Muhammad bin Abdullah bin Numayr says that the kunyah of Sayyiduna Suhayb (may Allah be pleased with him) was Abu Yahya. He is Suhayb bin Sinan al-Namari, who belonged to (the tribe of) al-Namir bin Qasit. In his childhood he was taken captive and ended up among the Romans, and that is why he is called Suhayb al-Rumi. He lived to seventy years, and he used to dye his hair with henna. He died in Madinah in Shawwal of the year 38 AH and is buried in al-Baqi'.
