He who believes in Allah and in the last day should honour his guest; he who believes in Allah and in the last day should not harm his neighbor; he who believes in Allah and in the last day should speak good or keep silence. (Using translation from Abū Dāʾūd 5154)   

قَالَ رَسُولُ اللهِ ﷺ مَنْ كَانَ يُؤْمِنُ بِاللهِ وَالْيَوْمِ الْآخِرِ فَلْيُكْرِمْ ضَيْفَهُ وَمَنْ كَانَ يُؤْمِنُ بِاللهِ وَالْيَوْمِ الْآخِرِ فَلَا يُؤْذِي جَارَهُ وَمَنْ كَانَ يُؤْمِنُ بِاللهِ وَالْيَوْمِ الْآخِرِ فَلْيَقُلْ خَيْرًا أَوْ لِيَصْمُتْ  

[Machine] He heard the Messenger of Allah ﷺ saying, "Indeed, a servant may speak a word that he does not realize its consequences, and by it he falls into the Fire, a distance greater than that between the east and the west."  

أَنَّهُ سَمِعَ رَسُولَ اللهِ ﷺ يَقُولُ إِنَّ الْعَبْدَ لَيَتَكَلَّمُ بِالْكَلِمَةِ مَا يَتَبَيَّنُ فِيهَا يَزِلُّ بِهَا فِي النَّارِ أَبْعَدَ مَا بَيْنَ الْمَشْرِقِ وَالْمَغْرِبِ  

The Prophet; said, "A slave (of Allah) may utter a word which pleases Allah without giving it much importance, and because of that Allah will raise him to degrees (of reward): a slave (of Allah) may utter a word (carelessly) which displeases Allah without thinking of its gravity and because of that he will be thrown into the Hell-Fire." (Using translation from Bukhārī 6478)   

عَنِ النَّبِيِّ ﷺ قَالَ إِنَّ الْعَبْدَ لَيَتَكَلَّمُ بِالْكَلِمَةِ مِنْ رِضْوَانِ اللهِ لَا يُلْقِي لَهَا بَالًا يَرْفَعُ اللهُ بِهَا لَهُ دَرَجَاتٍ وَإِنَّ الْعَبْدَ لَيَتَكَلَّمُ بِالْكَلِمَةِ مِنْ سَخَطِ اللهِ لَا يُلْقِي لَهَا بَالًا يَهْوِي بِهَا فِي جَهَنَّمَ  

[Machine] His grandfather said to him, "O Fulan, why do you enter among these people and make them laugh?" For I heard Bilal ibn Al-Harith Al-Muzani, the companion of the Messenger of Allah ﷺ, narrating that the Messenger of Allah ﷺ said, "Indeed, a servant speaks a word that pleases Allah, thinking that it may not reach what it has reached, and Allah is pleased with it on his behalf until the day he meets Him. And indeed, a servant speaks a word that angers Allah, thinking that it may not reach what it has reached, and Allah is angered by it until the day he meets Him.  

لَهُ جَدِّي وَيْحَكَ يَا فُلَانُ لِمَ تَدْخُلُ عَلَى هَؤُلَاءِ فَتُضْحِكَهُمْ؟ فَإِنِّي سَمِعْتُ بِلَالَ بْنَ الْحَارِثِ الْمُزَنِيَّ صَاحِبَ رَسُولِ اللهِ ﷺ يُحَدِّثُ أَنَّ رَسُولَ اللهِ ﷺ قَالَ إِنَّ الْعَبْدَ لَيَتَكَلَّمُ بِالْكَلِمَةِ مِنْ رِضْوَانِ اللهِ مَا يَظُنُّ أَنْ تَبْلُغَ مَا بَلَغَتْ فَيَرْضَى اللهُ بِهَا عَنْهُ إِلَى يَوْمِ يَلْقَاهُ وَإِنَّ الْعَبْدَ لَيَتَكَلَّمُ بِالْكَلِمَةِ مِنْ سَخَطِ اللهِ مَا يَظُنُّ أَنْ تَبْلُغَ مَا بَلَغَتْ فَيَسْخَطُ اللهُ بِهَا إِلَى يَوْمِ يَلْقَاهُ  

[Machine] Indeed, I have seen you entering among these princes and enveloping them, so see what you are explaining to them. For I heard the Messenger of Allah, ﷺ , say: "Indeed, a man may speak a word of goodness without knowing its weight, and Allah writes his satisfaction with it until the day he meets Him. And indeed, a man may speak a word of evil without knowing its weight, and Allah writes His displeasure with him until the day he meets Him." So Alqamah used to say: "Many conversations have taken place between him and me that I have not heard from Bilal."  

