Like the title says, the early death of Jubair right before you are supposed to kill him.

Infiltrating the Madrasah Al-Kallasah
This is easy if you know how to do it. Have some guards chase you onto the roof. Then drop down to the door on the south side of the building. Engage in combat with the guards there. After a little while the guards on the roof will come down to the ground from inside the building. Since this is the only time in the game that the door is closed the guards' ai thinks they can go through. They will attack you through the door, which gives an opportunity to glitch inside by counter attacking. You need to be in combat with the guards outside since you can't lock onto the guards inside. Countering can be a little tricky because you might not be able to see the guards attack until it's too late.

Jubair's Early Death
Once you get inside you will find Jubair and the other scholars in the northwest corner of the building. They pretty much stay in the spot where they are (even grabbing and throwing won't move them). At the front of them are Jubair and the scholar he talks with during the scene. Now for pre-killing Jubair and/or the scholars. I've tried different killing combinations, each with their own results. First I killed everyone except the scholar Jubair talks with. Now for the scene... Levitating books?! Even the scholar I didn't kill doesn't appear for the scene, and the scene itself somehow won't end (when I had first originally done this I killed everyone and the scene ends as normal). Now I'll try killing just Jubair. You can identify him from the other scholars by the pouch he wears. Here's the problem with killing just him: You are exposed by the scholars, and the scene cannot start until you become anonymous. So glitch back outside the building the same way you came in. Lock onto one of the scholars so you are in combat and counter attack a guard who is outside. Then get far enough away that you escape the scholars and become anonymous (I had tried using a hiding spot but couldn't get out of it). Now for the scene... Wait, why is the scholar dead instead of Jubair?! When the scene ends you fail the mission as though the target had escaped. Now this is weird, the blade's low profile kill animation on the scholar is the same as on a target. Also one time I killed just the scholar and he still appeared in the scene as well as Jubair, but I failed the mission right after the scene ended. It's as though he is a copy of Jubair, and killing one of them affects the other. That's a very interesting thing in the game that can only be answered by Ubisoft.

Instant Kill
I wanted to try an automatic kill on Jubair like what I did with Garnier.

However I couldn't reanimate him because he can't be moved from the place he is. So I theorized it could be possible just by taking down his health with fists, since being knocked out isn't quite the same as being dead. Well it worked, but in a way that I didn't expect to happen. After I climbed up to start the scene and the dialogue appeared, "ancestor's memory synchronized recording..." Altair teleported to ground assassinate Jubair, causing the memory corridor scene to start. This is probably the only time in an AC game that a memory corridor scene has started before it should. It seems the game recognizes Jubair as a target when the scene starts. Afterwards the scene is cancelled. The invisible barriers are still there that prevent you from leaving, so I glitch my way through one of them by grasping a ledge. You aren't under city alert as you normally would, but can still complete the memory.

This video is based entirely upon a glitch reported by Bookeroo on Gamefaqs, Robert Killed In First Memory Block *Spoilers*.
He reported a glitch in memory block one where he fell through a wall, which allowed him to get to Robert de Sables. This video confirms everything he said except I found another way to get to Robert. I start off with an area exploit. Before you reach the room where you activate a trap jump from the structure on the wall and grasp a ledge on the side. You have to jump at a certain angle which allows you to slip past the corner of the wall. It also requires luck since you don't always land in the same place. Once you grasp the ledge move to the side and there are surfaces to move on. To avoid falling off the edges of narrow surfaces use the grab action. If done right you will eventually move up to where the invisible barrier wall ends and can land inside Masyaf. Here are the things said in the gamefaqs topic that have been confirmed in the video.
1. The social status indicator flashed red.
2. You can assassinate Robert de Sable. The animation I performed was low profile done on targets (so I guess this Robert has the same AI as the one in Arsuf, except for fighting you). Too bad I can't ride his horse.
3. After the assassination the sync bar turns red just like in regular assassinations where you are under city alert, but the guards don't try to fight me.
4. After leaving Masyaf and returning the camera angle moves from the leap of faith spot to you. It's kind of like when you restart from that checkpoint, when the assassin complains about his broken leg.
5. After returning Robert isn't there anymore, but most of his men are. The door to the fortress is now open. The assassins on the roof are also still there, except for Al mualim. And the assassins in the leap of faith area aren't there either.
6. Continuing by activating the trap will cause Robert to reappear for the scene.
7. An extra thing I included was proving that the wall where you activate the trap isn't solid. I managed to reach that place early in the game and show what the glitch would have probably looked like.
