Lol. Yes, Arabs enslaved people but it was nowhere close to the brutality which was the Transatlantic Slave Trade. And let's not forget it being the largest procurement of slaves with millions of death according to historians and academics. It was such a large and brutal slave trade that the effects of it can still be felt today.
Also, slavery existed prior to Islam and was being done by all people's around the world. It was more done for economic reasons and slavery wasn't specific to a certain race. When Christians got tired of enslaving their own people they decided to enslave black people because they literally thought they were better than them. With Bibles within their hands they set off and participated in the most brutal and largest slave trade the world would ever know.
Also, you talk about conquests but you forget to mention that the Persians and Christian Roman empire started the game first but then when they started losing you cry foul now. Keep quiet hypocrite.
Hopefully everyone reading this can pick up on the fact that you've provided no links and PROOF for your claims. I will though.
First, lets see what your scriptures say about this:
From:
https://www.answering-islam.org/Silas/slavery.htm
33:50 - "Prophet, We have made lawful to you the wives to whom you have granted dowries and the slave girls whom God has given you as booty."
23:5 - "... except with their wives and slave girls, for these are lawful to them:..."
The Quran also instructs Muslims NOT to force their female slaves into prostitution (24:34), and even allows Muslims to marry slaves if they so desire (4:24), and to free them at times as a penalty for crime or sin (4:92, 5:89, 58:3) and even allows slaves to buy their liberty, if they meet certain of their master's conditions (24:33). [90:10 'freeing of a bondsman' refers to Muslims ransoming other Muslims who were slaves of non-Muslims.]
Hadiths:
Sahih Bukhari:
Vol. 5-#459 [This Hadith is similar to the above. However, additional details are added]. Narrated Ibn Muhairiz: "I entered the mosque and saw Abu Khudri and sat beside him and asked him about coitus interruptus. Abu said, "We went out with Allah's messenger for the Ghazwa (attack upon) Banu Mustaliq and we received captives from among the Arab captives and we desired women and celibacy became hard on us and we loved to do coitus interruptus. So when we intended to do coitus interruptus we said "How can we do coitus interruptus without asking Allah's messenger while he is present among us?" We asked (him) about it and he said "It is better for you not to do so, for if any soul (till the Day of Resurrection) is predestined to exist, it will exist.""
Vol. 3-#765
Narrated Kuraib: the freed slave of Ibn 'Abbas, that Maimuna bint Al-Harith told him that she manumitted a slave-girl without taking the permission of the Prophet. On the day when it was her turn to be with the Prophet, she said, "Do you know, O Allah's Apostle, that I have manumitted my slave-girl?" He said, "Have you really?" She replied in the affirmative. He said, "You would have got more reward if you had given her (i.e. the slave-girl) to one of your maternal uncles."
- Mohammad discourages her freeing slave
Vol. 5-#637 Narrated Buraida: The prophet sent Ali to Khalid to bring the Khumus ([one fifth] of the booty) and I hated Ali, and Ali had taken a bath (after a sexual act with a slave girl from the Khumus). I said to Khalid, "Don't you see this (i.e. Ali)?" When we reached the prophet I mentioned that to him. He said, "O Buraida! Do you hate Ali?" I said, "Yes" He said, "Do you hate him, for he deserves more than that from the Khumus."
The note for this Hadith says "Buraida hated Ali because he had taken a slave girl form the booty and considered that as something not good."
Vol. 7-#734 "....At the door of the [Muhammad's] room there was a slave to whom I went and said, "Ask the permission for me to enter".....
- Mohammad owned slaves
Abu Dawud, vol. 2, chapter 597 - "On a Man who Beats His Slave While he is in the Sacred State (wearing Ihram)."
#1814- "(Abu Bakr) began to beat him (Bakr's slave) while the apostle of Allah was smiling and saying: "Look at this man who is in the sacred state, what is he doing?" [The note for this Hadith says "Abu Bakr beat his slave to teach him sense of responsibility."]
Islamic scriptures clearly endorsed enslavement, r*pe of slave girls, and even discouraged freeing slaves (going off that one Hadith).
The Old Testament also endorsed slavery, in a relatively similar way to the Quran/Hadiths.
There were some minor differences:
Exodus 21:26-27
“When a man strikes the eye of his slave, male or female, and destroys it, he shall let the slave go free because of his eye. If he knocks out the tooth of his slave, male or female, he shall let the slave go free because of his tooth.
Deuteronomy 21:10-14
“When you go out to war against your enemies, and the Lord your God gives them into your hand and you take them captive, and you see among the captives a beautiful woman, and you desire to take her to be your wife, and you bring her home to your house, she shall shave her head and pare her nails. And she shall take off the clothes in which she was captured and shall remain in your house and lament her father and her mother a full month. After that you may go in to her and be her husband, and she shall be your wife. But if you no longer delight in her, you shall let her go where she wants. But you shall not sell her for money, nor shall you treat her as a slave, since you have humiliated her.
Leviticus 19:33-34
“When a stranger sojourns with you in your land, you shall not do him wrong. You shall treat the stranger who sojourns with you as the native among you, and you shall love him as yourself, for you were strangers in the land of Egypt: I am the Lord your God.
Deuteronomy 23:15
Do not return a slave to his master if he has taken refuge with you. 16Let him live among you wherever he chooses, in the town of his pleasing. Do not oppress him
However, the New Testament, in the Gospels, abrogated some of the Mosaic law, ie: love your enemy (as opposed to hate them), more emphasis on forgiveness. The Golden rule, and some more emphasis on charity. Putting this together, we have concrete evidence that Christianity is more anti-Slavery and pro humane treatment compared to Islam.
Historical evidence:
en.wikipedia.org
" while other estimates indicate a number between 12 and 15 million slaves prior to the 20th century.
[7]"
en.wikipedia.org
Current estimates are that about 12 million to 12.8 million Africans were shipped across the Atlantic over a span of 400 years,
[6][7]:194 although the number purchased by the traders was considerably higher, as the passage had a high death rate with approximately 1.2–2.4 million dying during the voyage and millions more died in seasoning camps in the Caribbean after arrival to the New World.
So it seems like they had similar amounts of slaves, perhaps the Transatlantic had more.
As for the treatment of slaves, that would take a lot of research, not gonna bother.
Either way, Im gonna reemphasize the fact that the increase of slavery happened well after the advent of Christianity. Slavery was already institionalized with the Roman Empire but the adoption of Christianity (albeit a paganized one) led to reforms occurring that slowed down slavery. This was the exact opposite with the Muslim slave trade.
