Sayyiduna Abu Umamah (may Allah be pleased with him) says: The Messenger of Allah (peace and blessings be upon him) said: "Love is from Allah, and renown is decreed in the heavens. When Allah loves a servant, He says: 'O Jibril, your Lord loves so-and-so, so love him too.' So Jibril announces in the heavens: 'Your Lord loves so-and-so, so love him too.' Then love for him is placed in the hearts of the people of the earth."
