Allah Taala said in the Quran:
[Shakir 61:2] O you who believe! why do you say that which you do not do?
[Shakir 5:54] O you who believe! whoever from among you turns back from his religion, then Allah will bring a people, He shall love them and they shall love Him, lowly before the believers, mighty against the unbelievers, they shall strive hard in Allah’s way and shall not fear the censure of any censurer; this is Allah’s Face, He gives it to whom He pleases, and Allah is Ample-giving, Knowing.
[Shakir 2:104] O you who believe! do not say Raina and say Unzurna and listen, and for the unbelievers there is a painful chastisement.
[Shakir 2:208] O you who believe! enter into submission one and all and do not follow the footsteps of Shaitan; surely he is your open enemy.
[Shakir 4:43] O you who believe! do not go near prayer when you are Intoxicated until you know (well) what you say, nor when you are under an obligation to perform a bath– unless (you are) travelling on the road– until you have washed yourselves; and if you are sick, or on a journey, or one of you come from the privy or you have touched the women, and you cannot find water, betake yourselves to pure earth, then wipe your faces and your hands; surely Allah is Pardoning, Forgiving.
[Shakir 8:27] O you who believe! be not unfaithful to Allah and the Messenger, nor be unfaithful to your trusts while you know.
[Shakir 49:2] O you who believe! do not raise your voices above the voice of the Prophet, and do not speak loud to him as you speak loud to one another, lest your deeds became null while you do not perceive.
[Shakir 63:9] O you who believe! let not your wealth, or your children, divert you from the remembrance of Allah; and whoever does that, these are the losers.
Well, if we would base our answer on sunni books, we have explanation for all these verses.
But if we would base our answer on shia books, we should say: ALL OF THESE VERSES WERE REVEALED ABOUT AHLALBAYT, AND HEAD OF THEM – ALI IBN ABU TALIB.
al-Majlisi in “Biharul anwar” (33/333, also see Tafsir Furat al-Kufi, p 49) narrated:
عن النبي صلى الله عليه وآله أنه قال : ما أنزل الله تعالى آية في القرآن فيها ” يا أيها الذين آمنوا ” إلا وعلي أميرها وشريفها .
From messenger (sallalahu alaihi wa ali): “Allah didn’t reveal verse that begins with ‘O you who believe,’ without Ali being their (mentioned believers) head, and their distinction”
Other giant of rafidah, Sayed Hashim Bahrani in “Ghayatul maram” , chapter 230, quoted from Sahifa ar-Rida:
صحيفة الرضا (عليه السلام) قال: ليس في القرآن آية (يا أيها الذين آمنوا) إلا في حقنا
Sahifa ar-Rida (alaihi salam) says: “There is no verse in Quran (starting) from “O you who believe!”, except as in our rights (about us)”.
