صُهَيبُ بنُ سِنَان
Abu Yahya
Suhayb al-Rumi RA, Abu Yahya, was one of the earliest Muslims of Makkah and one of the first seven to declare Islam openly, often named with his friends Ammar ibn Yasir RA and Bilal RA. An Arab by birth, he was captured as a boy and raised among the Romans, then came to Makkah in the household of Abdullah ibn Jud'an, where he grew wealthy as a business manager and was freed. When he emigrated, the Quraysh stopped him, and he gave up his entire fortune to go, reaching Quba' on foot and exhausted; the Prophet ﷺ told him, "Your trade has been successful," and a verse of Surah al-Baqarah was revealed about the man who sells himself seeking Allah's pleasure. He lived among the People of the Suffah in Madinah.
