Is it permissible for him to spread something in the mosque to pray in it when he arrives?

Question : If he spreads a place, is it permissible for him to come and pray in it? I mean, is it permissible for him to spread something in a place to pray in it when he arrives?

Answer : The school of thought holds that this is permissible. It is not permissible for anyone else to sit in it. Because this prayer spot belongs to whom? To the one who spread it. It is not permissible for him to pray on it and dispose of another person's property. But is it permissible for another person to remove it?
He says: Leave it. There are two views on this. The first view is that he has the right to remove it because he placed it there without right. The second view is that he does not have the right to remove it. The school of thought holds that he does not have the right to remove it except when the prayer is called for. There is no doubt that if he removes it, there will be a dispute, quarrel, and enmity between him and its owner, and each will look at the other with anger. Repelling harms is more important than seeking benefits. However, this man who places a prayer mat or other item to reserve it from the people, who are more deserving of it than he is, should be advised. It should be said to him: "My brother, do not do this, because if you do, you deprive others of the empty space. And if you do it, you rely on the fact that you have secured a place for yourself in the front of the mosque, so you become lax in arriving early and moving forward, as is the case now. People observe that those who are unable to get the front rows do not come until the very end, because he sees that he has guaranteed himself a place in the first row, so he delays. However, if he leaves his seat for an excuse and then returns, he has the right to his place, and he has the right to remove whoever sat in it. But he should place something in his place when he leaves for an excuse to indicate that he will return, so that no one sits in it and a dispute arises when he returns and says, "Get off my place." And whatever prevents quarreling among Muslims is good.
