He (SWT) Himself is speaking to testify the truth regarding the identity of AhlulBayt who are exclusively Ali, Fatima, Hasan, and Husain (May Allah be pleased with them). The next question to ask is: What the significance of “AhlulBayt” in Allah’s eyes? The answer to that is conveyed in the second part of Allah’s answer and that is - معدن الرسالة (the core of the Message) As we know, Allah (SWT) has revealed the message of Islam as the final revelation to mankind till the end of time.
In the words of the Prophet (SA), he has left behind two weighty things - the Holy Qur’an and his ‘Itrah (AhlulBayt) – which will always accompany each other and will never separate until they reach the Pool of Hawd. We as Muslims are ordered to adhere to the Qur’an and AhlulBayt which together serve as our lanterns of guidance for salvation.
The Qur’an consisting of the word of God coupled with the infallible teachers and divinely appointed guides represented in the AhlulBayt (AS) and the Imams who will clarify the message of Islam and act as the “speaking Qur’an” and the “walking Qur’an” is the correct formula and prescription for us to abide by if we wish to achieve spiritual success and proximity to God. The AhlulBayt (AS) is the model for human perfection and the template which we should follow and take our example from.
In fact, all of the prophets and messengers before the Seal of Prophets understood their position of Wilayah and superiority over them and that they are the part and parcel of the unified message which Allah (SWT) intended for mankind to embrace. They are the heart of the religion and the core of the message as Allah (SWT) testifies, hence there cannot be any doubt or argument over this fact.
(6:124) After properly introducing their title and significance to the religion, Allah (SWT) then identifies them personally by presenting only one of the five personalities who are under the cloak – and she is Lady Fatima.
