He is using taqqiya. The Quran does not condone rape OF MUSLIM WOMEN.
However, INFIDEL women, especially infidel women who are under the power of Muslims, are another story.
And if you fear that you will not deal justly with the orphan girls, then marry those that please you of [other] women, two or three or four. But if you fear that you will not be just, then [marry only] one or those your right hand possesses. That is more suitable that you may not incline [to injustice]."Those your right hand possesses" = Slave girls, captured infidel women.
O Prophet! surely We have made lawful to you your wives whom you have given their dowries, and those whom your right hand possesses out of those whom Allah has given to you as prisoners of war, and the daughters of your paternal uncles and the daughters of your paternal aunts, and the daughters of your maternal uncles and the daughters of your maternal aunts who fled with you; and a believing woman if she gave herself to the Prophet, if the Prophet desired to marry her-- specially for you, not for the (rest of) believers; We know what We have ordained for them concerning their wives and those whom their right hands possess in order that no blame may attach to you; and Allah is Forgiving, Merciful.The above also explains why there's so much inbreeding in Muslim societies. If you want to marry a non-related Muslim girl, the husband must pay a dowry to her (actually to her family). If he marries a cousin on his father's side, no dowry is needed.
“That is more suitable that you may not incline [to injustice]. “
Not inclining to injustice is the qualifier - rape is injustice. Therefore you could say that verse does not justify rape or any other kind of injustice with infidel women.
“And if you fear that you will not deal justly with the orphan girls, then marry those that please you of [other] women, two or three or four. But if you fear that you will not be just, then [marry only] one or those your right hand possesses. That is more suitable that you may not incline [to injustice]. “
If you read that accurately the reason for marrying the orphan girls is “if you fear will not deal justly” with them. The point seems to be; do not deal unjustly with them, which would include not raping them. Rape is injustice by any standard.
Maybe there are other verses that clearly and accurately justify raping infidel women but that one doesn’t.
