Why is it that one pushes back a passerby in front of the one who is praying, when he has already fulfilled the obligation of placing a barrier in front of him; so this passerby does not harm him?

The Shaykh : The questioner asks: Why is it that one pushes back a passerby in front of the one who is praying, when he has already fulfilled the obligation of placing a barrier in front of him; so this passerby does not harm him?
We say: This question is incorrect; for it is not befitting for a Muslim to say: Why did Allah say such and such? Why did the Messenger of Allah say such and such? Because this contradicts the stance that every Muslim must adopt before the Book of Allah and the Hadith of the Messenger of Allah. We all know, and especially the questioner, the saying of Allah (Mighty and Majestic): . So the question is: Why? And I will tell you simply: Because the Messenger said this. So what is the meaning of the question? Perhaps the meaning of the question—and here is the correction of the question—is: What is the wisdom? Asking about the wisdom is one thing, and asking why the passerby in front of the one who is praying is pushed back is another; for the answer to the question "Why is he pushed back?" is: Because the Messenger said: . This is the answer.
And I believe the questioner knows this; so he is asking about the wisdom, I suppose. If he means asking about the wisdom, then I say simply and frankly: In matters of worship, we do not strain ourselves to ask about the wisdom of their legislation. If a wisdom appears to us in this simple way, without any strain, we mention it; otherwise, we do not delve deep. For delving deep, in my belief and in my long experience in calling people to act according to the Book and the Sunnah, for opening the door to seeking the wisdoms of legislation leads those accustomed to such questions to have their religious restraint weakened: ; because he becomes accustomed to knowing the wisdom of every command. If he does not know the wisdom, he remains questioning, or rather, he remains doubtful: What is this? And what is the secret? And what is the purpose? My brother, and that is enough. If you have knowledge, no one can present a wisdom to you; so there is no harm in that, but the principle is submission.
