He is believed to have been the first person to write down the revelations of the Quran as they were received by Prophet Muhammad (PBUH).
Here's why:
* Close Companionship: Ali (RA) was a very close companion of Prophet Muhammad (PBUH) and was present during many significant events, including the revelation of the Quran.
* Early Scribe: While other companions also acted as scribes, Ali (RA) is considered the first and most trusted scribe. He was entrusted with the responsibility of recording the verses of the Quran meticulously.
* Preservation of the Quran: The role of Ali (RA) in preserving the Quran is highly significant. After the Prophet's (PBUH) death, he played a vital role in compiling and safeguarding the verses that had been revealed.
It's important to note that while Ali (RA) was the first "katib e wahi," many other companions also acted as scribes for the Prophet (PBUH) throughout his life.
