Assalmoelaikoem warhamatullahi wbarakatoh dear brothers and sister,
Welcome Lychee, May Allah open your heart to revert soon. I ask Allah subhanahu wata3ala to increase your knowledge about islam.
and to my dear brother Tahar you have to know that there are big differences between the old and new testament and the Quraan. The tawra is send to moesa ( mozes) and the indjiel ( bible) to Isa ( jesus) from our Lord, but now they are not the original. Some statements are deleted and changed.
Allah says: "
Then woe to those who write the Book with their own hands and then say, "This is from Allah", to purchase with it a little price! Woe to them for what their hands have written and woe to them for that they earn thereby.}" [2:79]
The Quraan will never change, because Allah subhanahu wata3ala is The One who will keep it reserved, the Quraan will never altered.
Allah says: "
Verily, We, it is We, Who have Sent down the Dhikr (i.e. the Qur'an) and surely, We will guard it (from corruption)."[15: 9]

They said Allah has a son. Allah subhanahu wata3ala don't have a son. Isa ( Jesus) is only a messenger from Allah and a human being.
Allah says:
{And there is none of the people of the Scripture (Jews and Christians), but must believe in him ['Isa (Jesus), son of Maryam (Mary), as only a Messenger of Allâh and a human being], before his ['Isa (Jesus) or a Jew's or a Christian's] death (at the time of the appearance of the angel of death). And on the Day of Resurrection, he ['Isa (Jesus)] will be a witness against them.} [4:159].
Allah says also:
"And Allah will teach him the Book and Wisdom, The Torah and the Gospel., And appoint him A Messenger to the children of Israel ..etc.} [3:48].
They say trinity and Allah says: " Don't say trinity"
Allah says: "
{Surely, disbelievers are those who said: "Allah is the third of the three (in a Trinity)". But there is no Ilah (god) (none who has the right to be worshipped) but One Ilah (God-Allah). …..} [5:73]
Some of them say Isa ( jesus) is God. Allah denied this. He says:
{Surely, they have disbelieved who say: "Allah is the Messiah [Isa (Jesus)], son of Maryam (Mary)". …} [5:72]
Dear brother this are big differences. This are differences in Tawheed, so big differences.
If i have made a mistake, please correct me.
