Imam Ahmed relates that Ibn Al-Abbas said: "A man asked Rasulullah SAW about Saba – was it a man, a woman, or a land – and Rasulullah SAW said it was a man and he had 10 sons, 6 of them lived in Yemen and 4 of them lived in the area of Syria (Sham). Those who lived in Yemen are the tribes of Midhhaj, Kinda, Al-Azd, Al-Ash'ariyeen, Al-Anmaar, and Himyar. As for those who lived in Syria, they are the tribes of Lakhim, Judhaam, 'Aamila, and Ghassaan."

Take whatever you have obtained until now and return to your homes safely."
Ubada ibn Al-Samit said, "Oh Jabla. Don't you know how we faced your advanced forces at Ajnadain and other places and how Allah SWT granted us victory over you and how your tyrant ran away? We know who remains from your forces and they are easy for us. We are not afraid of these forces that have come. We have tasted blood and we haven't found blood sweeter than the blood of the Romans! Jabla, I call you to the religion of Islam and to enter our religion with your people and keep your honor in this life and the next life. Don't be a servant of these uncouth Romans and put your life on the line to save them from destruction. You are from the chiefs of the Arabs and a king. Verily our religion has appeared.
