"It is therefore obvious the Creed of Ibrahim is comprising of methods/ways/rites to practice Deen."
Then these methods/ways/rites to practice Deen are now only confirmed in the Quran and not the traditions of our ancestors as it says:
3:23 Have you noted those who were given a share of the Scripture? When they are invited to the Book of God to judge among them, a party of them turns away in displeasure.
5:44, “Whoever does not judge and rule according to what God has revealed, such are the disbelievers.”]
4:105 We have revealed the Book to you in absolute truth that you might judge between people according to what God has shown you (in this revelation). So, do not be an advocate for the treacherous.
When we are in need of guidance, Allah does not leave it to our ancestors to give us the details but He tells us:
6:119 Why would you refuse to eat on which God’s name has been mentioned? He has explained to you in detail what is forbidden along with certain exceptions, when in dire need. Numerous of the clergy mislead people in this matter without knowledge, and with their personal opinions. Surely, your Lord, He is best Aware of those who transgress and go beyond limits. [5:3]
7:52 We have given them a Book of knowledge that explains the guidance in full detail. It is a mercy for those who accept it. (It has the Power to change Hellish societies into paradise on earth.)
12:3 We reveal this Qur’an to you (O Prophet) and explain it in the best possible way, seeing that before this you were unaware of what revelation is.
These verses tell us that whatever was given to Abraham has now been given in the Quran to follow, not that we should follow what our ancestors have handed down to us! If it is not in the Quran, it is not a requirement from Allah.
And your accusations against me are likewise refuted by the Quran
15:1 A.L.R. Alif–Laam–Ra (Allah, Lateef the Unfathomable, Raaziq the Provider, states that), These are the verses of revelation, of Qur’an that explains itself.
15:2 The time is coming when the rejecters of the truth will ardently wish that they were Muslims.
15:3 Let them eat, drink, and enjoy life while hanging on to false hopes. They will come to know. [47:12. If they do not come to the truth, the truth will come to them, and they will see it. 102:7]
15:4 And We never annihilated any community that had not a term assigned and decreed. [All communities are given a period of respite. 13:38]
15:5 (The laws of Respite makes no exceptions.) The end of any community can neither be advanced, nor delayed.
15:6 And yet, those who deny the truth, say, “O You, to whom this Reminder has been revealed, certainly you are mad!”
You have to keep rejecting Quranic verse after Quranic verse in order to continue to believe in the falsehoods that are not in the Quran!
