Sa'd ibn Ubadah
When Muhammad heard that Abu Sufyan's caravan was returning from Syria, he consulted the Muslims over whether to attack. He did not listen to either Abu Bakr or Umar. Then Sa'd ibn Ubadah stood up and said: "Allah's Messenger, you want us [the "Ansar" to speak]. If you ordered us to plunge our horses into the sea, we would do so. If you ordered us to goad our horses as far as Bark al-Ghimad, we would do so." Muhammad then called upon the men to march to Badr.
