Some people asked Messenger of Allah ﷺ, "Whose Islam is the best? i.e. (Who is a very good Muslim)?" He replied, "One who avoids harming the Muslims with his tongue and hands."  

قَالُوا يَا رَسُولَ اللَّهِ أَىُّ الإِسْلاَمِ أَفْضَلُ قَالَ مَنْ سَلِمَ الْمُسْلِمُونَ مِنْ لِسَانِهِ وَيَدِهِ  

Messenger of Allah ﷺ said, "Whoever can guarantee (the chastity of) what is between his two jaw-bones and what is between his two legs (i.e. his tongue and his private parts), I guarantee Paradise for him."  

عَنْ رَسُولِ اللَّهِ ﷺ قَالَ مَنْ يَضْمَنْ لِي مَا بَيْنَ لَحْيَيْهِ وَمَا بَيْنَ رِجْلَيْهِ أَضْمَنْ لَهُ الْجَنَّةَ  

That he heard Messenger of Allah ﷺ saying, "A slave of Allah may utter a word without thinking whether it is right or wrong, he may slip down in the Fire as far away a distance equal to that between the east."  

سَمِعَ رَسُولَ اللَّهِ ﷺ يَقُولُ إِنَّ الْعَبْدَ لَيَتَكَلَّمُ بِالْكَلِمَةِ مَا يَتَبَيَّنُ فِيهَا يَزِلُّ بِهَا فِي النَّارِ أَبْعَدَ مِمَّا بَيْنَ الْمَشْرِقِ  

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."  

عَنِ النَّبِيِّ ﷺ قَالَ إِنَّ الْعَبْدَ لَيَتَكَلَّمُ بِالْكَلِمَةِ مِنْ رِضْوَانِ اللَّهِ لاَ يُلْقِي لَهَا بَالاً يَرْفَعُ اللَّهُ بِهَا دَرَجَاتٍ وَإِنَّ الْعَبْدَ لَيَتَكَلَّمُ بِالْكَلِمَةِ مِنْ سَخَطِ اللَّهِ لاَ يُلْقِي لَهَا بَالاً يَهْوِي بِهَا فِي جَهَنَّمَ  

I said: "O Messenger of Allah! Inform me about a matter that I may hold fast to." He said: 'Say: My Lord is Allah, then be steadfast.' I said: "O Messenger of Allah! What do you fear most for me?" So he took hold of his tongue and said: 'This.'"  

قُلْتُ يَا رَسُولَ اللَّهِ حَدِّثْنِي بِأَمْرٍ أَعْتَصِمُ بِهِ قَالَ قُلْ رَبِّيَ اللَّهُ ثُمَّ اسْتَقِمْ قُلْتُ يَا رَسُولَ اللَّهِ مَا أَخْوَفُ مَا تَخَافُ عَلَىَّ فَأَخَذَ بِلِسَانِ نَفْسِهِ ثُمَّ قَالَ هَذَا  

"Do not talk too much without remembrance of Allah. Indeed excessive talking without remembrance of Allah hardens the heart. And indeed the furthest of people from Allah is the harsh-hearted."  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ تُكْثِرُوا الْكَلاَمَ بِغَيْرِ ذِكْرِ اللَّهِ فَإِنَّ كَثْرَةَ الْكَلاَمِ بِغَيْرِ ذِكْرِ اللَّهِ قَسْوَةٌ لِلْقَلْبِ وَإِنَّ أَبْعَدَ النَّاسِ مِنَ اللَّهِ الْقَلْبُ الْقَاسِي حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي النَّضْرِ حَدَّثَنِي أَبُو النَّضْرِ عَنْ إِبْرَاهِيمَ بْنِ عَبْدِ اللَّهِ بْنِ حَاطِبٍ عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ عَنِ ابْنِ عُمَرَ عَنِ النَّبِيِّ ﷺ نَحْوَهُ بِمَعْنَاهُ  

"For whomever Allah protects against the evil of what is between his jaws and the evil of what is between his legs, he shall enter Paradise."  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ وَقَاهُ اللَّهُ شَرَّ مَا بَيْنَ لَحْيَيْهِ وَشَرَّ مَا بَيْنَ رِجْلَيْهِ دَخَلَ الْجَنَّةَ  

"I said: 'O Messenger of Allah! What is the means to salvation?' He said: 'That you control your tongue, suffice yourself your house, and cry over your sins.'"  

قُلْتُ يَا رَسُولَ اللَّهِ مَا النَّجَاةُ قَالَ أَمْسِكْ عَلَيْكَ لِسَانَكَ وَلْيَسَعْكَ بَيْتُكَ وَابْكِ عَلَى خَطِيئَتِكَ  

I accompanied the Prophet ﷺ on a journey. One day I was near him while we were moving so I said: "O Messenger of Allah! Inform me about an action by which I will be admitted into Paradise, and which will keep me far from the Fire." He said: "You have asked me about something great, but it is easy for whomever Allah makes it easy: (1) Worship Allah and do not associate any partners with Him, (2) establish the Salah, (3) give the Zakat, (4) fast Ramadan and, (5) perform Hajj to the House.'

