Narrated Anas:

The Prophet (ﷺ) said, "Whoever possesses the following three qualities will have the sweetness (delight) 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 be thrown into the fire."
