Messenger of Allah ﷺ narrated to us two narrations, one of which I have seen (happening) and I am waiting for the other. He narrated that honesty was preserved in the roots of the hearts of men (in the beginning) and then they learnt it (honesty) from the Qur'an, and then they learnt it from the (Prophet's) Sunna (tradition). He also told us about its disappearance, saying, "A man will go to sleep whereupon honesty will be taken away from his heart, and only its trace will remain, resembling the traces of fire. He then will sleep whereupon the remainder of the honesty will also be taken away (from his heart) and its trace will resemble a blister which is raised over the surface of skin, when an ember touches one's foot; and in fact, this blister does not contain anything. So there will come a day when people will deal in business with each other but there will hardly be any trustworthy persons among them. Then it will be said that in such-and-such a tribe there is such-and-such person who is honest, and a man will be admired for his intelligence, good manners and strength, though indeed he will not have belief equal to a mustard seed in his heart."

The narrator added: There came upon me a time when I did not mind dealing with anyone of you, for if he was a Muslim, his religion would prevent him from cheating; and if he was a Christian, his Muslim ruler would prevent him from cheating; but today I cannot deal except with so-and-so and so-and-so.

حَدَّثَنَا رَسُولُ اللهِ ﷺ بِحَدِيثَيْنِ وَقَدْ رَأَيْتُ أَحَدَهُمَا وَأَنَا أَنْتَظِرُ الْآخَرَ حَدَّثَنَا أَنَّ الْأَمَانَةَ نَزَلَتْ فِي جَذْرِ قُلُوبِ الرِّجَالِ فَنَزَلَ الْقُرْآنُ فَعَلِمُوا مِنَ الْقُرْآنِ وَعَلِمُوا مِنَ السُّنَّةِ ثُمَّ حَدَّثَنَا عَنَ رَفْعِهَا فَقَالَ يَنَامُ الرَّجُلُ نَوْمَةً فَتُقْبَضُ الْأَمَانَةُ مِنْ قَلْبِهِ فَيَبْقَى أَثَرُهَا مِثْلَ أَثَرِ الْوَكْتِ ثُمَّ يَنَامُ الرَّجُلُ نَوْمَةً فَتُقْبَضُ الْأَمَانَةُ مِنْ قَلْبِهِ فَيَبْقَى أَثَرُهَا مِثْلَ أَثَرِ الْمَجْلِ كَجَمْرٍ دَحْرَجْتَهُ عَلَى رِجْلِكَ فَنَفِطَ فَتَرَاهُ مُنْتَبِرًا وَلَيْسَ فِيهِ شَيْءٌ فَيُصْبِحُ النَّاسُ يَتَبَايَعُونَ وَلَا يَكَادُ أَحَدٌ يُؤَدِّي حَتَّى يُقَالَ إِنَّ فِي بَنِي فُلَانٍ رَجُلًا أَمِينًا وَحَتَّى يُقَالَ لِرَجُلٍ مَا أَجْلَدَهُ وَأَظْرَفَهُ وَأَعْقَلَهُ وَلَيْسَ فِي قَلْبِهِ مِثْقَالُ حَبَّةِ خَرْدَلٍ مِنْ خَيْرٍ قَالَ حُذَيْفَةُ ؓ وَلَقَدْ أَتَى عَلَيَّ زَمَانٌ وَمَا أُبَالِي أَيُّكُمْ بَايَعْتُهُ لَئِنْ كَانَ مُؤْمِنًا لَيَرُدَّنَّ عَلَيَّ دِينُهُ وَلَئِنْ كَانَ يَهُودِيًّا أَوْ نَصْرَانِيًّا لَيَرُدَّنَّ عَلَيَّ سَاعِيهِ فَأَمَّا الْيَوْمُ فَمَا كُنْتُ أُبَايِعُ إِلَّا فُلَانًا وَفُلَانًا لَفْظُ حَدِيثِ أَبِي صَالِحٍ  

[Machine] On the authority of the Prophet ﷺ, he said: "The righteous ones will depart one after another, until only a handful will remain, like a handful of barley or dates, and Allah will not care about them at all."  

عَنِ النَّبِيِّ ﷺ قَالَ يَذْهَبُ الصَّالِحُونَ الْأَوَّلُ فَالْأَوَّلُ وَيَبْقَى حُفَالَةٌ مِثْلُ حُفَالَةِ الشَّعِيرِ أَوِ التَّمْرِ وَلَا يُبَالِيهِمُ اللهُ بَالًا  

The Prophet ﷺ said, "The best people are those of my generation, and then those who will come after them (the next generation), and then those who will come after them (i.e. the next generation), and then after them, there will come people whose witness will precede their oaths, and whose oaths will precede their witness." (Using translation from Bukhārī 6429)   

قَالَ رَسُولُ اللهِ ﷺ خَيْرُ النَّاسِ قَرْنِي ثُمَّ الَّذِينَ يَلُونَهُمْ ثُمَّ الَّذِينَ يَلُونَهُمْ ثُمَّ يَجِيءُ قَوْمٌ تَسْبِقُ أَيْمَانُهُمْ شَهَادَتَهُمْ وَشَهَادَتُهُمْ أَيْمَانَهُمْ  

I heard ʿImran bin Husain saying, "The Prophet ﷺ said, 'The best people are those living in my generation, then those coming after them, and then those coming after (the second generation)." ʿImran said "I do not know whether the Prophet ﷺ mentioned two or three generations after your present generation. The Prophet ﷺ added, 'There will be some people after you, who will be dishonest and will not be trustworthy and will give witness (evidences) without being asked to give witness, and will vow but will not fulfill their vows, and obesity will appear among them." (Using translation from Bukhārī 2651)   

قَالَ رَسُولُ اللهِ ﷺ خَيْرُكُمْ قَرْنِي ثُمَّ الَّذِينَ يَلُونَهُمْ ثُمَّ الَّذِينَ يَلُونَهُمْ ثُمَّ الَّذِينَ يَلُونَهُمْ قَالَ عِمْرَانُ بْنُ حُصَيْنٍ لَا أَدْرِي أَذَكَرَ رَسُولُ اللهِ ﷺ بَعْدَ قَرْنِهِ قَرْنَيْنِ أَوْ ثَلَاثَةً ثُمَّ قَالَ رَسُولُ اللهِ ﷺ إِنَّ بَعْدَكُمْ قَوْمًا يَخُونُونَ وَلَا يُؤْتَمَنُونَ وَيَشْهَدُونَ وَلَا يُسْتَشْهَدُونَ وَيَنْذِرُونَ وَلَا يَفُونَ وَيَظْهَرُ فِيهِمُ السِّمَنُ
