In The Name of Allah The Beneficent The Merciful

Asalaam-u-Alaikum,  

Amongst many of the blessing during the holy month of Ramandan, Allah (s.w.t) also revealed his holy books to his prophets during this month.  Today, on 18th of Ramadan Zabur (Psalms of David) was revealed.  

Zabur (Arabic: زبور) is, according to Islam, the holy book of Dawud (David), one of the holy books revealed by God before the Qur'an, alongside others such as the Tawrat (Torah) of Musa (Moses) and the Injil (Gospel) of Isa (Jesus).

Some scholars equate the Zabur with the biblical book of Psalms. The term zabur is the Arabic equivalent of the Hebrew zimra, meaning "song, music." It, along with zamir ("song") and mizmor ("psalm"), is a derivative of zamar, meaning "sing, sing praise, make music."

The Zabur of Dawud (David) is referred to in the Qur'an as one of God's books revealed to four selected messengers. The Zabur is preceded by the Taurat (Torah) given to Moses and followed by the Injeel (Gospel) given to Jesus and finally the Qur'an given to the Islamic prophet, Muhammad (s.w.a).

According to Islam, it has been there even since the time of Adem (Adam, who is considered the first human) and not beginning in the 7th century. The Aqeedah (belief system) of Islam is believed to be exactly the same in every single one of the four scriptures and several scrolls and is thought exactly the same by every prophet. Considering this it can be assumed the theological aspects of the Zabur be exactly the same as the Qur'an.

The Sharia or laws of Islam however are known to have changed slightly depending on the prophet of the time, although the Sharia that is revealed in the Qur'an is final till the end of time as there will be no prophet after Muhammad, and no book after the Qur'an. Hence the laws of the Zabur need not be exactly the same as what is Islam of today (as in the Sharia of the Qur'an).

In the Qur'an, the Zabur is mentioned by name only three times. The Qur'an itself says nothing about the Zabur specifically, except that it was revealed to David, king of Israel and that in Zabur is written "My servants the righteous, shall inherit the earth".

"And it is your Lord that knoweth best all beings that are in the heavens and on earth: We did bestow on some prophets more (and other) gifts than on others: and We gave to David (the gift of) the Psalms." -Qur'an, Sura 17 (Al-Isra), ayah 55

"Before this We wrote in the Psalms, after the Message (given to Moses): My servants the righteous, shall inherit the earth." -Qur'an, sura 21 (Al-Anbiya), ayah 105
