It was narrated from Anas that :The Prophet [SAW] said: "There are three things, whoever attains them will find therein the sweetness of Islam: When Allah [SWT] and His Messenger [SAW] are dearer to him than all else; when he loves a person and only loves him for the sake of Allah [SWT]; and when he would hate to go back to disbelief as much as he would hate to be thrown into the fire
