According to the accounts that have come down to us the main allegations against Uthman were that he had appointed the Umayyads to high offices; that he had allowed liberal grants out of the Baitul Mal to his favorites; and that he had played into the hands of unscrupulous persons. I have discussed all these allegations in the earlier part of this book.
My conclusion is that there is no force in these allegations.
This means that most of the allegations are false, and if any allegation is factually correct, Uthman was justified in doing whatever he did.