Then he ﷺ said: "Shall I not guide you to the doors of good? (1) Fasting is a shield, and (2) charity extinguishes sins like water extinguishes fire, and (3) a person's prayer in depths of the night." Then he ﷺ recited: "Their sides forsake their beds to call upon their Lord..." until he reached "what they used to do." [Sajdah 32:16-17]

Then he ﷺ said: "Shall I not inform you about the head of the entire matter, and its pillar, and its hump?" I said: "Of course, O Messenger of Allah!" He ﷺ said: "The head of the matter is Islam, and its pillar is the Salah, and its hump is Jihad."

Then he ﷺ said: "Shall I not inform you about what governs all of that?" I said: "Of course, O Messenger of Allah!" So he ﷺ grabbed his tongue and he said: "Restrain this." I said: "O Prophet of Allah! Will we be taken to account for what we say?" He said: "May your mother grieve your loss O Muadh! Are the people not tossed into the Hellfire upon their faces," or "upon their noses, except because of what their tongues have wrought?"  

كُنْتُ مَعَ النَّبِيِّ ﷺ فِي سَفَرٍ فَأَصْبَحْتُ يَوْمًا قَرِيبًا مِنْهُ وَنَحْنُ نَسِيرُ فَقُلْتُ يَا رَسُولَ اللَّهِ أَخْبِرْنِي بِعَمَلٍ يُدْخِلُنِي الْجَنَّةَ وَيُبَاعِدُنِي مِنَ النَّارِ قَالَ: «لَقَدْ سَأَلْتَنِي عَنْ عَظِيمٍ، وَإِنَّهُ لَيَسِيرٌ عَلَى مَنْ يَسَّرَهُ اللَّهُ عَلَيْهِ: (١) تَعْبُدُ اللَّهَ وَلاَ تُشْرِكُ بِهِ شَيْئًا، (٢) وَتُقِيمُ الصَّلاَةَ، (٣) وَتُؤْتِي الزَّكَاةَ، (٤) وَتَصُومُ رَمَضَانَ، (٥) وَتَحُجُّ الْبَيْتَ۔»

ثُمَّ قَالَ: «أَلاَ أَدُلُّكَ عَلَى أَبْوَابِ الْخَيْرِ؟ (١) الصَّوْمُ جُنَّةٌ، (٢) وَالصَّدَقَةُ تُطْفِئُ الْخَطِيئَةَ كَمَا يُطْفِئُ الْمَاءُ النَّارَ، (٣) وَصَلاَةُ الرَّجُلِ مِنْ جَوْفِ اللَّيْلِ۔» قَالَ ثُمَّ تَلاََ {تَتَجَافَى جُنُوبُهُمْ عَنِ الْمَضَاجِعِ} حَتَّى بَلَغَ {يَعْمَلُونَ} [السجدة 16-17]»

ثُمَّ قَالَ: «أَلاَ أُخْبِرُكَ بِرَأْسِ الأَمْرِ كُلِّهِ وَعَمُودِهِ وَذِرْوَةِ سَنَامِهِ؟» قُلْتُ: بَلَى يَا رَسُولَ اللَّهِ قَالَ: «رَأْسُ الأَمْرِ الإِسْلاَمُ وَعَمُودُهُ الصَّلاَةُ وَذِرْوَةُ سَنَامِهِ الْجِهَادُ۔»

ثُمَّ قَالَ: «أَلاَ أُخْبِرُكَ بِمَلاَكِ ذَلِكَ كُلِّهِ؟ قُلْتُ: بَلَى يَا نَبِيَّ اللَّهِ قَالَ فَأَخَذَ بِلِسَانِهِ قَالَ: «كُفَّ عَلَيْكَ هَذَا۔» فَقُلْتُ يَا نَبِيَّ اللَّهِ، وَإِنَّا لَمُؤَاخَذُونَ بِمَا نَتَكَلَّمُ بِهِ؟ فَقَالَ: «ثَكِلَتْكَ أُمُّكَ يَا مُعَاذُ، وَهَلْ يَكُبُّ النَّاسَ فِي النَّارِ عَلَى وُجُوهِهِمْ» أَوْ «عَلَى مَنَاخِرِهِمْ إِلاَّ حَصَائِدُ أَلْسِنَتِهِمْ؟»  

