It’s a fact that prophet’s Mohamed’s tomb is not empty because prophet’s bodies don’t decompose (he died and his body is still there and this is a proof that he is a prophet). While there is no body for prophet Jesus peace be upon him and in the Quran he wasn’t crucified, he didn’t die and he’ll return and Muslim people will follow his lead as a prophet without pending knees because that is done to God only and Jesus peace be upon him will pray with us to Allah (they couldn’t justify not having the body so they made up a story).
If you believe in the Quran or not it’s not my concern as it’s for yourself or on it to find guidance.
39:41 Az-Zumar
إِنَّا أَنْزَلْنَا عَلَيْكَ الْكِتَابَ لِلنَّاسِ بِالْحَقِّ ۖ فَمَنِ اهْتَدَىٰ فَلِنَفْسِهِ ۖ وَمَنْ ضَلَّ فَإِنَّمَا يَضِلُّ عَلَيْهَا ۖ وَمَا أَنْتَ عَلَيْهِمْ بِوَكِيلٍ
Indeed, We sent down to you the Book for the people in truth. So whoever is guided - it is for [the benefit of] his soul; and whoever goes astray only goes astray to its detriment. And you are not a manager over them.
However, the Quran is delivered to prophet Mohamed peace be upon him and protected by God so that it wasn’t changed since the very first copy (on the contrary the Bible and Torah were modified).
15:9 Al-Hijr
إِنَّا نَحْنُ نَزَّلْنَا الذِّكْرَ وَإِنَّا لَهُ لَحَافِظُونَ
Indeed, it is We who sent down the Qur'an and indeed, We will be its guardian.
Allah is one of God 99 names, he calls himself the first and the last as well. However he is the father of no one And he is one of three.
6:147 Al-An'aam
فَإِنْ كَذَّبُوكَ فَقُلْ رَبُّكُمْ ذُو رَحْمَةٍ وَاسِعَةٍ وَلَا يُرَدُّ بَأْسُهُ عَنِ الْقَوْمِ الْمُجْرِمِينَ
So if they deny you, [O Muhammad], say, "Your Lord is the possessor of vast mercy; but His punishment cannot be repelled from the people who are criminals."
6:100 Al-An'aam
وَجَعَلُوا لِلَّهِ شُرَكَاءَ الْجِنَّ وَخَلَقَهُمْ ۖ وَخَرَقُوا لَهُ بَنِينَ وَبَنَاتٍ بِغَيْرِ عِلْمٍ ۚ سُبْحَانَهُ وَتَعَالَىٰ عَمَّا يَصِفُونَ
But they have attributed to Allah partners - the jinn, while He has created them - and have fabricated for Him sons and daughters. Exalted is He and high above what they describe
6:101 Al-An'aam
بَدِيعُ السَّمَاوَاتِ وَالْأَرْضِ ۖ أَنَّىٰ يَكُونُ لَهُ وَلَدٌ وَلَمْ تَكُنْ لَهُ صَاحِبَةٌ ۖ وَخَلَقَ كُلَّ شَيْءٍ ۖ وَهُوَ بِكُلِّ شَيْءٍ عَلِيمٌ
[He is] Originator of the heavens and the earth. How could He have a son when He does not have a companion and He created all things? And He is, of all things, Knowing.
6:102 Al-An'aam
ذَٰلِكُمُ اللَّهُ رَبُّكُمْ ۖ لَا إِلَٰهَ إِلَّا هُوَ ۖ خَالِقُ كُلِّ شَيْءٍ فَاعْبُدُوهُ ۚ وَهُوَ عَلَىٰ كُلِّ شَيْءٍ وَكِيلٌ
That is Allah, your Lord; there is no deity except Him, the Creator of all things, so worship Him. And He is Disposer of all things.
6:103 Al-An'aam
لَا تُدْرِكُهُ الْأَبْصَارُ وَهُوَ يُدْرِكُ الْأَبْصَارَ ۖ وَهُوَ اللَّطِيفُ الْخَبِيرُ
Vision perceives Him not, but He perceives [all] vision; and He is the Subtle, the Acquainted.
