those who stray. the goal of you all is to Allah: it is He that will show you the truth of all that ye do.
5:106
يَا أَيُّهَا الَّذِينَ آمَنُوا شَهَادَةُ بَيْنِكُمْ إِذَا حَضَرَ أَحَدَكُمُ الْمَوْتُ حِينَ الْوَصِيَّةِ اثْنَانِ ذَوَا عَدْلٍ مِنْكُمْ أَوْ آخَرَانِ مِنْ غَيْرِكُمْ إِنْ أَنْتُمْ ضَرَبْتُمْ فِي الْأَرْضِ فَأَصَابَتْكُمْ مُصِيبَةُ الْمَوْتِ ۚ تَحْبِسُونَهُمَا مِنْ بَعْدِ الصَّلَاةِ فَيُقْسِمَانِ بِاللَّهِ إِنِ ارْتَبْتُمْ لَا نَشْتَرِي بِهِ ثَمَنًا وَلَوْ كَانَ ذَا قُرْبَىٰ ۙ وَلَا نَكْتُمُ شَهَادَةَ اللَّهِ إِنَّا إِذًا لَمِنَ الْآثِمِينَ ١٠٦
O ye who believe! When death approaches any of you, (take) witnesses among yourselves when making bequests,- two just men of your own (brotherhood) or others from outside if ye are journeying through the earth, and the chance of death befalls you (thus). If ye doubt (their truth), detain them both after prayer, and let them both swear by Allah: "We wish not in this for any worldly gain, even though the (beneficiary) be our near relation: we shall hide not the evidence before Allah: if we do, then behold! the sin be upon us!"
