Who Was the First Kafir?

S 2:34 And when we said to the angels: Do sujud to Adam, they did sujud except Iblis. He refused and was arrogant and was of the kafirun.

We are told that Iblis was of the kafirun (kuffar). But this is immediately after Adam's creation. Iblis was apparently not the first kafir and certainly not the only kafir at the time.

In the following verse, are we to understand that there were 'wrongdoers' in existence at the time?

And we said: Adam, dwell, you and your husband, in the Jannah and eat of it carefree where you have willed. But do not approach this tree so you be of the wrongdoers.

Wife or Husband?

Compare S 2:34 with S 6:14.

Say: Is it other than Allah that I should take as a protector, the splitter of the skies and the Earth, and he feeds and is not fed? Say: I have been commanded to be the first of those who have surrendered and you are not to be of the mushrikun.

Iblis was of the kafirun; Allah's boss was not to be of the mushrikun. It will not be argued that the latter was not to be of the mushrikun who might be around in the future; they were (supposedly) around then.

S 7:11 And we created you then we formed you. Then we said to the angels: Do sujud to Adam. So they did sujud except Iblis. He was not of those who did sujud.

Iblis was of the kafirun; he was not of those who did sujud. Would 'those who did sujud', namely the angels, refer to those in the future, or would they have been present at the time?

The Angels Commanded to Do Sujud and Iblis’ Refusal