6:104 Al-An'aam
قَدْ جَاءَكُمْ بَصَائِرُ مِنْ رَبِّكُمْ ۖ فَمَنْ أَبْصَرَ فَلِنَفْسِهِ ۖ وَمَنْ عَمِيَ فَعَلَيْهَا ۚ وَمَا أَنَا عَلَيْكُمْ بِحَفِيظٍ
There has come to you enlightenment from your Lord. So whoever will see does so for [the benefit of] his soul, and whoever is blind [does harm] against it. And [say], "I am not a guardian over you."
5:72 Al-Maaida
لَقَدْ كَفَرَ الَّذِينَ قَالُوا إِنَّ اللَّهَ هُوَ الْمَسِيحُ ابْنُ مَرْيَمَ ۖ وَقَالَ الْمَسِيحُ يَا بَنِي إِسْرَائِيلَ اعْبُدُوا اللَّهَ رَبِّي وَرَبَّكُمْ ۖ إِنَّهُ مَنْ يُشْرِكْ بِاللَّهِ فَقَدْ حَرَّمَ اللَّهُ عَلَيْهِ الْجَنَّةَ وَمَأْوَاهُ النَّارُ ۖ وَمَا لِلظَّالِمِينَ مِنْ أَنْصَارٍ
They have certainly disbelieved who say, "Allah is the Messiah, the son of Mary" while the Messiah has said, "O Children of Israel, worship Allah, my Lord and your Lord." Indeed, he who associates others with Allah - Allah has forbidden him Paradise, and his refuge is the Fire. And there are not for the wrongdoers any helpers.
5:73 Al-Maaida
لَقَدْ كَفَرَ الَّذِينَ قَالُوا إِنَّ اللَّهَ ثَالِثُ ثَلَاثَةٍ ۘ وَمَا مِنْ إِلَٰهٍ إِلَّا إِلَٰهٌ وَاحِدٌ ۚ وَإِنْ لَمْ يَنْتَهُوا عَمَّا يَقُولُونَ لَيَمَسَّنَّ الَّذِينَ كَفَرُوا مِنْهُمْ عَذَابٌ أَلِيمٌ
They have certainly disbelieved who say, "Allah is the third of three." And there is no god except one God. And if they do not desist from what they are saying, there will surely afflict the disbelievers among them a painful punishment.
5:74 Al-Maaida
أَفَلَا يَتُوبُونَ إِلَى اللَّهِ وَيَسْتَغْفِرُونَهُ ۚ وَاللَّهُ غَفُورٌ رَحِيمٌ
So will they not repent to Allah and seek His forgiveness? And Allah is Forgiving and Merciful.
5:75 Al-Maaida
مَا الْمَسِيحُ ابْنُ مَرْيَمَ إِلَّا رَسُولٌ قَدْ خَلَتْ مِنْ قَبْلِهِ الرُّسُلُ وَأُمُّهُ صِدِّيقَةٌ ۖ كَانَا يَأْكُلَانِ الطَّعَامَ ۗ انْظُرْ كَيْفَ نُبَيِّنُ لَهُمُ الْآيَاتِ ثُمَّ انْظُرْ أَنَّىٰ يُؤْفَكُونَ
The Messiah, son of Mary, was not but a messenger; [other] messengers have passed on before him. And his mother was a supporter of truth. They both used to eat food. Look how We make clear to them the signs; then look how they are deluded.
5:76 Al-Maaida
قُلْ أَتَعْبُدُونَ مِنْ دُونِ اللَّهِ مَا لَا يَمْلِكُ لَكُمْ ضَرًّا وَلَا نَفْعًا ۚ وَاللَّهُ هُوَ السَّمِيعُ الْعَلِيمُ
Say, "Do you worship besides Allah that which holds for you no [power of] harm or benefit while it is Allah who is the Hearing, the Knowing?"
