Outside of Rasulullah SAW religious proselytizing to many nomadic tribe, he also did it to an individual, such as:
1) Suwaid bin Shamit
He is a clever poet. One of Yastrib people. He made pilgrimage to Mecca. Then Rasul invited him to join Islam.
"May your report as good as mine". He said.
"What do you have? Show me" Prophet said.
Then Suwaid told him philosophy of Luqman. And then Prophet said "That is a fine word, but my philosophy is so far principal".
So he read of Al-Qur'an and invited Suwaid to join Islam.
"You are right, that is really fine word". Suwaid said.
And then he join to Islam.
But not long after that, he killed on Bu'ats battle.
Sallu'alaika.
