Lit., "self-evident (bayyinat) in the breasts of those who have been given knowledge" - the term 'ilm having here the connotation of intuitive, spiritual perception.
Cf. the last clause of verse 47 above. There the argument was that the rejection of the Qur-an was a mark of Unbelief. Now the argument is carried a stage farther. Such rejection is also a mark of injustice, a deliberate perversity in going against obvious Signs, which should convince all honest men.
"Knowledge" ('ilm) means both power of judgment in discerning the value of truth and acquaintance with previous revelations. It implies both literal and spiritual insight. To men so endowed, Allah's revelations and Signs are self-evident. They commend themselves to their hearts, minds, and understandings, which are typified in Arabic by the word sadr, "breast".
