Psalm 45

This was also one of the prophecies foretelling about Muhammad not Jesus(Peace be upon them), to prove this, we can look at the prophecy itself:
Psa 45:2 Thou art fairer than the children of men; Grace is poured into thy lips: Therefore God hath blessed thee for ever.
Muhammad (Peace be upon him) was very fair, Al-Bara' was asked, "Was the face of the Prophet (as bright) as a sword?" He said, "No, but (as bright) as a moon." (Bukhari), and Muhammad(Peace be upon him) was very rhetorical and this is very clear in his hadiths.
Psa 45:3 Gird thy sword upon thy thigh, O mighty one, Thy glory and thy majesty.
Muhammad (Peace be upon him) fought God's enemies, while Jesus (Peace be upon him) said:
Joh 18:11 Jesus therefore said unto Peter, Put up the sword into the sheath: the cup which the Father hath given me, shall I not drink it?
Some may refer this to his second coming, so let's continue on:
Psa 45:8 All thy garments smell of myrrh, and aloes, and cassia; Out of ivory palaces stringed instruments have made thee glad.
Muhammad (Peace be upon him) ruled and received gifts from Egyptian ruler, and from Heraclius, while Jesus (Peace be upon him) didn't rule.
Psa 45:9 Kings' daughters are among thy honorable women: At thy right hand doth stand the queen in gold of Ophir.
You believe that Jesus (Peace be upon him) didn't marry either kings' daughters or other women, but Muhammad (Peace be upon him) married 2 daughters of Arab leaders, and after his death, his descendent Al Hussein married the daughter of the last Persian king.
Psa 45:10 Hearken, O daughter, and consider, and incline thine ear; Forget also thine own people, and thy father's house: Psa 45:11 So will the king desire thy beauty; For he is thy lord; and reverence thou him.
This daughter is Safiyya daughter of Hoyay ibn Akhtab, this man was one of the Jewish leaders who fought Prophet Muhammad (Peace be upon him), and then Prophet Muhammad married her.
Saffiyah says, "I was my father's and my uncle's favorite child. When the Messenger of Allah came to Madinah and stayed at Quba, my parents went to him at night and when they looked disconcerted and worn out. I received them cheerfully but to my surprise no one of them turned to me. They were so grieved that they did not feel my presence. I heard my uncle, Abu Yasir, saying to my father, 'Is it really him (the final prophet) ?' He said, 'Yes, by Allah'. My uncle said: 'Can you recognize him and confirm this?' He said, 'Yes'. My uncle said, 'How do you feel towards him?' He said, 'By Allah I shall be his enemy as long as I live.'" (Ibn Hisham, As-Sirah an-Nabawiyyah)
Then the Prophet defeated Hoyayy in Khaibar's battle, and took Safiyya for himself, "at the beginning she used to hate him because he killed her father and husband, the Prophet kept on apologizing to her and telling:Your father charged the Arabs against me and committed heinous act," he apologized to the extent that made Safiyyah get rid of her bitterness against the Prophet" as mentioned by Al Bayhaqi in Dalael Al Nobowwa, And made her to choose if she would be free from captivation, or that she would marry him, and she chose to marry him as narrated by Ibn Hibban.
You may object saying that this Psalm tells about the Messiah, and give the script:
Psa 45:6 Thy throne, O God, is for ever and ever: A sceptre of equity is the sceptre of thy kingdom. Psa 45:7 Thou hast loved righteousness, and hated wickedness: Therefore God, thy God, hath anointed thee With the oil of gladness above thy fellows.
Well, when the Psalm says "O God", this is a praise for God, but then it came in verse 7, and retells about Muhammad (Peace be upon him), and it's very clear when it says "Therefore God, thy God hath anointed thee With the oil of gladness above thy fellows.", this clearly tells that the Messiah is not God, the word Messiah doesn't necessarily mean Jesus (Peace be upon him), but it means the annointed man as mentioned in 2Sa 1:14 concerning Saul.
2Sa 1:14 And David said unto him, How wast thou not afraid to put forth thy hand to destroy Jehovah's anointed?
This word for anointed is:
H4899
משׁיח mâshîyach maw-shee'-akh
From H4886; anointed; usually a consecrated person (as a king, priest, or saint); specifically the Messiah: - anointed, Messiah.
