It was narrated that Qatadah said:"I heard Anas bin Malik narrating that the Prophet [SAW] said: 'There are three things, whoever attains them will find therein a sweetness of faith: When he loves a person, and only loves him for the sake of Allah [SWT]; when Allah [SWT] and His Messenger [SAW] are dearer to him than all else; and when he would prefer to be thrown into the fire rather to go back to the disbelief from which Allah [SWT] has saved him
