5111. It was narrated that Abū Hurairah said: "Some of his Companions came to him and said: 'O Messenger of Allāh, we find something in our hearts that is so awful that we cannot speak of it, and we would not like to speak of it no matter what we may be given in return.' He said: 'Do you really experience that?' They said: 'Yes.' He said: 'That is clear faith.'"[1] (Sahih)
