Is 'Umar's preparation of the army an example of obsessive thoughts in prayer, and can scholarly issues be analogized to it?

The questioner : ... just as 'Umar used to prepare the army.

The Shaykh : No, 'Umar's action is commanded, and it is not an action of obsessive thoughts. For this reason, in the prayer of fear, the prayer itself was changed for the sake of the benefit of jihad. This is part of the benefit of jihad. The issue of knowledge is not analogized to it. If you begin your prayer and start thinking about a jurisprudential issue, saying so-and-so said this and so-and-so said that, and then you think about grammatical issues, and you say that these are among the supporting and assisting means, and then you come to look into mathematical issues and say that this is beneficial for the science of inheritance, you cannot do that. But jihad is necessary, so one thinks about it now; one needs to think about this.

The questioner : Is this for the imam or for others?

The Shaykh : Everyone who has an interest in the expedition, even if not the imam, may have a thought occur to him that was not on the imam's mind.
