Reported by Jundub (RA): The Prophet (peace be upon him) said, “He who lets the people hear of his good deeds intentionally, to win their praise, Allah will let the people know his real intention (on the Day of Resurrection), and he who does good things in public to show off and win the praise of the people, Allah will disclose his real intention (and humiliate him).”
Reported by Abu Hurairah (RA): The Prophet (peace be upon him) said, “When Allah loves a slave, calls out Jibril and says: `I love so-and-so; so love him’. Then Jibril loves him. After that he (Jibril) announces to the inhabitants of heavens that Allah loves so-and-so; so love him; and the inhabitants of the heavens (the angels) also love him and then make people on earth love him”.
[Bukhari & Muslim]
Reported by Abu Hurairah (RA): The Messenger of Allah (peace be upon him) said: “Verily, Allah will say on the Day of Resurrection: ‘Where are those who love each other for my Glory’s sake? Today I shall shelter them in My Shadow when there is no shadow other than Mine.”
