Mukhtasar Bukhari

Narrated Abu Huraira (may Allah be pleased with him) from the Prophet (peace and blessings of Allah be upon him) that he said: "When Allah loves a servant, He calls Jibreel (peace be upon him) and says: 'Allah loves so-and-so, so you should also love him.' So Jibreel (peace be upon him) begins to love him. Then Jibreel (peace be upon him) announces among the inhabitants of the heavens that Allah loves so-and-so, so you should also love him. Thus, all the inhabitants of the heavens begin to love him, and then acceptance for him is placed among the people of the earth."
