A number of Quran activists and families of some of the martyrs took part in the ceremony.
The human crush in Mina in September 2015 killed thousands of pilgrims, including hundreds of Iranians.
The incident cast doubt on the kingdom’s efficiency in hosting the rituals.
Unofficial sources put the death toll at almost 7,000 people. Iran said about 465 of its nationals lost their lives in the incident.
They included a number of Iranian Quranic figures.
