Narrated Anas:
Allah’s Messenger SALALLAHU ALAIHI WASALAM said,

“Whoever possesses the (following) three qualities will have the sweetness of faith

(1): The one to whom Allah and His Apostle becomes dearer than anything else;

(2) Who loves a person and he loves him only for Allah’s Sake;

(3) who hates to revert to atheism (disbelief) as he hates to be thrown into the Fire
