The only Sahabi whose name is directly mentioned in the Holy Quran is Hazrat Zaid Bin Haris (RA).

Hazrat Zaid (RA) was a very close companion of Prophet Muhammad (SAW). He was adopted by the Prophet and loved like a son. People even called him "Zaid bin Muhammad" before adoption laws were revealed.

Later, Allah revealed a verse in Surah Al-Ahzab (33:37) where his name, Zaid, is clearly written. In that verse, Allah talks about an event related to Zaid’s marriage and divorce.

This is a great honor for Hazrat Zaid (RA) because out of all the companions, only his name was written in the Quran by Allah’s command. This shows how important and beloved he was in Islam.

He was also a brave fighter and a loyal servant of Islam. He joined many battles and served the Prophet (SAW) until he was martyred.

His example teaches us about love, loyalty, and obedience to the Prophet and Allah. He will always be remembered in Islamic history.
