﴿ وَعَلَّمَ ءَادَمَ ٱلْأَسْمَآءَ كُلَّهَا ثُمَّ عَرَضَهُمْ عَلَى ٱلْمَلَٰٓئِكَةِ فَقَالَ أَنۢبِـُٔونِى بِأَسْمَآءِ هَٰٓؤُلَآءِ إِن كُنتُمْ صَٰدِقِينَ ﴾

“And He imparted unto Adam the names of all things; then He brought them within the ken of the angels and said: "Declare unto Me the names of these [things], if what you say is true."”

The mixture of good and evil in mankind became evident when God, in His omnipotence, brought all the progeny of Adam before their first father. He said to the angels, ‘Look, these are the progeny of Adam. Can you give me the name of each one of them, and say what sort of people they will be?’ The angels, having no knowledge of them, were unable to answer. Then God told Adam their names and characteristics, and then commanded him to pass the knowledge on to the angels. When Adam had explained to them the nature of the human race, they realized that, besides the wicked and the corrupt, there would also be among their number great, righteous and pious souls.
