that the Messenger of Allah ﷺ said: "When Allah loves a slave He calls Jibra'il, (saying): 'Indeed I love so-and-so, so love him.'" He said: "So he calls out in the heavens. Then love for him descends among the people of the earth. That is as in the saying of Allah: Verily, those who believe and work deeds of righteousness, the Most Gracious will grant love for them (19:96). And when Allah hates a slave He calls out to Jibra'il, (saying): 'Indeed I hate so-and-so.' So he calls out in the heavens. Then hatred for him descends upon the earth.'" (Using translation from Tirmidhī 3161)   

السيوطي:١٠١٥a –

"إذا أحبَّ الله ﷻ عبدًا نادى جبريل: إنى قد أحببت فلانًا فأحبه فينادى في السماء، ثم تنْزل له المحبةُ في أهلِ الأرض فذلك قول الله تعالى: {إِنَّ الَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ سَيَجْعَلُ لَهُمُ الرَّحْمَنُ وُدًّا} وإذا أبغض الله عبدًا نادى جبريل: إنى قد أبغضت فلانًا، فينادى في السماءِ، ثم تنْزل له البغضاء في الأرض".

الترمذي:٣١٦١ – حَدَّثَنَا قُتَيْبَةُ حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ مُحَمَّدٍ عَنْ سُهَيْلِ بْنِ أَبِي صَالِحٍ عَنْ أَبِيهِ عَنْ أَبِي هُرَيْرَةَ

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا أَحَبَّ اللَّهُ عَبْدًا نَادَى جِبْرِيلَ إِنِّي قَدْ أَحْبَبْتُ فُلاَنًا فَأَحِبَّهُ قَالَ فَيُنَادِي فِي السَّمَاءِ ثُمَّ تَنْزِلُ لَهُ الْمَحَبَّةُ فِي أَهْلِ الأَرْضِ فَذَلِكَ قَوْلُ اللَّهِ ( إنَّ الَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ سَيَجْعَلُ لَهُمُ الرَّحْمَنُ وُدًّا ) وَإِذَا أَبْغَضَ اللَّهُ عَبْدًا نَادَى جِبْرِيلَ إِنِّي قَدْ أَبْغَضْتُ فُلاَنًا فَيُنَادِي فِي السَّمَاءِ ثُمَّ تَنْزِلُ لَهُ الْبَغْضَاءُ فِي الأَرْضِ  

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ وَقَدْ رَوَى عَبْدُ الرَّحْمَنِ بْنُ عَبْدِ اللَّهِ بْنِ دِينَارٍ عَنْ أَبِيهِ عَنْ أَبِي صَالِحٍ عَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيِّ ﷺ نَحْوَ هَذَا
