These are but names that you made up, you and your forefathers. GOD never authorized such a blasphemy. They follow conjecture, and personal desire, when the true guidance has come to them herein from their Lord. The only ones permitted by GOD are those who act in accordance with His will and His approval. Those who disbelieve in the Hereafter have given the angels feminine names.
Conjecture is no substitute for the truth.
You shall disregard those who turn away from our message, and become preoccupied with this worldly life. This is the extent of their knowledge. Your Lord is fully aware of those who strayed away from His path, and He is fully aware of those who are guided. To GOD belongs everything in the heavens and everything on earth. He will requite those who commit evil for their works, and will reward the righteous for their righteousness.
