How the Ahlul Bayt (a.s.) are the People of Remembrance (Ahle Zikr)

Numerous traditions have reached us which explicitly state that the 'Ahle Zikr' mentioned in the Quran are the Holy Ahle Bayt (a.s.). One such tradition is the statement of Imam Reza (a.s.) in the court of Mamun:
"We are Ahle Zikr."

Sunni scholars present at the meeting objected to this statement and maintained that Ahle Zikr in the Quran means the Christain and the Jews; and Zikr refers to the Injeel (Bible) and Taurat (Torah). Imam Reza (a.s.) replied:
"Glory be to Allah! How is it possible? How could Allah command the Muslims to refer to the Christians and the Jewish Scholars? If we refer to them they will consider their religion to be the true one and better than Islam, and will invite us to their point of view. Will you accept this invitation?"
(Oyoon-e-Akhbaare Reza).

Mamun interjected, "Can you support your claim with the Quranic proof?" The Imam said,
"Yes, Zikr means the Holy Prophet and we are his people (Ahl). To prove my point I quote the following ayat:
"O (those) who believe! Allah has indeed revealed to you a reminder (zikr), an apostle who recites to you the clear communications of Allah."
(Surah Talaq 65:10-11). 

Shahristani a Sunni scholar has reported that Imam Ja'far as-Sadiq (a.s.) and Hazrat Ali (a.s.) said:
"We are the People of remembrance (Ahle Zikr)".

Another argument is that since Allah has mentioned only in brief many of the important subjects in Quran, He must have appointed a point of reference for the guidance of the people, which would provide a detailed explanation to the subject. And this reference point is undoubtedly the Progeny of Muhammad (Aale Muhammad) in whom Allah has reposed His Knowledge and His secrets, not known to any of His other creatures. Those who desire knowledge and truth will forever be dependent on Ahlul Bayt (a.s.) and remain attached to them with love and devotion. And this devotion for the Ahlul Bayt itself is a blessing, which fetches Allah's rewards and Mercy.
