Third Verse...
Third Verse: Again He says: “Whoever obeys Allah and the Apostle—they are with those whom Allah has blessed, including the prophets and the truthful, the martyrs and the righteous, and excellent companions are they” (4:69). Fourth Verse: He says: “Take whatever the Apostle gives you, and refrain from whatever he forbids you, and be wary of Allah. Indeed Allah is severe in retribution” .
(59:7) Fifth Verse: In the same Surah it is asserted: “He Whoever obeys the Apostle certainly obeys Allah.” (4:80) In all these verses of the Qur’an, as well as in numerous other verses, the obedience of Almighty Allah is made synonymous with the obedience of the prophet. Such assertion would have been impossible if the prophets were not infallible. Sixth Verse: Add this verse to the above verses: “Do not obey those who do wrong.” (25:52) Now the picture is complete.
The Prophets were to be obeyed but the wrongdoers were not to be obeyed, the only conclusion is that the Prophets were not wrongdoers.
Seventh Verse: Now comes the supplication of Prophet Abraham (PBUH) and its answer from Almighty Allah: “When his Lord tested Abraham with certain words and he fulfilled them, He said, ‘I am making you the Imam of mankind.’ Said he, ‘And from among my descendants?’ He said, ‘My pledge does not extend to the unjust.” (2:124) This verse clearly shows that the Divine Promise of Almighty Allah to appoint Imams (This word means here religious leader, including both the prophet and Imam of Muslim terminology) will not reach the sinners.
This much will be sufficient to show that our beliefs (Shia Muslims) are based on a clear understanding of the Qur’an, concerning the authority and duty of the Prophet towards Almighty Allah and towards his people. Some verses of the Qur’an It should be mentioned here that there are some verses in the Qur’an which give, to some minds, an impression that Prophet Adam (PBUH) and some other Prophets committed some sins.
The Qur’an itself declares that some of its verses are clear ones which are the basis of the Book and others are allegorical. Then it goes on to say that the true interpretation of allegorical Verses is known only to Allah and to those who are firmly grounded in knowledge. (But no one knows its interpretation except Allah and those firmly grounded in knowledge).
