Step-by-step explanation:
The Holy Book revealed to Hazrat Dawood is the Psalms (Zabur). This religious scripture is an important text in Islamic tradition. Hazrat Dawood, known as David in the Judeo-Christian tradition, was given the Zabur, one of the four major books in Islamic belief, the others being the Torah (given to Moses), the Injil (Gospel, given to Jesus), and the Qur'an, which is considered the final and most complete revelation given to the Prophet Muhammad. The Qur'an is the central religious text of Islam, which Muslims believe is a revelation from God. It is critically important for Muslims as it contains the foundations of their faith and outlines the principles and practices of Islam.