لَهُ إِنِّي رَأَيْتُكَ تَدْخُلُ عَلَى هَؤُلَاءِ الْأُمَرَاءِ وَتَغْشَاهُمْ فَانْظُرْ مَاذَا تُحَاضِرُهُمْ بِهِ فَإِنِّي سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ إِنَّ الرَّجُلَ لَيَتَكَلَّمُ بِالْكَلِمَةِ مِنَ الْخَيْرِ مَا يَعْلَمُ مَبْلَغَهَا يَكْتُبُ اللهُ بِهَا رِضْوَانَهُ إِلَى يَوْمِ يَلْقَاهُ وَإِنَّ الرَّجُلَ لَيَتَكَلَّمُ بِالْكَلِمَةِ مِنَ الشَّرِّ مَا يَعْلَمُ مَبْلَغَهَا يَكْتُبُ اللهُ عَلَيْهِ سَخَطَهُ إِلَى يَوْمِ يَلْقَاهُ فَكَانَ عَلْقَمَةُ يَقُولُ رُبَّ حَدِيثٍ قَدْ حَالَ بَيْنِي وَبَيْنَهُ مَا سَمِعْتُ مِنْ بِلَالٍ  

"The Messenger of Allah came out to us, and there were nine of us. He said; 'After me there will be rulers, whoever believes in their lies and helps them in their wrongdoing is not of me, and I am not of him, and he will not come to me at the Cistern. Whoever does not believe their lies and does not help them in their wrongdoing, he is of me, and I am of hi, and he will come to me at the Cistern."' (Using translation from Nasāʾī 4207)   

خَرَجَ عَلَيْنَا رَسُولُ اللهِ ﷺ وَنَحْنُ سَبْعَةٌ أَوْ تِسْعَةٌ وَبَيْنَنَا وَسَائِدُ مِنْ أَدَمٍ أَحْمَرَ قَالَ إِنَّهُ سَيَكُونُ بَعْدِي أُمَرَاءُ فَمَنْ صَدَّقَهُمْ بِكَذِبِهِمْ وَأَعَانَهُمْ عَلَى ظُلْمِهِمْ فَلَيْسَ مِنِّي وَلَسْتُ مِنْهُ وَلَنْ يَرِدَ عَلَيَّ الْحَوْضَ وَمَنْ لَمْ يُصَدِّقْهُمْ بِكَذِبِهِمْ وَلَمْ يُعِنْهُمْ عَلَى ظُلْمِهِمْ فَهُوَ مِنِّي وَأَنَا مِنْهُ وَسَيَرِدُ عَلَيَّ الْحَوْضَ  

[Machine] He said: The Messenger of Allah ﷺ came out to us while we were in the mosque, and I was the ninth of nine. He said to us, "Do you listen? Are you listening?" Three times he said, "It is certain that there will be leaders over you. Whoever visits them and supports them in their wrongdoing, he is not of me and I am not of him. He will not come to my pond on the Day of Resurrection. And whoever visits them and does not support them in their wrongdoing, he is of me and I am of him. He will come to my pond on the Day of Resurrection." He said, "And Sahl bin Saad also narrated to me that the Messenger of Allah ﷺ said to his companions, 'How will you be when you are left in the worst people? People will betray their trust and break their covenants.' They said, 'Then what should we do, O Messenger of Allah?' He said, 'Take what you know and leave what you disapprove of.' Then he specifically addressed Abdullah bin Amr bin Al-As and said, 'What do you command me to do in this situation, O Messenger of Allah?' He said, 'I command you to have Taqwa of Allah in yourself and your affairs in general.'  

