Is the statement that an error in understanding is excused in the branches but not in the fundamentals correct?

The Shaykh : You often read or hear that an error in understanding is excused in the branches but not in the fundamentals. This is wrong. An error is excused absolutely, whether it is in the branches or in the fundamentals. The reason there is no accountability from Allah (Mighty and Majestic) for His servants is the absence of the intention to disobey from that servant toward his Lord. So if there is disobedience, whether the disobedience is in the creed or in the ruling in Islamic jurisprudence, and there is no intention, stubbornness, arrogance, or denial, then there is no accountability for that. The distinction between the fundamentals and the branches, between the creed and Islamic jurisprudence, in the matter of not being held accountable for an error in the branches but being held accountable in the fundamentals—this distinction has no basis. This distinction is exactly like the other innovated distinction, which is that it is obligatory to act upon a report with a limited chain in the branches, but one does not act upon a report with a limited chain in the fundamentals. This is wrong, and this is wrong.