5:77 Al-Maaida
قُلْ يَا أَهْلَ الْكِتَابِ لَا تَغْلُوا فِي دِينِكُمْ غَيْرَ الْحَقِّ وَلَا تَتَّبِعُوا أَهْوَاءَ قَوْمٍ قَدْ ضَلُّوا مِنْ قَبْلُ وَأَضَلُّوا كَثِيرًا وَضَلُّوا عَنْ سَوَاءِ السَّبِيلِ
Say, "O People of the Scripture, do not exceed limits in your religion beyond the truth and do not follow the inclinations of a people who had gone astray before and misled many and have strayed from the soundness of the way."
4:157 An-Nisaa
وَقَوْلِهِمْ إِنَّا قَتَلْنَا الْمَسِيحَ عِيسَى ابْنَ مَرْيَمَ رَسُولَ اللَّهِ وَمَا قَتَلُوهُ وَمَا صَلَبُوهُ وَلَٰكِنْ شُبِّهَ لَهُمْ ۚ وَإِنَّ الَّذِينَ اخْتَلَفُوا فِيهِ لَفِي شَكٍّ مِنْهُ ۚ مَا لَهُمْ بِهِ مِنْ عِلْمٍ إِلَّا اتِّبَاعَ الظَّنِّ ۚ وَمَا قَتَلُوهُ يَقِينًا
And [for] their saying, "Indeed, we have killed the Messiah, Jesus, the son of Mary, the messenger of Allah." And they did not kill him, nor did they crucify him; but [another] was made to resemble him to them. And indeed, those who differ over it are in doubt about it. They have no knowledge of it except the following of assumption. And they did not kill him, for certain.
4:158 An-Nisaa
بَلْ رَفَعَهُ اللَّهُ إِلَيْهِ ۚ وَكَانَ اللَّهُ عَزِيزًا حَكِيمًا
Rather, Allah raised him to Himself. And ever is Allah Exalted in Might and Wise.
4:159 An-Nisaa
وَإِنْ مِنْ أَهْلِ الْكِتَابِ إِلَّا لَيُؤْمِنَنَّ بِهِ قَبْلَ مَوْتِهِ ۖ وَيَوْمَ الْقِيَامَةِ يَكُونُ عَلَيْهِمْ شَهِيدًا
And there is none from the People of the Scripture but that he will surely believe in Jesus before his death. And on the Day of Resurrection he will be against them a witness.

In Islam there is more tolerance and peace is always favored, however, we are advised to defend ourselves when it is necessary and a form of defense is by word.
112. Al-Ikhlaas
قُلْ هُوَ اللَّهُ أَحَدٌ
Say, "He is Allah, [who is] One,
اللَّهُ الصَّمَدُ
Allah, the Eternal Refuge.
لَمْ يَلِدْ وَلَمْ يُولَدْ
He neither begets nor is born,
وَلَمْ يَكُنْ لَهُ كُفُوًا أَحَدٌ
Nor is there to Him any equivalent."
Prophet Jesus, peace be upon him, himself said that there will be a prophet after him called Ahmed (in Arabic language Ahmed احمد and Mohamed محمد are the same name as they derive of the same original word Hummed حُمد).
However, the Bible were that was mentioned was rejected to hide the truth.
61:6 As-Saff
وَإِذْ قَالَ عِيسَى ابْنُ مَرْيَمَ يَا بَنِي إِسْرَائِيلَ إِنِّي رَسُولُ اللَّهِ إِلَيْكُمْ مُصَدِّقًا لِمَا بَيْنَ يَدَيَّ مِنَ التَّوْرَاةِ وَمُبَشِّرًا بِرَسُولٍ يَأْتِي مِنْ بَعْدِي اسْمُهُ أَحْمَدُ ۖ فَلَمَّا جَاءَهُمْ بِالْبَيِّنَاتِ قَالُوا هَٰذَا سِحْرٌ مُبِينٌ
And [mention] when Jesus, the son of Mary, said, "O children of Israel, indeed I am the messenger of Allah to you confirming what came before me of the Torah and bringing good tidings of a messenger to come after me, whose name is Ahmad." But when he came to them with clear evidences, they said, "This is obvious magic."
