[Machine] Indeed, we have pledged allegiance to this man for the sake of Allah and His Messenger. And verily, I heard the Messenger of Allah ﷺ say: "Indeed, the treacherous person will have a flag raised for him on the Day of Resurrection, and it will be said: 'This is the treachery of so-and-so.' And indeed, one of the greatest forms of treachery after associating partners with Allah is for a person to pledge allegiance to another person for the sake of Allah and His Messenger, and then he breaks his allegiance. And neither should any of you fight with others to gain power nor should one of you envy others in this matter, for it will lead to division between me and him."  

إِنَّا بَايَعْنَا هَذَا الرَّجُلَ عَلَى بَيْعَةِ اللهِ وَرَسُولِهِ وَإِنِّي سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ إِنَّ الْغَادِرَ يُنْصَبُ لَهُ لِوَاءٌ يَوْمَ الْقِيَامَةِ فَيُقَالُ هَذِهِ غَدْرَةُ فُلَانٍ وَإِنَّ مِنْ أَعْظَمِ الْغَدْرِ بَعْدَ الْإِشْرَاكِ بِاللهِ أَنْ يُبَايِعَ رَجُلٌ رَجُلًا عَلَى بَيْعِ اللهِ وَرَسُولِهِ ثُمَّ يَنْكُثُ بَيْعَتَهُ وَلَا يَخْلَعَنَّ أَحَدٌ مِنْكُمْ يَزِيدَ وَلَا يَشْرُفَنَّ أَحَدٌ مِنْكُمْ فِي هَذَا الْأَمْرِ فَيَكُونَ صَيْلَمًا بَيْنِي وَبَيْنَهُ  

أَتَرَوْنَ هَذَا أَرَادَ؟ إِنَّ دِينِي إِذًا عِنْدِي لَرَخِيصٌ زَادَ فِيهِ غَيْرُهُ فَلَمَّا مَاتَ مُعَاوِيَةُ وَاجْتَمَعَ النَّاسُ عَلَى يَزِيدَ بَايَعَهُ  

When the people of Medina dethroned Yazid bin Muawiya, Ibn ʿUmar gathered his special friends and children and said, "I heard the Prophet ﷺ saying, 'A flag will be fixed for every betrayer on the Day of Resurrection,' and we have given the oath of allegiance to this person (Yazid) in accordance with the conditions enjoined by Allah and His Apostle and I do not know of anything more faithless than fighting a person who has been given the oath of allegiance in accordance with the conditions enjoined by Allah and His Apostle , and if ever I learn that any person among you has agreed to dethrone Yazid, by giving the oath of allegiance (to somebody else) then there will be separation between him and me." (Using translation from Bukhārī 7111)   

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ يُنْصَبُ لِكُلِّ غَادِرٍ لِوَاءٌ يَوْمَ الْقِيَامَةِ زَادَ الزَّهْرَانِيُّ فِي رِوَايَتِهِ قَالَ وَإِنَّا قَدْ بَايَعْنَا هَذَا الرَّجُلَ عَلَى بَيْعَةِ اللهِ وَرَسُولِهِ وَإِنِّي لَا أَعْلَمُ غَدْرًا أَعْظَمَ مِنْ أَنْ تُبَايِعَ رَجُلًا عَلَى بَيْعَةِ اللهِ وَرَسُولِهِ ثُمَّ تَنْصِبَ لَهُ الْقِتَالَ إِنِّي لَا أَعْلَمُ أَحَدًا مِنْكُمْ خَلَعَ وَلَا بَايَعَ فِي هَذَا الْأَمْرِ إِلَّا كَانَتِ الْفَيْصَلَ فِيمَا بَيْنِي وَبَيْنَهُ  

[Machine] "From the Prophet ﷺ , he said: For every betrayer, there will be a banner on the Day of Judgment. One of them will be raised and the other will be exposed, and on the Day of Judgment, he will be identified by it."  

عَنِ النَّبِيِّ ﷺ قَالَ لِكُلِّ غَادِرٍ لِوَاءٌ يَوْمَ الْقِيَامَةِ قَالَ أَحَدُهُمَا يُنْصَبُ وَقَالَ الْآخَرُ يُرَى يَوْمَ الْقِيَامَةِ يُعْرَفُ بِهِ  

On the Day of Judgment there will be a flag for every person guilty of the breach of faith. It will be raised in proportion to the extent of his guilt; and there is no guilt of treachery more serious than the one committed by the ruler of men. (Using translation from Muslim 1738b)   

قَالَ رَسُولُ اللهِ ﷺ لِكُلِّ غَادِرٍ لِوَاءٌ يَوْمَ الْقِيَامَةِ يُرْفَعُ لَهُ بِقَدْرِ غَدْرَتِهِ أَلَا وَلَا غَادِرَ أَعْظَمَ غَدْرًا مِنْ أَمِيرِ عَامَّةٍ  

Messenger of Allah ﷺ said, "There are three persons whom Allah will not look at on the Day of Resurrection, nor will he purify them and theirs shall be a severe punishment. They are: -1. A man possessed superfluous water, on a way and he withheld it from travelers. -2. A man who gave a pledge of allegiance to a ruler and he gave it only for worldly benefits. If the ruler gives him something he gets satisfied, and if the ruler withholds something from him, he gets dissatisfied. -3. And man displayed his goods for sale after the ʿAsr prayer and he said, 'By Allah, except Whom None has the right to be worshipped, I have been given so much for my goods,' and somebody believes him (and buys them). The Prophet ﷺ then recited: "Verily! Those who purchase a little gain at the cost of Allah's Covenant and their oaths." (3.77) (Using translation from Bukhārī 2358)   

قَالَ رَسُولُ اللهِ ﷺ ثَلَاثَةٌ لَا يَنْظُرُ اللهُ إِلَيْهِمْ يَوْمَ الْقِيَامَةِ وَلَا يُزَكِّيهِمْ وَلَهُمْ عَذَابٌ أَلِيمٌ رَجُلٌ كَانَ لَهُ فَضْلُ مَاءٍ فِي الطَّرِيقِ فَمَنَعَهُ مِنِ ابْنِ السَّبِيلِ وَرَجُلٌ بَايَعَ إِمَامًا لَا يُبَايِعُهُ إِلَّا لِلدُّنْيَا فَإِنْ أَعْطَاهُ مِنْهَا رَضِيَ وَإِنْ لَمْ يُعْطِهِ مِنْهَا سَخِطَ وَرَجُلٌ أَقَامَ سِلْعَةً بَعْدَ الْعَصْرِ فَقَالَ وَاللهِ الَّذِي لَا إِلَهَ إِلَّا هُوَ لَقَدْ أَعْطَيْتُ بِهَا كَذَا وَكَذَا فَصَدَّقَهُ الرَّجُلُ وَاشْتَرَاهَا مِنْهُ ثُمَّ قَرَأَ هَذِهِ الْآيَةَ {إِنَّ الَّذِينَ يَشْتَرُونَ بِعَهْدِ اللهِ وَأَيْمَانِهِمْ ثَمَنًا قَلِيلًا} [آل عمران 77] إِلَى آخِرِ الْآيَةِ
