Baha’is around the world celebrate what is known as The Day of the Covenant on 4 Qawl, according to the Baha’i calendar.

The Day of the Covenant is a commemoration of Baha’u’llah’s appointment of His eldest son, Abdu’l-Baha as His successor. Abdu’l-Baha played a crucial role in guiding the early Baha’i community and ensuring that the followers of the Baha’i Faith remained united, rather than fragmenting into different sects.
