He causes his sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous. If you love those who love you, what reward will you get? Are not even the tax collectors doing that? And if you greet only your own people, what are you doing more than others? Do not even pagans do that? Be perfect, therefore, as your heavenly Father is perfect.
In 1921, soon after the passing of 'Abdu'l-Bahá, this is what Mírzá Muhammad 'Alí wrote about the man who rivalled against him for nearly 30 years:
Mirza Muhammad Ali
I deeply regret to have to record the great and unspeakable bereavement we have recently sustained by the departure of the venerable Ghusn-i-A'zam, Abbas Effendi, Sir 'Abdu'l-Baha, who was the backbone and support of his friends and the pride of his followers.

Muḥammad-Javád-i-Qazvíní, a notorious Covenant-breaker, perished miserably. Shu'á'u'lláh who, as witnessed by 'Abdu'l-Bahá in His Will, had counted on the murder of the Center of the Covenant, and who had been dispatched to the United States by his father to join forces with Ibráhím Khayru’lláh, returned crestfallen and empty-handed from his inglorious mission. Jamál-i-Burújirdí, Mírzá Muḥammad-‘Alí’s ablest lieutenant in Persia, fell a prey to a fatal and loathsome disease; Siyyid Mihdíy-i-Dahájí, who, betraying 'Abdu'l-Bahá, joined the Covenant-breakers, died in obscurity and poverty, followed by his wife and his two sons;
