In an attempt to understand a well-known though often unexamined exegetical principle,
this article offers a reading of the story of Joseph in light of two Quranic passages, namely 39:23
and, most importantly, 95:4-6. What links these texts is the concept of beauty. In 39:23, the
Quran is referred to as “the most beautiful discourse,” while 95:4 says that human beings were

the most beautiful of statures. ……………………..
