Listen to me, sisters and brothers 
Look at the horizon. They’ve got us ringed in on every side like wolves around a dying fire. Criminal empires, bloated with stolen wealth, their aircraft carriers choking the seas, their fighter jets screaming overhead, their bombers ready to turn our homes to ash. And behind all that steel and fire? Pedophiles and Satan worshippers. Men who rape children and pray to the devil before they sleep.
They are stronger than us.
They have more guns, more planes, more ships. Maybe Allah Himself has already written our names in the book martyrs.. Maybe this land is meant to burn.
But I swear on my grave and on the Name of every sons of Hassan still breathing behind these walls: we will not give them the satisfaction of surrender.
If we are doomed, then let us be the doom they never forget.
Let every bullet we fire find a throat. Let every blade we swing open a belly. Let every one of us drag ten of those devils screaming into hell with us.
No white flags.
No raised hands.
No mercy for the merciless.
Cause we are Muslims 
We don't surrender,we either Win
Or We Die

Does Muslims regardless of their borders stand in solidarity with Iran or not?

Iran is surrounded on all sides
