At the Battle of Uhud, when the Muslims fell into disarray at the beginning of hostilities the Prophet became dangerously exposed. There were about eleven men of the Ansar at his side and one Muhajir - Talhah ibn Ubaydilla.
The Prophet clambered up the mountain hotly pursued by some mushrikin (non-believers). The Prophet, peace be on him, shouted:
"The one who repulses these people from us will be my companion in Paradise."
"I, O Messenger of Allah," shouted Talhah..
"No, stick to your position," replied the Prophet. A man from the Ansar volunteered and the Prophet agreed. He fought until he was killed. The Prophet went further up the mountain with the mushrikin still in close pursuit. "Isn't there someone to combat these?"
Talhah again volunteered but the Prophet ordered him to maintain his position. Another person immediately came forward, fought and was killed. This happened until all who stood by the Prophet were martyred except Talhah.
"Now, yes," signalled the Prophet and Talhah went into battle. By this time, the Prophet's teeth had been broken, his forehead had been slashed, his lips had been wounded and blood was streaming down his face. He was drained of energy. Talhah plunged into the enemy and pushed them away from the Prophet. He turned back to the Prophet and helped him a little further up the mountain and put him to lie on the ground. He then renewed his attack and successfully repulsed the enemy
