With regards to the topic of the cause of the Holy Propeht’s death [whether he (s) died of natural death, or was killed], some people have come forth with the argument that goes:
“If the Prophet (s) wasn’t martyred, then all those who were martyred managed to gain a virtue that he didn’t!”
Answer:
What an argument?!
“Whoever dies with the love of Ali is a Shahid (martyr)”, says the Prophet, quoted even by Zamakhshari who is a Sunni, let alone whoever dies a Prophet, nay the highest ranked Prophet, nay the first and most perfect creation of God. He is already in قاب قوسین او ادنی
