Ahl al-Bayt

Not at all. Only the Imam is Infallible and not all his sons or brothers.

It is untrue. It is one of the many false accusations against us fabricated by our enemies.

We believe that followers of any Muslim sect being Sunni (Hanafi, Shafi'ee, Maliki, Hanbali, Barelwi, Deobandi or Zaidi or Abaadhi or Ash'ari or Salafi or Wahabi etc are Muslims like us.

Even those who claim that we Shia are Kafirs are misguided Muslims and we never consider them as Kafirs.

Wearing perfume has been mentioned in the Hadeeths from the Prophet (SAWA) and Ahlul Bayt (AS) as highly recommended which multiplies the reward of the Prayers seventy folds. This recommended act is for all the time and all situations. It does mean celebration as some cultures take it but it is an act of worship. It is always recommended unless your culture and your community take it as a celebrity which they don't do it in sad occasions.
Followed Islamic teachings is above following our cultures or habits.

When you believed in the fact that Ahlul Bayt (AS) are the real divine leaders of Islam after the Prophet Muhammad (SAWA) and followed them, you don't need to declare that in the form of Shahada. You should be already doing that in Azan أذان and Iqama إقامه.

It is good to say that again if you wish but it is not a condition for being a follower of Ahlul Bayt (AS) as far as you believe in it.

Shawaahid Al-Tanzeel by al-Hasakaani شواهد التنزيل للحسكاني is well known book containing many Hadeeths fron Sunni sources in favor of Imam Ali (AS).

We and all Muslims are been ordered by Allah (SWT) to take the meanings of Quran from the Prophet Muhammad (SAWA) as he is the Explainer المُبَيِّن of the Quran. (WE REVEALED ON YOU THE THIKR (FUL KNOWLEDGE OF QURAN) SO THAT YOU EXPLAIN CLEARLY TO PEOPLE WHAT WAS REVEALED TO THEM). Sura 16, verse 44).

We are the only Muslim community who fully follow this order with out fail. We take the meanings of Quranic verses from the Prophet through the most authentic narrators who are his Holy Progeny (Ahlul Bayt).

All other Muslim sects have in their books different narrations which are a mixture of authentic and not authentic or personal opinions and even Israelites.

 Writing Hadeeths were prohibited among Sunni Muslims by their leader Abu Bakr, Omar, Othman, and others for around hundred years till Omar ibn Abdul Aziz allowed it. Ahlul Bayt recorded and taught Hadeeths of the Proohet  since the time of the Prophet (SAWA) with out any gap.

The real meanings of Quran are nothing but what the Prophet explained, and that exactly was narrated by Ahlul Bayt (AS).

Deviating from Ahlul Bayt narrations is deviating from the authentic meanings of Quran and failing to obey Allah's orders to take Quranic meanings from the Prophet (SAWA) according to Quran 16:44.

We have narrations encouraging marrying from other families and not very near relatives especially when is an inherited illness in the family.

Cousin marriages took place among Ahlul Bayt (AS) like the marriage of Imam Ali (AS) and Lady Fatima (AS) , marriage of Imam Zainul Abideen (AS) and Fatima daughter of Imam Hasan (AS) and many other examples.

Not true. There is no evidence whatsoever to support such claim.

Prophets and Infallible Imams were born biologically like human beings but their status with Allah (SWT) is great and they are the most pure among all human beings. The Prophet Muhammad (SAWA) and his holy Progeny are mentioned in Quran (33:33) as The Most Purified. We believe that they are human beings and not angles, but their status is higher than all the great angles, and Allah only knows their status as our intellectual limits are less than containing their great status. The Prophetic Hadeeth says: O Ali, No one knows Allah fully but myself and you, and no one knows me fully but only Allah and you,  and no one knows you fully but Allah and myself. ( Manaqib Aal Abi Talib and Mukhtasar Basaa'r al-Darajaat and Madinatul Ma'aajiz and other books).
