Illogical start to finish. Here’s a reply by someone else;
Firstly, the verse you provided and the hadeeth you provided are speaking of two different veins or arteries when looking at the Arabic text (the Qur’aan uses “al-wateen” while the hadeeth uses “al-abhar”). This alone disproves the claim.
Now if we are to understand the verses you have provided correctly, they actually reinforce the truthfulness of prophet Muhammad (PBUH) as found in numerous other verses:
“By the star when it descends, Your companion has not strayed, nor has he erred, Nor does he speak from [his own] desires, It is not but a revelation revealed” (Qur’aan / An-Najm 53:1-4)
“Nay! he has come with the truth and he confirms the messengers.” (Qur’aan / As-Saaffaat 37:37)
Furthermore, with regard to this verse:
“And then certainly should have cut off his life artery (Aorta)”
This is to be understood (according to both tafsir ibn Katheer and Tabari) that if anything/any part was false or forged, it would have been a swift punishment or occurrence of having the aorta cut, which would cause instant death. It would not be delayed until after the message had been completely delivered, and in this case, perfected as Allaah later revealed in the Qur’aan:
“This day, I have perfected your religion for you, completed My Favour upon you, and have chosen for you Islam as your religion.” (Qur’aan / Al-Maa’idah 5:3)
Allaah did not cut the aorta of the prophet Muhammad (PBUH), plain and simple and the prophet (PBUH) did not hve his aorta cut!
1). why would Allaah Send Blessings on a false prophet?
“Allah sends His Graces and Blessings on the prophet …” (Qur’aan / Al-Ahzaab 33:56)
2). why would Allaah say that Muhammad (PBUH) is surely a messenger and is true, if he was false?
“These are the Verses of Allah, We recite them to you in truth, and surely, you are one of the messengers.” (Qur’aan / Al-Baqarah 2:252)
“How shall Allah guide a people who disbelieved after their belief and after they bore witness that the messenger is true and after clear proofs had come unto them? And Allah guides not the people who are wrong-doers.” (Qur’aan / Aal-’Imraan 3:86)
“O humankind! Verily, there has come to you the messenger with the truth from your Lord, so believe in him, it is better for you. But if you disbelieve, then certainly to Allah belongs all that is in the heavens and the earth. And Allah is Ever All Knowing, All Wise.” (Qur’aan / An-Nisaa 4:170)
3). Why would Allaah Command the believers to obey the messenger numerous times throughout the Qur’aan if he was false?
3:32 / 3:132 / 4:42 / 4:59 / 4:69 / 4:80 / 5:92 / 24:54 / 24:56 etc.
Finally, it should also be mentioned that the statement uttered by the prophet (PBUH) about his aorta being cut was a common idiom used by Arabs in that time when referring to death in any form and is not necessarily to be taken literally.
