We are all slaves of Allah, but what if he decided to free someone very noble who asked to be freed? What would happen to that person, if he decided not to continue to serve Allah as his servant? What if he continued to serve Allah as a servant?
If Mohammad (PBUH) asked to be freed, would Allah accept his wish?
Also, is Iblis free? He does not fit the definition of noble, so its a different question than the first one.
This is an opinion based question, but please support your opinion with evidence from the Quran and Hadith. And I know that it is unlikely anyone will ever ask Allah to free them due to gratitude towards Allah.
