In this answer, the OP states that Jesus is the only prophet with the honor of being called sinless.
If this is true, according to sacred texts, why does he have that honor? What was the purpose of him being sinless?
The answer is for all to see:
Pickthall: faultless son.
Yusuf Ali: gift of a holy son.
Shakir: a pure boy.
Dr. Ghali: a most cleansed youth."
This leads me to believe that Jesus was indeed the only sinless man, as far as Prophet Muhammad told us. In contrast, the Quran tells us that Muhammad sinned no less than 3 EXPLICIT times! @Owari, you also beleive the 12 imams are sinless as well. But Allah only names one explicitly in his manifest book, 'Isa ibn Maryam.
Why does he have that honor? With respect, this is the wrong question. He is repeatedly described as the Christ, Al-Masih, but most muslims do not understand the implications of this word. Look at the earliest tafsirs to understand what the Earliest Muslims really believed(Like Razi).
What was the purpose of him being sinless? Who knows? Maybe he will intercede instead of Muhammad. After all, the Quran does not state WHO will intercede(If there will be any). He will also be a 'sign on the last day.' This leads to huge theological and philosophical debates that no one has time for. The fact is, he is sinless. Salaam.
