Did God declare/make your religion (Christianity/Judaism) perfect. Does the names of "Christianity" and "Judaism" have divine inspiration. Can you show me a single verse to that effect? NO

BUT GOD DECLARED ISLAAM THE PERFECT RELIGION:

Noble Qur’aan 5:3! … This day, I have perfected your religion for you, completed My Favour upon you, and have chosen for you Islâam as your religion…

Did God promise to guard your bible from corruption, can you show me a single verse to this effect? NO

BUT GOD PROMISED AND HAS BEEN PROTECTING NOBLE QURAN:

Noble Quran 15:9! Verily We: It is We Who have sent down the Dhikr (i.e. the Qur'ân) and surely, We will guard it (from corruption)[].

Did God say the religion of God is Christianity/Judaism, can you show me a single verse to this effect? NO

BUT GOD DECLARED THE RELIGION OF GOD (ALLAH) IS ISLAAM:

Noble Quran 3:19! Truly, the religion with Allâh is Islâam. Those who were given the Scripture (Jews and Christians) did not differ except, out of mutual jealousy, after knowledge had come to them. And whoever disbelieves in the Ayât (proofs, evidences, verses, signs, revelations, etc.) of Allâh, then surely, Allâh is Swift in calling to account.

Noble Quran 5:3! … This day, I have perfected your religion for you, completed My Favour upon you, and have chosen for you Islâam as your religion…

Does the name(s) "Christian/Jew" have divine inspiration? NO

BUT NAME "MUSLIM" HAS DIVINE INSPIRATION:

Noble Quran 3:64! Say (O Muhammad SAW): "O people of the Scripture (Jews and Christians): Come to a word that is just between us and you, that we worship none but Allâh, and that we associate no partners with Him, and that none of us shall take others as lords besides Allâh[]. Then, if they turn away, say: "Bear witness that we are "Muslims."

That is why Islaam is a perfect religion and Christianity/Judaism NOT.

That is why Noble Quraan is a perfect book guarded and protected by God Almighty Himself since its revelation. Contrary to that bible (OT&NT) are corrupted and adulterated.

Islaam has abrogated all religions:

Noble Quran 3:85! "And whoever seeks a religion other than Islam, it will never be accepted of him, and in the hereafter he will be one of the losers." [Al-Qur'an 3:85]

There is no disagreement among the Islamic scholars concerning the abrogation of previous religions like Judaism and Christian and that believing in their validity is a form of kufr.

Muhammad Ibn al-Alâ' told us that Ibn Numayr reported from Mujâlid from Ibn Aamir from Jâbir that Umar Ibn al-Khattâb brought a copy of the Torah to the Prophet (P) and said: "O Apostle of God, this is a copy of the Torah." But [the Prophet] kept silent. Then Umar started reading and the face of the Prophet kept changing. So, Abu Bakr interrupted him violently: "Don't you see the face of the Prophet (P)?" Umar looked at the Prophet's face and said "May God preserve me from His anger and from the anger of his Apostle (P), we accepted God as Lord and Islâm as religion and Muhammad as prophet." Then the Prophet (Pbuh) said: "By the One Who owns Mohammed’s soul, if Moses (Pbuh) appeared to you and you followed him and left me, you would go astray from the right path and if he were alive and reached [the time of] my Prophethood he would have followed me.
