Narrated Abu Huraira:
The Prophet (ﷺ) said, "If Allah loves a person, He calls Gabriel saying: 'Allah loves so and so; O Gabriel, love him.' Gabriel would love him, and then Gabriel would make an announcement among the residents of the Heaven, 'Allah loves so-and-so, therefore, you should love him also.' So, all the residents of the Heavens would love him and then he is granted the pleasure of the people of the earth."
إِذَا أَحَبَّ اللَّهُ عَبْدًا نَادَى جِبْرِيلَ إِنَّ اللَّهَ يُحِبُّ فُلاَنًا، فَأَحِبَّهُ. فَيُحِبُّهُ جِبْرِيلُ، فَيُنَادِي جِبْرِيلُ فِي أَهْلِ السَّمَاءِ إِنَّ اللَّهَ يُحِبُّ فُلاَنًا، فَأَحِبُّوهُ. فَيُحِبُّهُ أَهْلُ السَّمَاءِ، ثُمَّ يُوضَعُ لَهُ الْقَبُولُ فِي أَهْلِ الأَرْضِ
