Mus'ab ibn Umayr
companion (Sahabi) of Muhammad

Muṣʿab ibn ʿUmayr (Arabic: مصعب بن عمير) also known as Muṣʿab al-Khayr ("the Good") was a sahabi (companion) of Muhammad. From the Banū ʿAbd al-Dār branch of the Quraysh, he embraced Islam in 614 CE and was the first ambassador of Islam. He died in the Battle of Uhud in 625 CE.
Early life
Mus‘ab ibn Umair was born to the Banu Abd al-Dar branch of the Quraysh tribe. His exact birth year is not known; it is believed that he was born sometime between 594 and 598 CE since he was very young when he embraced Islam in 614. Mus‘ab was the son of Umayr ibn Hashim and Khunas bint Malik, and his parents were wealthy. Even as a young man, he was permitted to attend meetings of the Quraysh elders.
Conversion to Islam
The first Muslims used to meet with Muhammad at the house of Al-Arqam known as the Islamic Learning Center. Mus'ab became interested and went to this house to find out more about Islam. As a result of hearing the reciting of the Qur'an and the preaching of Muhammad, he converted.
At first Mus'ab kept his faith a secret, for he was afraid of how his mother would react.