أَنَّهُ قَالَ خَرَجَ إِلَيْنَا رَسُولُ اللهِ ﷺ وَنَحْنُ فِي الْمَسْجِدِ أَنَا تَاسِعُ تِسْعَةٍ فَقَالَ لَنَا أَتَسْمَعُونَ؟ هَلْ تَسْمَعُونَ؟ ثَلَاثَ مِرَارٍ إِنَّهَا سَتَكُونُ عَلَيْكُمْ أَئِمَّةٌ فَمَنْ دَخَلَ عَلَيْهِمْ فَصَدَّقَهُمْ بِكَذِبِهِمْ وَأَعَانَهُمْ عَلَى ظُلْمِهِمْ فَلَسْتُ مِنْهُ وَلَيْسَ مِنِّي وَلَا يَرِدُ عَلَيَّ الْحَوْضَ يَوْمَ الْقِيَامَةِ وَمَنْ دَخَلَ عَلَيْهِمْ وَلَمْ يُصَدِّقْهُمْ بِكَذِبِهِمْ وَلَمْ يُعِنْهُمْ عَلَى ظُلْمِهِمْ فَهُوَ مِنِّي وَأَنَا مِنْهُ وَسَيَرِدُ عَلَيَّ الْحَوْضَ يَوْمَ الْقِيَامَةِ قَالَ وَحَدَّثَنِي أَيْضًا عَنْ سَهْلِ بْنِ سَعْدٍ أَنَّ رَسُولَ اللهِ ﷺ قَالَ لِأَصْحَابِهِ كَيْفَ أَنْتُمْ إِذَا بَقِيتُمْ فِي حُثَالَةٍ مِنَ النَّاسِ مَرِجَتْ أَمَانَتُهُمْ وَعُهُودُهُمْ وَكَانُوا هَكَذَا ثُمَّ أَدْخَلَ أَصَابِعَهُ بَعْضَهَا فِي بَعْضٍ فَقَالُوا فَإِذَا كَانَ كَذَلِكَ كَيْفَ نَفْعَلُ يَا رَسُولَ اللهِ؟ قَالَ خُذُوا مَا تَعْرِفُونَ وَدَعُوا مَا تُنْكِرُونَ ثُمَّ خَصَّ بِهَذَا عَبْدَ اللهِ بْنَ عَمْرِو بْنِ الْعَاصِ فِيمَا بَيْنَهُ وَبَيْنَهُ فَقَالَ مَا تَأْمُرُنِي بِهِ يَا رَسُولَ اللهِ إِذَا كَانَ ذَلِكَ؟ قَالَ آمُرُكَ بِتَقْوَى اللهِ عَلَيْكَ بِنَفْسِكَ وَإِيَّاكَ وَعَامَّةَ الْأُمُورِ  

[Machine] "That the truth is other than him, so we believe them and they judge with injustice, so we strengthen them and improve it for them. So how do you see that? He said, 'O son of my brother, we were with the Messenger of Allah ﷺ counting this hypocrisy, so I do not know how it is with you.'"  

أَنَّ الْحَقَّ غَيْرُهُ فَنَصْدُقُهُمْ وَيَقْضُونَ بِالْجَوْرِ فَنُقَوِّيهِمْ وَنُحَسِّنُهُ لَهُمْ فَكَيْفَ تَرَى فِي ذَلِكَ؟ فَقَالَ يَا ابْنَ أَخِي كُنَّا مَعَ رَسُولِ اللهِ ﷺ نَعُدُّ هَذَا النِّفَاقَ فَلَا أَدْرِي كَيْفَ هُوَ عِنْدَكُمْ  

[Machine] "The Messenger of Allah ﷺ said, 'Whoever guarantees for me what is between his beard and his ankles, I guarantee for him Paradise.'"  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ مَنْ يَضْمَنُ لِي مَا بَيْنَ لَحْيَيْهِ وَمَا بَيْنَ رِجْلَيْهِ أَضْمَنُ لَهُ الْجَنَّةَ
