Re: Interfaith Dialogue (Prophets) - Islam and Christianity
Prophets were human. And humans are always capable of sinning. You cannot find more pious models of humanity than prophets because they had exceptional help from God in order to convey Allah SWT message. However prophets were probably the most conscience about sinning and repented more than others. If a prophet is not capable of sinning he would not preach repentance as a cornerstone of faith.
I do not recall which verse in Quran but I have definitely read in certain places where Allah SWT reveals to Muhammad SAW that he could not have conveyed the message without Gods help and always warned him or explained him to stay away from sin or useless desires.
