The Book of Virtue, Good Manners and Joining of the Ties of Relationship (Kitab Al-Birr was-Salat-I-wa'l-Adab)
Muslim :: Book 32 : Hadith 6373
Abu Huraira reported that Allah's Messenger (may peace be upon him) said: When Allah loves a servant, He calls Gabriel and says: Verily, I so and so; you should also love him, and then Gabriel begins to love him. Then he makes an announcement in the heaven saying: Allah loves so and so and you also love him, and then the inhabitants of the Heaven (the Angels) also begin to love him and then there is conferred honour upon him in the earth; and when Allah is angry with any servant He calls Gabriel and says: I am angry with such and such and you also become angry with him, and then Gabriel also becomes angry and then makes an announcement amongst the inhabitants of heaven: Verily Allah is angry with so-and so, so you also become angry with him, and thus they also become angry with him. Then he becomes the object of wrath on the earth also.