Do you know what is backbiting? They (the Companions) said: Allah and His Messenger know best. Thereupon he (the Holy Prophet) said: Backbiting implies your talking about your brother in a manner which he does not like. It was said to him: What is your opinion about this that if I actually find (that failing) in my brother which I made a mention of? He said: If (that failing) is actually found (in him) what you assert, you in fact backbited him, and if that is not in him it is a slander.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ أَتَدْرُونَ مَا الْغِيبَةُ قَالُوا اللَّهُ وَرَسُولُهُ أَعْلَمُ قَالَ ذِكْرُكَ أَخَاكَ بِمَا يَكْرَهُ قِيلَ أَفَرَأَيْتَ إِنْ كَانَ فِي أَخِي مَا أَقُولُ قَالَ إِنْ كَانَ فِيهِ مَا تَقُولُ فَقَدِ اغْتَبْتَهُ وَإِنْ لَمْ يَكُنْ فِيهِ فَقَدْ بَهَتَّهُ  

“The Messenger of Allah ﷺ said, during the Farewell Pilgrimage: ‘Is not the most sacred of your days this day, is not the most sacred of your months this month, is not the most sacred of your lands this land? Your blood and your wealth are as sacred to you as this day of yours in this month of yours. Have I not conveyed (the message)?’ They said: ‘Yes.” He said: ‘O Allah, bear witness.’”  

قَالَ رَسُولُ اللَّهِ ﷺ فِي حِجَّةِ الْوَدَاعِ أَلاَ إِنَّ أَحْرَمَ الأَيَّامِ يَوْمُكُمْ هَذَا أَلاَ وَإِنَّ أَحْرَمَ الشُّهُورِ شَهْرُكُمْ هَذَا أَلاَ وَإِنَّ أَحْرَمَ الْبَلَدِ بَلَدُكُمْ هَذَا أَلاَ وَإِنَّ دِمَاءَكُمْ وَأَمْوَالَكُمْ عَلَيْكُمْ حَرَامٌ كَحُرْمَةِ يَوْمِكُمْ هَذَا فِي شَهْرِكُمْ هَذَا فِي بَلَدِكُمْ هَذَا أَلاَ هَلْ بَلَّغْتُ قَالُوا نَعَمْ قَالَ اللَّهُمَّ اشْهَدْ  

I said to the Prophet ﷺ: It is enough for you in Safiyyah that she is such and such (the other version than Musaddad's has:) meaning that she was short-statured. He replied; You have said a word which would change the sea if it were mixed in it. She said: I imitated a man before him (out of disgrace). He said: I do not like that I imitate anyone even if I should get such and such.  

قُلْتُ لِلنَّبِيِّ ﷺ حَسْبُكَ مِنْ صَفِيَّةَ كَذَا وَكَذَا قَالَ غَيْرُ مُسَدَّدٍ تَعْنِي قَصِيرَةً فَقَالَ لَقَدْ قُلْتِ كَلِمَةً لَوْ مُزِجَتْ بِمَاءِ الْبَحْرِ لَمَزَجَتْهُ قَالَتْ وَحَكَيْتُ لَهُ إِنْسَانًا فَقَالَ مَا أُحِبُّ أَنِّي حَكَيْتُ إِنْسَانًا وَأَنَّ لِي كَذَا وَكَذَا  

The Prophet ﷺ said: When I was taken up to heaven I passed by people who had nails of copper and were scratching their faces and their breasts. I said: Who are these people, Gabriel? He replied: They are those who were given to back biting and who aspersed people's honour. Abu Dawud said: Yahya b. 'Uthman has also transmitted it from Baqiyyah, there is no mention of Anas in it.  

قَالَ رَسُولُ اللَّهِ ﷺ لَمَّا عُرِجَ بِي مَرَرْتُ بِقَوْمٍ لَهُمْ أَظْفَارٌ مِنْ نُحَاسٍ يَخْمِشُونَ وُجُوهَهُمْ وَصُدُورَهُمْ فَقُلْتُ مَنْ هَؤُلاَءِ يَا جِبْرِيلُ قَالَ هَؤُلاَءِ الَّذِينَ يَأْكُلُونَ لُحُومَ النَّاسِ وَيَقَعُونَ فِي أَعْرَاضِهِمْ  

Everything of a Muslim is sacred to a Muslim : his property, honour and blood. It is enough evil for any man to despise his brother Muslim.  

قَالَ رَسُولُ اللَّهِ ﷺ كُلُّ الْمُسْلِمِ عَلَى الْمُسْلِمِ حَرَامٌ مَالُهُ وَعِرْضُهُ وَدَمُهُ حَسْبُ امْرِئٍ مِنَ الشَّرِّ أَنْ يَحْقِرَ أَخَاهُ الْمُسْلِمَ  

“The whole of the Muslim is sacred to his fellow Muslim, his blood, his wealth and his honor.”  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ كُلُّ الْمُسْلِمِ عَلَى الْمُسْلِمِ حَرَامٌ دَمُهُ وَمَالُهُ وَعِرْضُهُ
