Can `Ali defeat an army on his own?

[Hani]

al-Salamu `Aleykum,


A question to Shia Imamis, I just heard that Shia believe `Ali ibn abi Talib defeat an entire army on his own? Is this correct?

[Bolani Muslim]

I was once told that Allah had to tell Abul Fazl Abbas to stop killing the army of Yazid or else he would've killed everyone. I'm not sure if it's a Shia rumour or something actually in Shia books. 

[Hani]

I need an answer form an Imami, simply because I wish to follow it by the question: "Why did the Muslims lose in Uhud"?

[MuslimK]

They say all victories were due to the heroism of Ali, and the defeat were due to the cowardice of rest of the Muslim army.

[Hani]

Let's ask this new Imami Shia on the website "labelingtheory", is it true that `Ali can defeat an entire army by himself?

Only if there is i'jaz. Otherwise, normally, no.
