Al-Najdi instructs his readers in some possible ways to kill a Westerner, from choosing the victim through following him through the stage of the actual killing.
The following are excerpts from the document: 
Before Carrying Out the Operation, Pray for Guidance
"Below I will explain the jihadist way of action and the security measures to be employed by the jihad fighter [when he wants to kill a Westerner]:
"First of all, before carrying out the operation, pray [to Allah] to guide you on the good path.
"[Regarding your] external appearance - Try as much as possible to look like someone who is not religious. For example, wear [a kuffiyeh] with an 'aqal instead of a turban, and wear cheap dark glasses during the day and regular glasses at night. Your clothes must be long, and try if at all possible for them to be heel-length, or longer; don't be afraid of this. Wear a sport suit or a regular suit. Similarly, it is greatly preferable to be shaven.
"[Regarding] the items or the clothing in [your] car - Immediately get rid of everything in your car that indicates that you are religious, such as jihad cassettes, small papers such as post-its... The most important thing there must not be anything in the car indicating that the owner is a religious man... so that if the dogs of the security [apparatuses], the emergency [apparatuses], or the other [apparatuses] stop you in a suspicious place and search your car they will find nothing proving that you are religious, and will release you right away.
"While you are carrying out the operation, be careful not to take your cell phone with you - especially if it has a camera - so that it won't cause you, or your friends whose numbers are in the phone, problems with unknown consequences.
Some Ways to Find a Crusader [i.e. a Westerner] or a Dog From the Security Apparatus
"In order to carry out the operation when the time comes, you must have a weapon (a pistol or a submachine gun) or a good knife, if you are interested in slaughtering this infidel or this [Saudi] dog...
"[How to find a target] in the Crusader settlements [i.e. compounds] that are found everywhere:
"The first method: At about seven AM, pass by the settlement and check only how these Crusaders leave it, and what road they take. Beware, my jihad-fighting brother, to pass by only once, because the military dogs at the gates [of the settlement] might suspect you and detain you.
"Two or three days later, pass by the [same] settlement, but don't go near it as you did the first time. That is, go straight to the road where [the settlement residents] go, and wait for them by the side of the road, and when you see one of these Crusaders, follow him.
"It is best to change vehicles each time, if you can. While following the Crusader, be very careful not to be exposed. For the most part, especially these days, they are feeling safer, because there are not many operations against them. But the jihad wave is approaching, and Allah will conceal this matter from them....
"When [the Westerner you have selected] stops at a traffic light, try to be behind him, in the same lane, with at least two cars between you and him, or alongside him, but not exactly alongside him. While waiting at the traffic light, refrain from casual glances, and try to occupy yourself with something (such as arranging your 'akal...). When you two turn onto the highway, try to pass the infidel on the right or left, and then slow down so that he will pass you, so as to remove suspicion for the next time.
"When you and the infidel move to the secondary road, and you are following him and there is no one on the road but the two of you, first slow down and pretend you're looking for a shop or a place or a person, by turning your head right and left as if searching for something, [thus showing] that this infidel does not interest you at all.
"A second way to find [a Westerner]: Sometimes there is no need to follow the infidel first thing in the morning; often we see them next to traffic lights or at the big marketplaces... (such as Karfour, Extra, and so on); often, they shop there, particularly in the morning, between 9:30 and 12:00. When you see [an infidel in one of these places], follow him carefully, and you will [quickly] notice that for the most part he will be going to a settlement or to a house in one of the neighborhoods...
"A third way to find [a Westerner]: Sometimes when you, the jihad fighter, are sitting with your colleague or with family, someone comes and says: 'We have an American working for the company, who receives [a salary of] 150,000...' When you hear this, you must find out the following things:
"1) If you know where your colleague works - fine. But if you don't know where he works and where his company is, immediately address your colleague, saying: 'That's not true, this [salary] is exaggerated.' He will immediately say, 'You're wrong, and I can prove it.' Tell him, 'I know someone who works for such-and-such a company (give a name) and they have an American who gets [paid] 40,000, and their company is in (give a place). Then tell him, 'Your company is probably in the such-and-such area (north, for example).' And he will reply: 'No, our company is in such-and-such a place.' If the description so far is [still] unclear to you, say to him: 'Oh... next to (give the name of a place)?' He will reply, 'No, our company is in such-and-such a place' exactly. Then say to him, 'This American you have must be a director if he gets [paid] such a sum,' and then he will tell you what this infidel does [in the company]. Then say, 'Surely he has a fancy car if he gets such a salary,' and then he will tell you the kind of car. Thus you have gotten the information that will help you in the future, without your colleague or anyone around him noticing. Then pretend that the matter doesn't interest you, and try to change the subject immediately.
"2) If you know where your colleague works but you are interested in information about this infidel, question him in the manner I described above, and take care that they don't notice that you are looking for this infidel.
How to Kill the Infidel and What Security Measures to Take
"The best way to carry this out is to forge an ID card and a work ID, in order to rent a car. If you can't do this, act as follows:
"1) Take the license plate from any car that is the same model as your car. Be sure that the region from which you take the license plate is far away from the region in which you live. For example, if your car is a white Camry, look for a white Camry that is far from the region [in which you live], and take its license plate.
"2) Take the car of one of the ordinary people, in some easy way, and carry out the operation that day using [this car]. Then leave the [car] in a public place, so that the infidels will find it and return it to its owners...
"3) After obtaining a suitable car, kill the Crusader, in accordance with the circumstances - if the Crusader works at a company where you work, or at a company where someone you know works, strike him on his day off, or somewhere far from [where the company is located]...; if the Crusader lives next door to you or near you, and you want to kill him, it is best to kill him when he is outside work, so as to distance you from suspicion...
"4) Take care that the windows of the car you use to carry out the [killing] operation are somewhat dark; this will help you when you stop at traffic lights.
"5) When you carry out the [killing] operation and make your escape, travel a route that you have planned in advance. It is best [to go] by the highway for five minutes, and then to move to secondary roads and then to neighborhoods, so as to distance yourself from the place of the operation... [In order to avoid being followed,] look behind you (and check) if anyone is tailing you.
"6) After... [you have evaded being followed] park the car somewhere, [where] you have at your disposal another vehicle, extremely clean, that you will use to return home safely.
"7) Take care not to say a word. The tongue is what will lead you to the infidels' prison. Many brothers have been arrested because they spoke near people.
"It is desirable to film the operation so it can be presented by the media, so that it has a broader impact.
"After the operation succeeds, you will realize that this is very simple, and that there is no need for an entire squad [to carry it out] but that one, two, or three people are enough...
"You can look through the Mu'askar Al-Battar and Sawt Al-Jihad publications, [to learn from them] important things that I may not have clarified here...
