Muhammad - Prophet Isa (Jesus) is telling his followers about the coming of Prophet Muhammad as the final messenger, according to the Quran

Quran emphasizes the importance of worshipping Allah alone and declaring that Allah is the Lord of all humanity. The verse also emphasizes that worshipping Allah is the straight path or the right way, highlighting the importance of monotheism and submitting to Allah's will.

Quran 3:51 is:

"إِنَّ اللَّهَ رَبِّي وَرَبُّكُمْ فَاعْبُدُوهُ ۚ هَٰذَا صِرَاطٌ مُّسْتَقِيمٌ"

The translation of the verse is:

"Indeed Allah is my Lord and your Lord, so worship Him. This is the straight path."

This verse is part of a larger passage in Surah Al-Imran where Prophet Isa (Jesus) is telling his followers about the coming of Prophet Muhammad as the final messenger. The verse emphasizes the fact that Allah is the Lord of Prophet Isa as well as all humanity and urges people to worship Him alone. The verse also declares that worshipping Allah is the straight path or the right way, highlighting the importance of monotheism and submitting to Allah's will.

There is a passage in the Quran (Surah Al-Imran, 3:81) that mentions a covenant that Allah took from the prophets, including Prophet Isa (Jesus), to believe in and support the final messenger, Prophet Muhammad:

"And when Allah took the covenant of the prophets, [saying], "Whatever I give you of the Scripture and wisdom and then there comes to you a messenger confirming what is with you, you [must] believe in him and support him." [Allah] said, "Have you acknowledged and taken upon that My commitment?" They said, "We have acknowledged it." He said, "Then bear witness, and I am with you among the witnesses."

While this passage does not explicitly mention Prophet Jesus saying that Prophet Muhammad is the final messenger, it is believed to refer to him as one of the prophets who was instructed to support the final messenger. The belief that Prophet Muhammad is the final messenger of Allah is a fundamental principle of Islam.

In addition to the above-mentioned verse, there are several other verses in the Quran that affirm the finality of the prophethood of Prophet Muhammad. For example:

Surah Al-Ahzab 33:40 states: "Muhammad is not the father of [any] one of your men, but [he is] the Messenger of Allah and the last of the prophets. And ever is Allah, of all things, Knowing."

Surah Al-Ma'ida 5:3 states: "This day I have perfected for you your religion and completed My favor upon you and have approved for you Islam as religion."

Surah Al-An'am 6:115 states: "And the word of your Lord has been fulfilled in truth and in justice. None can alter His words, and He is the Hearing, the Knowing."

These verses, along with others in the Quran, affirm that Prophet Muhammad is the final messenger of Allah and that his message is complete and perfect.
