أَفَلَا يَتَدَبَّرُونَ الْقُرْآنَ ۚ وَلَوْ كَانَ مِنْ عِندِ غَيْرِ اللَّهِ لَوَجَدُوا فِيهِ اخْتِلَافًا كَثِيرًا
Then do they not reflect upon the Qur’an? Had it been from other than Allah, they would have found many contradictions in it. (4:82)
وَقَوْلِهِمْ إِنَّا قَتَلْنَا الْمَسِيحَ عِيسَى ابْنَ مَرْيَمَ رَسُولَ اللَّهِ وَمَا قَتَلُوهُ وَمَا صَلَبُوهُ وَلَٰكِن شُبِّهَ لَهُمْ ۚ وَإِنَّ الَّذِينَ اخْتَلَفُوا فِيهِ لَفِي شَكٍّ مِّنْهُ ۚ مَا لَهُم بِهِ مِنْ عِلْمٍ إِلَّا اتِّبَاعَ الظَّنِّ ۚ وَمَا قَتَلُوهُ يَقِينًا
And their saying, “Indeed, we killed the Messiah, Jesus, the son of Mary, Allah’s Apostle.” And they did not kill him, nor crucify him; though it had appeared to them. And indeed, those who differed about it, are in doubt about it. They have no knowledge in it except following assumption. Surely they did not kill him. (4:157)
When any hadith explicitly opposes the Qur’an, then either that hadith is a forgery, a mistake or perhaps a previous ruling which was abolished.
وَمَا كَانَ الْمُؤْمِنُونَ لِيَنفِرُوا كَافَّةً ۚ فَلَوْلَا نَفَرَ مِن كُلِّ فِرْقَةٍ مِّنْهُمْ طَائِفَةٌ لِّيَتَفَقَّهُوا فِي الدِّينِ وَلِيُنذِرُوا قَوْمَهُمْ إِذَا رَجَعُوا إِلَيْهِمْ لَعَلَّهُمْ يَحْذَرُونَ
And it is not for the believers to set out collectively. So if not, then from every division among them, a ta’ifah set out to gain understanding in the religion and then warn their people when they return. So that perhaps they might beware. (9:122)
A ta’ifah can be a small portion or even a single person. But does this necessarily mean that those who are being warned are always obliged to believe everything this ta’ifah is relaying to them?
يَا أَيُّهَا الَّذِينَ آمَنُوا إِن جَاءَكُمْ فَاسِقٌ بِنَبَإٍ فَتَبَيَّنُوا أَن تُصِيبُوا قَوْمًا بِجَهَالَةٍ فَتُصْبِحُوا عَلَىٰ مَا فَعَلْتُمْ نَادِمِينَ
O ye who have believed, when a fasiq comes to you with information, verify, lest you harm a people out of ignorance and become regretful over what you have done. (49:6)
يَا أَيُّهَا الَّذِينَ آمَنُوا اجْتَنِبُوا كَثِيرًا مِّنَ الظَّنِّ إِنَّ بَعْضَ الظَّنِّ إِثْمٌ ۖ وَلَا تَجَسَّسُوا وَلَا يَغْتَب بَّعْضُكُم بَعْضًا ۚ أَيُحِبُّ أَحَدُكُمْ أَن يَأْكُلَ لَحْمَ أَخِيهِ مَيْتًا فَكَرِهْتُمُوهُ ۚ وَاتَّقُوا اللَّهَ ۚ إِنَّ اللَّهَ تَوَّابٌ رَّحِيمٌ
O ye who have believed, avoid much assumption. Indeed, some assumption is sin. And do not spy nor backbite one another. Would one of you like to eat the flesh of his dead brother? You would hate it. And fear Allah; indeed, Allah is Accepting, Merciful. (49:12)
We know not to accept any narrations from known liars until they have been verified. However, we should not assume that those who have believed are lying without proof, but does this necessarily mean that since someone doesn’t lie, his narrations must always be true?
وَقَالَ لِلَّذِي ظَنَّ أَنَّهُ نَاجٍ مِّنْهُمَا اذْكُرْنِي عِندَ رَبِّكَ فَأَنسَاهُ الشَّيْطَانُ ذِكْرَ رَبِّهِ فَلَبِثَ فِي السِّجْنِ بِضْعَ سِنِينَ
And he said to the one whom he thought would be saved among the two, “Mention me to your lord.” But Satan had made him forget to mention him to his lord. So he was left in prison, several years. (12:42)
وَلَقَدْ عَهِدْنَا إِلَىٰ آدَمَ مِن قَبْلُ فَنَسِيَ وَلَمْ نَجِدْ لَهُ عَزْمًا
And We had already taken a promise from Adam before, but he forgot; and We did not find him to be resolute. (20:115)
All humans have a natural tendency to forget things. It is only by the will and mercy of Allah that He reminds us.
وَاسْتَشْهِدُوا شَهِيدَيْنِ مِن رِّجَالِكُمْ ۖ فَإِن لَّمْ يَكُونَا رَجُلَيْنِ فَرَجُلٌ وَامْرَأَتَانِ مِمَّن تَرْضَوْنَ مِنَ الشُّهَدَاءِ أَن تَضِلَّ إِحْدَاهُمَا فَتُذَكِّرَ إِحْدَاهُمَا الْأُخْرَىٰ ۚ وَلَا يَأْبَ الشُّهَدَاءُ إِذَا مَا دُعُوا ۚ وَلَا تَسْأَمُوا أَن تَكْتُبُوهُ صَغِيرًا أَوْ كَبِيرًا إِلَىٰ أَجَلِهِ ۚ ذَٰلِكُمْ أَقْسَطُ عِندَ اللَّهِ وَأَقْوَمُ لِلشَّهَادَةِ وَأَدْنَىٰ أَلَّا تَرْتَابُوا
And call two witnesses from among your men to testify. And if not two men, then a man and two women from those whose testimony you accept – so if she errs, the other will remind her. And let the witnesses not refuse when they have been called [to testify]. And do not grow weary, that you write it, whether it is small or large, regarding its term. That is more just with Allah and stronger as evidence and more likely that you not have doubt (2:282)
This shows us that having more witnesses and written records of the witnesses’ testimonies will help us to dispel doubts.
