ISIS released a message it claims is from the terrorist organization's leader Saturday, asking Muslims to join him in Iraq and Syria. Many Muslims, however, took the opportunity to mock him on Twitter instead.
On Boxing Day, ISIS social media accounts released a 24-minute audio recording in which Abu Bakr al-Baghdadi presumably tries reassuring listeners that the organization remains strong despite losses in Iraq and Syria.

In his first transmission since May, the leader threatens Israel before adding that since ISIS is now surrounded by enemies on all sides and that Muslims of all stripes should join their crusade. 
"We urgently call upon every Muslim to join the fight, especially those in the land of the two shrines (Saudi Arabia), rise," al-Baghdadi says in the recording. 
Yet, many Muslims didn't quite see the point in joining ISIS. Instead, they responded with sarcasm, saying that they're simply too busy to head all the way down to the Middle East.
