But nouman said that the word aqeeda - which relates to creed and cannon - doesn't exist in the Quran, whereas Allah :swt: speaks of the "millah" of ibraaheem who was ultimately described as an ummat in his own right due to his exclusive sincerity in seeking and following the truth despite the strayings of his community - and the respected scholar was speaking of tawheed -which nouman doesn't deny.
The only non-quranic statement (but which is manifest all over it) which can be described as creed - is the shahaadah of Islaam.
Al-Baqarah 2:135
وَقَالُوا۟ كُونُوا۟ هُودًا أَوْ نَصَٰرَىٰ تَهْتَدُوا۟ۗ قُلْ بَلْ مِلَّةَ إِبْرَٰهِۦمَ حَنِيفًاۖ وَمَا كَانَ مِنَ ٱلْمُشْرِكِينَ
They say: "Become Jews or Christians if ye would be guided (To salvation)." Say thou: "Nay! (I would rather) the Religion of Abraham the True, and he joined not gods with Allah."

Al-Baqarah 2:140
أَمْ تَقُولُونَ إِنَّ إِبْرَٰهِۦمَ وَإِسْمَٰعِيلَ وَإِسْحَٰقَ وَيَعْقُوبَ وَٱلْأَسْبَاطَ كَانُوا۟ هُودًا أَوْ نَصَٰرَىٰۗ قُلْ ءَأَنتُمْ أَعْلَمُ أَمِ ٱللَّهُۗ وَمَنْ أَظْلَمُ مِمَّن كَتَمَ شَهَٰدَةً عِندَهُۥ مِنَ ٱللَّهِۗ وَمَا ٱللَّهُ بِغَٰفِلٍ عَمَّا تَعْمَلُونَ
Or do ye say that Abraham, Isma'il Isaac, Jacob and the Tribes were Jews or Christians? Say: Do ye know better than Allah? Ah! who is more unjust than those who conceal the testimony they have from Allah? but Allah is not unmindful of what ye do!

Aal-e-Imran 3:67
مَا كَانَ إِبْرَٰهِيمُ يَهُودِيًّا وَلَا نَصْرَانِيًّا وَلَٰكِن كَانَ حَنِيفًا مُّسْلِمًا وَمَا كَانَ مِنَ ٱلْمُشْرِكِينَ
Abraham was not a Jew nor yet a Christian; but he was true in Faith, and bowed his will to Allah's (Which is Islam), and he joined not gods with Allah.

I recall that speech from tafseer of yaa seen, he was talking about a (probably sincere) lady who brought him a book about grave worship and saints and many the things that some scholars were advising people against, whereas those things are obvious to a student of the Quran and hadeeth but useful to greenies who fall into or observe such faults,
I can see why he didn't like to spend too much time on it because it was obvious stuff that is only news to the people of shirk and bida'ah.
I felt fatigued from negative energy after reading a part of one myself due to the copious arguments which didn't apply to me or to most people on earth ANYWAYS - though i can see how it removes misconceptions which some people might have and how it clarifies the simple truth of Islam to those who might be confused about whether it's a part of Islam to pray TO graves of saints etc, so i'd say it's a good thing to hilight in books based on the topic. Though i believe Nouman was simply focusing on priorities given the limited time he has with his audiences.
Though he could of course have also given a lengthy talk on "don't pick your nose and eat it!"
