Abdu'l-Baha's self-centeredness in the execution of religious rulings

What can be understood from the lives of the divine prophets is that they made every effort to propagate and maintain the divine religion and ultimately implement the religion. Then, by God's command, the successors were introduced to the people to continue that way. Baha’is who consider their faith as a divine religion claim that Baha-u'llah, introduced Abdu'l-Bah as his successor. And he had the utmost obedience, servitude, and devotion to Baha- u’llah. However, Abdu'l-Baha not only did not obey many of his commandments, but also added new commandments and issues that he had not said before, and even abrogated some of his commandments! In addition, although the exact implementation of all the rules of a religion is expected from the Prophet's successor, this is not the case in the Baha'i Faith, and 'Abdu'l-Baha did not follow some of the rules of that Faith. Thus, the legitimacy of Bahaism , as well as the claim of Abdu'l-Baha's obedience is questioned or even is denied.
