Reference for that one? Muhammad (saw) had excellent relationships with many Jewish tribes of Medina:
[Qur'an 60:9] "Allah forbids you not, respecting those who have not fought against you on account of your religion, and who have not driven you forth from your homes, that you be kind to them and act equitably towards them; surely Allah loves those who are equitable."
I believe we should be able to quote our primary scripture to show our claims. But the salvation you mention ... can you even quote Jesus' god-hood from your scripture? Or Trinity for that matter?
Jesus's Godhood (Philippians 2):
5 Have this mind among yourselves, which is yours in
Christ Jesus, 6 who, though he was in the form of God, did not count equality with God a thing to be grasped, 7
but emptied himself, by taking the form of a servant, being born in the likeness of men. 8 And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross. 9 Therefore God has highly exalted him and bestowed on him the name that is above every name, 10 so that
at the name of Jesus every knee should bow, in heaven and on earth and under the earth, 11 and
every tongue confess that Jesus Christ is Lord, to the glory of God the Father.
Tri-unity of God (1 John 5:7):
For there are three that bear record in Heaven:
the Father, the Word, and the Holy Spirit; and
these three are one.

Different versions concerning the sentence of Sa‘d b. Mu‘adh[edit]
I) Secondary Sources
- Norman A. STILLMAN, in his book “The Jews of Arab Lands: A History and Source Book”, page 141 said :
When Sa‘d reached the Apostle of Allah-may Allah bless him and grant him peace-the Apostle said, “Rise to greet your leader.” The emigrants of Quraysh said to themselves that the Apostle must be referring to the Helpers. The helpers, on the other hand, thought the Apostle was including everyone, and so they got up and said, “O Abu ‘Amr, the Apostle has appointed you arbiter the fate of your clients so that you may pass judgment upon them.”
“Will you accept as binding, by Allah’s covenant and His Pact, the judgment upon them once I have given it?” They replied that they would. “And will it be binding upon one who is here,” he said turning toward the Apostle, not mentioning him by name out of respect. The Apostle of Allah-may Allah bless him and grant him peace-answered yes. Sa‘d said, “My judgment is that that the men be executed, their property divided, and the women and children made captives. ‘Asim b. ‘Umar b. Qatada told me on the authority of ‘Abd al-Rahman b. ‘Amr b. Sa‘d b. Mu‘adh on the authority of Alqama b. Waqqas al-Laythi that the Apostle said to Sa‘d, “You have judged them according to the verdict of Allah above the seventh heaven."
- Martin LINGS (British converted to Islam), in his book "MUHAMMAD: his life based on the earliest sources", page 231 and 232 said :
Sa‘d was a man of mighty stature, of handsome and majestic appearance, and when he came to the camp the Prophet said "Rise in honour of your liege lord," and they rose to greet him saying: "Father of ‘Amr, the Messenger of God hath appointed thee to judge the case of thy confederates." He said: "Do ye then swear by God and make by Him your covenant that my judgement shall be the verdict upon them?" "We do," they answered. "And is it binding upon him who is here?" he added, with a glance in the direction of the Prophet, but not mentioning him out of reverence. "It is," said the Prophet. "Then I judge," said Sa‘d, "that the men shall be slain, the property divided, and the women and children made captive."1 The Prophet said to him: "Thou hast judged with the judgement of God from above the seven heavens."
Martin LINGS added the footnote 1 at the bottom of the page 232
1 Sa‘d's judgment was no doubt directed mainly against their treachery; but in fact it coincided exactly with Jewish law as regards the treatment of a besieged city, even if it were innocent of treachery: When the Lord thy God hath delivered it unto thy hands, thou shalt smite every male therein with the edge of the sword: but the women, and the little ones, and the cattle, and all that is in the city, even all the spoil thereof, shalt thou take unto thyself. Deuteronomy 20: 12.
- Daniel C. Peterson, in his book “Muhammad, Prophet of God”, page 127, said :
After receiving promises from all the Muslims present that they would indeed abide by his judgment, Sa‘d decreed the execution of the men of Banu Qurayza, the enslaving of their women and children, and the division of their property among the muslims.5 “You have judged,” said the Prophet, “with the judgment of God from above the seven heavens.”6
Daniel C. Peterson added the footnote 6 at the bottom of the page 127
6. PERHAPS with some apologetic intent, the late English scholar Martin Lings notes, correctly, that Sa'd judgment accords with that of the law of Moses as recorded in Deut. 20:10:14. See Lings, p. 232 n.1.
II) Primary Source (Ishaq’s Sirat Rasul Allah is the oldest and most complete biography of Muhammad)
A. GUILLAUME, in his book “The life of Muhammad: A translation of Ishaq’s Sirat Rasul Allah”, page 463, 464 said:
When Sa‘d reached the apostle and the Muslims the apostle told them to get up to greet their leader. The muhajirs of Quraysh thought that the apostle meant the Ansar. while the latter thought that he meant everyone, so they got up and said ‘O Abu ‘Amr, the apostle has entrusted to you the affair of your allies that you may give judgment concerning them.’ Sa‘d asked, ‘Do you covenant by Allah that you accept the judgment I pronounce on them?’ They said Yes, and he said ‘And is it incumbent on the one who is here?’ (looking) in the direction of the apostle, not mentioning him out of respect, and the apostle answered Yes. Sa‘d said, ‘Then I give judgment that that the men should be killed, their property divided, and the women and children taken as captives.
‘Asim b. ‘Umar b. Qatada told me on the authority of ‘Abdul-Rahman b. ‘Amr b. Sa‘d b. Mu‘adh from Alqama b. Waqqas al-Laythi that the apostle said to Sa‘d, ‘You have given the judgement of Allah above the seven heavens.’
