The Quran, Psalms and Proverbs can not be invalidated because of misinterpretations of events in the lives of the Anbiya nor in the correct interpretations

ASA WR WB to believing Muslim friends

You may not have heard this one. So, I'm sharing it.
Sometimes when a Muslim contributes to inter-Faith discourse with a "Correction" or "Corrected Perspective" on Scriptures via Law from Quran or Kitab (sometimes the corrected perspective is in the Kitab, example was Dr Naik's post yesterday from the "Good Teacher" passage of the Injeel) we might get an attempt to discredit or invalidate that contribution due to a Hadith.
The Hadith is the account of Abu Bakr (ra) promising Aisha (ra) to Nabi Muhammad (saws), what was it? at age 6 or 9? It subsequently turns into an invalidation and discredit of the Nabi (saws) due to implicating the behavior as a pedophile, and thus any advice unworthy and irrelevant from him (saws), or possibly more specifically the group, or even more specifically the sub-group of the group who interpret his marriage to a 6 or 9 year old lawful behavior.
The problem with this, and I have not looked at this hadith in many years so going off of memory today, is that we were not really given any idea of when the marriage happened or was consummated. In other words the Nabi (saws) might have been promised her when she was 6 or 9 as an arranged marriage but did not actually consummate the engagement or marriage until she was 18 or 21 years of age. We don't, or at least, I didn't see any more details of that, so it leaves open the possibility it was a promise or arrangement that may have not been fulfilled until she was of age.
It all comes back to regardless of what happened we still have to receive the Corrections of Allah (swt). Nabi Daoud (epbuh) slept with Bathsheba, the wife of Uriah the Hittite who was one of David's best soldiers who refused to leave his post in service to David. David had already committed the act with Bathsheba and it became clear she had become pregnant and David wanted Uriah to think it was his. Because Uriah refused to go home and be with his wife, Nabi Daoud (epbuh) sent Uriah to the thick of a combat situation and then withdrew the other soldiers and Uriah was felled in battle. This prompted a Judgment from Allah (swt) through Nathan the Priest (as). Bathsheba would later give birth to King Solomon (epbuh). There were rumbles about the character and ethics of Solomon (as) and the many wives and if he had committed blasphemy at the Pagan Temples of some of his wives to which Allah (swt) defends Nabi Sulaimon (as) at Baqarah Ayat 102-103, "The blasphemers were not Solomon, but the evil ones teaching magic and such things as came down to the Angels Harut and Marut at Babylon..."
But either way whether it is Nabi Muhammad, Nabi Daoud, or Nabi Sulaimon (epbut) it is not our place to judge them. Only Allah (swt) can Judge His Anbiya (epbut). It is for us to accept the Corrections that they brought in the Holy Words of Allah (swt) through them kept in writing in Allah's Holy Books.
The Quran, Psalms and Proverbs can not be invalidated because of misinterpretations of events in the lives of the Anbiya nor in the correct interpretation as in the case of King David (epbut). David did what he did, but we still got to respect the Psalms.
