[Machine] I heard the Messenger of Allah ﷺ saying, "Whoever loves the Ansar, Allah will love him, and whoever hates the Ansar, Allah will hate him."  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «مَنْ أَحَبَّ الْأَنْصَارَ أَحَبَّهُ اللهُ وَمَنْ أَبْغَضَ الْأَنْصَارَ أَبْغَضَهُ اللهُ»  

A person who believes in Allah and the Last Day never nurses a grudge against the Ansar. (Using translation from Muslim 76)  

قَالَ رَسُولُ اللهِ ﷺ «لَا يَبْغَضُ الْأَنْصَارَ رَجُلٌ يُؤْمِنْ بِاللهِ وَالْيَوْمِ الْآخِرِ»  

"None but the believer loves them, none but the hypocrite hates them. He who loves them loves Allah and he who hates them hates Allah." I (the narrator) said: Did you hear this hadith from al-Bara'? He said: He narrated it to me. (Using translation from Muslim 75)   

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «فِي الْأَنْصَارِ لَا يُحِبُّهُمْ إِلَّا مُؤْمِنٌ وَلَا يَبْغَضُهُمْ إِلَّا كَافِرٌ مَنْ أَحَبَّهُمْ أَحَبَّهُ اللهُ وَمَنْ أَبْغَضَهُمْ أَبْغَضَهُ اللهُ» قَالَ شُعْبَةُ قُلْتُ لِعَدِيٍّ أَنْتَ سَمِعْتَ هَذَا مِنَ الْبَرَاءِ قَالَ «إِيَّايَ حَدَّثَ»  

When Allah favored His Apostle with the properties of Hawazin tribe as Fai (booty), he started giving to some Quarries men even up to one-hundred camels each, whereupon some Ansari men said about Messenger of Allah ﷺ, "May Allah forgive His Apostle! He is giving to (men of) Quraish and leaves us, in spite of the fact that our swords are still dropping blood (of the infidels)" When Messenger of Allah ﷺ was informed of what they had said, he called the Ansar and gathered them in a leather tent and did not call anybody else along, with them. When they gathered, Messenger of Allah ﷺ came to them and said, "What is the statement which, I have been informed, and that which you have said?" The learned ones among them replied," O Messenger of Allah ﷺ! The wise ones amongst us did not say anything, but the youngsters amongst us said, 'May Allah forgive His Apostle; he gives the Quarish and leaves the Ansar, in spite of the fact that our swords are still dribbling (wet) with the blood of the infidels.' " Messenger of Allah ﷺ replied, I give to such people as are still close to the period of Infidelity (i.e. they have recently embraced Islam and Faith is still weak in their hearts). Won't you be pleased to see people go with fortune, while you return with Messenger of Allah ﷺ to your houses? By Allah, what you will return with, is better than what they are returning with." The Ansar replied, "Yes, O Messenger of Allah ﷺ, we are satisfied' Then the Prophet ﷺ said to them." You will find after me, others being preferred to you. Then be patient till you meet Allah and meet His Apostle at Al-Kauthar (i.e. a fount in Paradise)." (Anas added:) But we did not remain patient. (Using translation from Bukhārī 3147)   

أَنَّهُ قَالَ لَمَّا أَفَاءَ اللهُ عَلَى رَسُولِهِ مَا أَفَاءَ مِنْ أَمْوَالِ هَوَازِنَ طَفِقَ رَسُولُ اللهِ ﷺ يُعْطِي رِجَالًا مِنْ قُرَيْشٍ الْمِائَةَ مِنَ الْإِبِلِ فَقَالَ رَجُلٌ مِنَ الْأَنْصَارِ يَغْفِرُ اللهُ لِرَسُولِ اللهِ ﷺ يُعْطِي قُرَيْشًا وَيَتْرُكُنَا وَسُيُوفُنَا تَقْطُرُ مِنْ دِمَائِهِمْ قَالَ أَنَسٌ «فَبَلَغَ ذَلِكَ رَسُولَ اللهِ ﷺ فَأَرْسَلَ إِلَى الْأَنْصَارِ فَجَمَعَهُمْ فِي قُبَّةٍ مِنْ أَدَمٍ وَلَمْ يَدَعْ مَعَهُمْ أَحَدًا فَلَمَّا اجْتَمَعُوا» قَالَ «مَا حَدِيثٌ بَلَغَنِي عَنْكُمْ؟» قَالَ فُقَهَاءُ الْأَنْصَارِ أَمَّا ذَوُو الرَّأْيِ مِنَّا فَلَمْ يَقُولُوا شَيْئًا وَإِنَّمَا أُنَاسٌ حَدِيثَةٌ أَسْنَانُهُمْ فَقَالُوا «يَغْفِرُ اللهُ لِرَسُولِ اللهِ ﷺ يُعْطِي قُرَيْشًا وَيَتْرُكُنَا وَسُيُوفُنَا تَقْطُرُ مِنْ دِمَائِهِمْ» فَقَالَ رَسُولُ اللهِ ﷺ «إِنِّي لَأُعْطِي رِجَالًا حَدِيثٌ عَهْدُهُمْ بِالْكُفْرِ فَأَتَأَلَّفُهُمْ أَفَلَا تَرْضَوْنَ أَنْ يَذْهَبَ النَّاسُ بِالْأَمْوَالِ وَتَرْجِعُونَ إِلَى رِحَالِكُمْ بِرَسُولِ اللهِ ﷺ؟ فَوَاللهِ لَمَا تَنْقَلِبُونَ بِهِ خَيْرٌ مِمَّا يَنْقَلِبُونَ بِهِ» قَالُوا بَلَى يَا رَسُولَ اللهِ قَدْ رَضِينَا فَقَالَ لَهُمْ «إِنَّكُمْ سَتَلْقَوْنَ بَعْدِي أَثَرَةً شَدِيدَةً فَاصْبِرُوا حَتَّى تَلْقَوُا اللهَ وَرَسُولَهُ عَلَى الْحَوْضِ» قَالَ أَنَسٌ «فَلَمْ نَصْبِرْ»
