Our Master Muhammad [s] ordered the best fifty bow men to stay on al-Ainain Mount. Their duty was to defend the Muslims against any surprising attack. Thus, the Prophet [s] ordered them not to leave their places at any rate - he said to them:

Our Master Muhammad [s] ordered Ali bin Abu Talib [a] to raise the banner high. The fight continued. Then Hamza became a martyr. Some companions fought bravely. Abu Dajana al-Ansary and Sahal bin Hunaifa were two of them.

Some companions heard an angel calling the sky:
