The answer of this question is, absolutely yes, not only Islam allows to do rape of infidel women, but also allows to buy and sell them, even use of protection (or some other measure so that woman does not become pregnant) Also forbidden while raping. Because for them, they are woman's of kafir's (infidel)
When believers attack on non-Muslims, or what they call jihad, if people accept Islam, they leave their way, then if anyone who do not accept this cult, they killed by them, now since the kafir (infidel) men's are dead, according to islam, these jihadis have the right over the land and property of those people? because this is the reward they got from their God in the return for jihad, but wait… let's say property is fine but what about the women and children of these infidels? So the answer is that, they are also mal-e-ganimat (war booty), and according to islam they should also be divide among themselves like the other property, I remember I was watching an interview of a Yazidi woman, who is In the arrest of ISIS, she says, "I was repeatedly given contraceptives and raped, because they were not allowed to do coitus interruptus (sexual intercourse in which the penis is withdrawn before ejaculation). and if I became pregnant, they couldn't do rape with me again and again. The work done by Muhammed is considered as Sunnah in Islam, in the easy language, sunnah is "virtue in Islam", That's why it is important to know, what did Muhammad do?
now Let us look at some Islamic sources...
Sahih al-Bukhari 2541
Narrated Ibn `Aun: I wrote a letter to Nafi` and Nafi` wrote in reply to my letter that the Prophet (ﷺ) had suddenly attacked Bani Mustaliq without warning while they were heedless and their cattle were being watered at the places of water. Their fighting men were killed and their women and children were taken as captives; the Prophet (ﷺ) got Juwairiya on that day. Nafi` said that Ibn `Umar had told him the above narration and that Ibn `Umar was in that army.
https://sunnah.com/bukhari:2541
This tells us two things, firstly, how brave the prophet was, and secondly, how the Islamic invaders were so successful even with a small army, because there were no moral rules of war for them. Islamic invaders in India were successful not because they were powerful, but because they were fighting against those people who believed in following moral rules of war.
Sahih Muslim Chapter 9
Chapter 9 : It is permissible to have intercourse with a female captive after it is established that she is not pregnant, and if she has a husband, then her marriage is annulled when she is captured
Sahih Muslim 1456 a
Abu Sa'id al-Khudri (Allah her pleased with him) reported that at the Battle of Hanain Allah's Messenger (ﷺ) sent an army to Autas and encountered the enemy and fought with them. Having overcome them and taken them captives, the Companions of Allah's Messenger (may peace te upon him) seemed to refrain from having intercourse with captive women because of their husbands being polytheists. Then Allah, Most High, sent down regarding that: " And women already married, except those whom your right hands possess (iv. 24)" (i. e. they were lawful for them when their 'Idda period came to an end).
https://sunnah.com/muslim:1456a
An interesting thing is that the people of that time also had at least such goodness that they refused to rape women whose husbands were alive. But Muhammad was so great that he makes an order on the name of allah that even "married women can be raped" That's why I believe "Islam can turns humans into animals"
Sahih al-Bukhari 2229
Narrated Abu Sa`id Al-Khudri: that while he was sitting with Allah's Messenger (ﷺ) he said, "O Allah's Messenger (ﷺ)! We get female captives as our share of booty, and we are interested in their prices, what is your opinion about coitus interrupt us?" The Prophet (ﷺ) said, "Do you really do that? It is better for you not to do it. No soul that which Allah has destined to exist, but will surely come into existence.
Chapter 109: The sale of slaves, Book 34: Sales and Trade
https://sunnah.com/bukhari:2229
coitus interruptus : sexual intercourse in which the penis is withdrawn before ejaculation
Sunan Abi Dawud 2172
Muhairiz said “I entered the mosque and saw Abu Sa’id Al Khudri . I sat with him and asked about withdrawing the penis (while having intercourse). Abu Sa’id said We went out with the Apostle of Allaah(ﷺ) on the expedition to Banu Al Mustaliq and took some Arab women captive and we desired the women for we were suffering from the absence of our wives and we wanted ransom, so we intended to withdraw the penis (while having intercourse with the slave women). But we asked ourselves “can we draw the penis when the Apostle of Allaah(ﷺ) is among us before asking him about it? So we asked him about it. He said “it does not matter if you do not do it, for very soul that is to be born up to the Day of Resurrection will be born.”
https://sunnah.com/abudawud:2172
Now the evil moves a step further, it is a matter to think that, there is not being discussed here about whether to rape or not, but it is being discussed whether to make them pregnant or not while raping them, is you remember the story of Yazidi woman which is mentioned above. as he told that they was not allowed to use protection while raping her, this act is based on these Sunnah.
Sunan Ibn Majah 2517
Jabir bin `Abdullah was heard to say: “We used to sell our slave women and the mothers of our children (Umahat Awaldina) when the Prophet (ﷺ) was still living among us, and we did not see anything wrong with that.”
Sahih al-Bukhari 947
Narrated Anas bin Malik: Allah's Messenger (ﷺ) (p.b.u.h) offered the Fajr prayer when it was still dark, then he rode and said, 'Allah Akbar! Khaibar is ruined. When we approach near to a nation, the most unfortunate is the morning of those who have been warned." The people came out into the streets saying, "Muhammad and his army." Allah's Messenger (ﷺ) vanquished them by force and their warriors were killed; the children and women were taken as captives. Safiya was taken by Dihya Al-Kalbi and later she belonged to Allah's Apostle go who married her and her Mahr was her manumission.
https://sunnah.com/bukhari:947
Safia is one from wives of prophate Muhammad, and you can see how she became his wife, Many Muslims claim that the Prophet married with widowed women, but it is interesting that, who widowed them? Mohammad killed Safiya's husband painfully, Juveria's husband was also killed by these people, Rihanna's entire tribe was wiped out and so many other painfull stories.
Now look at Some references from Quran
So consume what you have taken of war booty [as being] lawful and good, and fear Allāh. Indeed, Allāh is Forgiving and Merciful.

Quran 4:24
And [also prohibited to you are all] married women except those your right hands possess. [This is] the decree of Allāh upon you. And lawful to you are [all others] beyond these, [provided] that you seek them [in marriage] with [gifts from] your property, desiring chastity, not unlawful sexual intercourse. So for whatever you enjoy [of marriage] from them, give them their due compensation as an obligation. And there is no blame upon you for what you mutually agree to beyond the obligation. Indeed, Allāh is ever Knowing and Wise.
