49 Preface بَل هُوَ آياتٌ بَيِّناتٌ في صُدورِ الَّذينَ أوتُوا العِلمَ ۚ وَما يَجحَدُ بِآياتِنا إِلَّا الظّالِمونَYusuf AliNay, here are Signs self-evident in the hearts of those endowed with knowledge:1 and none but the unjust reject Our Signs.2“Knowledge” ('ilm) means both power of judgment in discerning the value of truth and acquaintance with previous revelations. It implies both literary and spiritual insight. To men so endowed, God’s revelations and Signs are selfevident. They commend themselves to their hearts, minds, and understandings, which are typified in Arabic by the word sadr, “breast”.Cf. the last clause of verse 47 above. There the argument was that the rejection of the Qur-ān 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.
