What is the wisdom behind Muslims turning towards the Kaaba in their prayers, even though they do not worship it?

The reason Muslims face the Kaaba in their prayers is to obey Allah's command, without seeking to understand the wisdom behind it. This is a form of divine test for believers, distinguishing the truthful from the false. This meaning is clear in the words of Umar ibn al-Khattab, may Allah be pleased with him, to the Black Stone: "By Allah, I know that you are a stone that neither harms nor benefits, and had I not seen the Messenger of Allah kissing you, I would not have kissed you." Muslims pray Dhuhr four rak'ahs, Maghrib three, and Fajr two, and they circumambulate the House seven times, and stone the pillars seven times; all of this is because Allah commanded them to do so. Whoever comprehends these meanings will increase in his servitude to Allah, draw closer to his Lord, and find delight, happiness, and comfort. As for one who resists and refuses to act until he understands, he resembles Iblis. Belief in the unseen is one of the characteristics of believers, as stated in the Almighty's saying: ﴿That is the Book, in which there is no doubt, a guidance for the righteous. Those who believe in the unseen, establish prayer, and spend from what We have provided for them.﴾ Our prayers towards the Kaaba are not related to its construction, but to its location. So, if it were demolished, prayer would still be directed towards its direction. This differs from the actions of the polytheists, whose worship of their idols ceases when the idols cease to exist.
