And your Lord is most knowing of whoever is in the heavens and the earth. And We have ranked some of the Prophets upon others, and to Dawood, We gave the Psalm.
All Messengers are Prophets while all Prophets are not Messengers. Lord’s Message is sent upon the Messengers. All 313 Messengers are sent down with Adhikr as explained in verse 21: 24. The name of the Book sent down to Messenger Dawood is Psalm which is in the Greek language and Its soul is Adhikr itself. Adhikr revealed to Messenger Muhammad is safeguarding and testifying all 312 previous Books revealed before as explained in verse 16: 44.
The Arabic Quran reading Fujjar are differentiating among Messengers rejecting verses 2: 136 and 285. Thus these true disbelievers mentioned in verses 4: 150-151 do not believe in any Prophet or Messenger. These Fujjar are following 29 pseudo-prophets and are hurrying for the Antichrist. See explanation 2: 253; 10: 60-61 and 17: 47-48.
