Anas (radi Allahu anhu) said the Messenger of Allah (sal Allahu alaihi wa sallam) took up a sword on the day of the battle of Uhud and said, “Who will take this sword from me?” Everyone stretched forth his hand saying: “I will take it; I will take it”. He (sal Allahu alaihi wa sallam) said, “Who will take it with its full responsibility (i.e., to use it to fight Allah’s enemies with it)?” The Companions hesitated. Abu Dujanah (radi Allahu anhu) said: “I shall take it;” and with it he cracked the skulls of the pagans
This Hadith mentions the chivalry and distinction of Abu Dujanah (radi Allahu anhu) but it should not be taken to mean that other Companions of the Prophet (sal Allahu alaihi wa sallam) showed cowardice on that occasion. The latter had in fact hesitated to get the honour and reward attached with the Prophet’s sword. It is evident from the fact that when the Prophet (sal Allahu alaihi wa sallam) offered it without any condition everyone stretched his hand to take it.
And Allah Knows Best!
