Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said:


إِنَّ اللَّهَ إِذَا أَحَبَّ عَبْدًا دَعَا جِبْرِيلَ فَقَالَ إِنِّي أُحِبُّ فُلَانًا فَأَحِبَّهُ قَالَ فَيُحِبُّهُ جِبْرِيلُ ثُمَّ يُنَادِي فِي السَّمَاءِ فَيَقُولُ إِنَّ اللَّهَ يُحِبُّ فُلَانًا فَأَحِبُّوهُ فَيُحِبُّهُ أَهْلُ السَّمَاءِ قَالَ ثُمَّ يُوضَعُ لَهُ الْقَبُولُ فِي الْأَرْضِ وَإِذَا أَبْغَضَ عَبْدًا دَعَا جِبْرِيلَ فَيَقُولُ إِنِّي أُبْغِضُ فُلَانًا فَأَبْغِضْهُ قَالَ فَيُبْغِضُهُ جِبْرِيلُ ثُمَّ يُنَادِي فِي أَهْلِ السَّمَاءِ إِنَّ اللَّهَ يُبْغِضُ فُلَانًا فَأَبْغِضُوهُ قَالَ فَيُبْغِضُونَهُ ثُمَّ تُوضَعُ لَهُ الْبَغْضَاءُ فِي الْأَرْضِ

When Allah loves a servant, He calls Gabriel and says: Verily, I love this person so you should love him. Then Gabriel loves him and makes an announcement in the heavens, saying: Allah loves this person and you should love him. Thus, the dwellers of the heavens love him and he is honored in the earth. When Allah is angry with a servant, He calls Gabriel and says: I have resentment for this person, so you should resent him. Then Gabriel is resentful towards him and makes an announcement in the heavens, saying: Verily, Allah is resentful with this person, so you should resent him. Thus, they become resentful with him and he is hated in the earth.
