I would not adjust the rod just yet. Open the bleeder valve on the slave, you should be able to push the slave back in and line up the bolt holes.

Do you know how to bleed the system? You obviously will need to do that when you get everything back together.

Sure, the piston will go back in when the bleeder is cracked open, but he needs to correct the issue on the master cylinder. Based on his description, it sounds like the rod is pushed too far in not allowing the master cylinder piston to fully retract. This is blocking the relief port in the master not allowing fluid to be pushed in reverse (back to the reservoir). This is critical to a hydraulic master/slave cylinder operation to allow the unit to self adjust as the clutch wears down.

I adjusted the pedal rod to remove the free play before. Does that affect anything?

YES! it affects everything I mentioned in my previous post. Adjust the clutch rod to the point where you can push the slave cylinder back in using hand pressure. This way, you know you haven't gone too far and still allowing the system to do it's job.

I'm also assuming your clutch pedal switch is properly adjusted, allowing the master cylinder to fully disengage and not placing any preload on the pedal.

May want to check the firewall on the inside right below the master cylinder for any fluid. You could've busted a seal with that much 'handling'

I am planing to do this soon and I done want to screw up, what is the main cause of this?

Did the piston pushed out by the pressure and it has to be reseated by bleeding the clutch completely and then the piston can be reseated?

If that's the case how can I safely pull out the slave cylinder and lube the head and put it back?

Thanks for the hints!

Well the end part that has the ball in it will actually slide out of the piston itself. Once you do that put a zip tie around the piston and the whole slave to keep it compressed while you work on the ball.
