Why Lol?
I am not sure how the two are connected but yes its a ashamed that groups like the Nation of Islam follow Shirk and that people like like Malcolm X had to die because he left the Shirk group.
Hadith ''Qudsi'' is not Authentic and the Quran does verify that but it never says that these previous revelations are still intact, if that was the case there would be no need for Islam (The Quran). Duh?
You quoted Al-Bagarah but if it you read it in context it later says:
Can ye (o ye men of Faith) entertain the hope that they will believe in you?- Seeing that a party of them heard the Word of Allah, and perverted it knowingly after they understood it
Then woe to those who write the Book with their own hands, and then say:"This is from Allah," to traffic with it for miserable price!- Woe to them for what their hands do write, and for the gain they make thereby. (Quran 2:75,79)
and here are more:
There is among them a section who distort the Book with their tongues: (As they read) you would think it is a part of the Book, but it is no part of the Book; and they say, "That is from Allah," but it is not from Allah: It is they who tell a lie against Allah, and (well) they know it! (Quran 3:78)
And remember Allah took a covenant from the People of the Book, to make it known and clear to mankind, and not to hide it; but they threw it away behind their backs, and purchased with it some miserable gain! And vile was the bargain they made! (Quran 3:187)
But because of their breach of their covenant, We cursed them, and made their hearts grow hard; they change the words from their (right) places and forget a good part of the message that was sent them, nor wilt thou cease to find them- barring a few - ever bent on (new) deceits: but forgive them, and overlook (their misdeeds): for Allah loveth those who are kind. From those, too, who call themselves Christians, We did take a covenant, but they forgot a good part of the message that was sent them: so we estranged them, with enmity and hatred between the one and the other, to the day of judgment. And soon will Allah show them what it is they have done. (Quran 5:13-14)
No just estimate of Allah do they make when they say: "Nothing doth Allah send down to man (by way of revelation)" Say: "Who then sent down the Book which Moses brought?- a light and guidance to man: But ye make it into (separate) sheets for show, while ye conceal much (of its contents): therein were ye taught that which ye knew not- neither ye nor your fathers." Say: "Allah (sent it down)": Then leave them to plunge in vain discourse and trifling. (Quran 6:91)
And there are many more now lets go to Authentic Hadiths:
Narrated Abu Huraira: The people of the Scripture (Jews) used to recite the Torah in Hebrew and they used to explain it in Arabic to the Muslims. On that Allah's Apostle said, "Do not believe the people of the Scripture or disbelieve them, but say:-- "We believe in Allah and what is revealed to us." (2.136) (Bukhari Volume 6, Book 60, Number 12)
Narrated Ubaidullah: Ibn 'Abbas said, "Why do you ask the people of the scripture about anything while your Book (Quran) which has been revealed to Allah's Apostle is newer and the latest? You read it pure, undistorted and unchanged, and Allah has told you that the people of the scripture (Jews and Christians) changed their scripture and distorted it, and wrote the scripture with their own hands and said, 'It is from Allah,' to sell it for a little gain. Does not the knowledge which has come to you prevent you from asking them about anything? No, by Allah, we have never seen any man from them asking you regarding what has been revealed to you!" (Bukhari Volume 9, Book 92, Number 461)
Narrated 'Ubaidullah bin 'Abdullah: 'Abdullah bin 'Abbas said, "O the group of Muslims! How can you ask the people of the Scriptures about anything while your Book which Allah has revealed to your Prophet contains the most recent news from Allah and is pure and not distorted? Allah has told you that the people of the Scriptures have changed some of Allah's Books and distorted it and wrote something with their own hands and said, 'This is from Allah, so as to have a minor gain for it. Won't the knowledge that has come to you stop you from asking them? No, by Allah, we have never seen a man from them asking you about that (the Book Al-Qur'an ) which has been revealed to you. (Bukhari Volume 9, Book 93, Number 614)
Now i can keep on continuing but you get the idea, Islam clearly teaches that the ''Bible'' has been changed/corrupted and forgotten.
Even Christian biblical scholars and Historians agree that the bible has been edited in time why can't you?
Salaam.
