What is the ruling on taking a sandal in place of one’s lost sandal from the mosque door?

The Shaykh : Now let us return to the questions. Among the questions is one asked by a brother, which relates to the lesson. The sandals that are at the door of the Haram: a person might bring his sandals and leave them there, but when he leaves the mosque, he does not find them; however, he finds others. Is he allowed to take the others in place of his own? The answer is no. He should not take them, because it is possible that someone stole his sandals, and these remaining sandals belong to their owner in the mosque. Now, consider a person in a mosque other than the Haram. The people leave the mosque, and he had left his sandals at the door. When he leaves the mosque, he finds that his sandals have been taken and only one sandal remains. Does he take it or not?
Do you understand this situation or not? This happens sometimes. A person remains in the mosque while the others leave, and only this man is left. He had placed his sandals at the door. When he leaves, he does not find his sandals, but finds other sandals in their place. Does he take this sandal and say, “The owner of this sandal took my sandals by mistake and left his own,” or does he not? Yes. No, in a place other than the Haram.
Now, if there is a possibility of mistake, such that the remaining sandal resembles his own, it appears that its owner made a mistake, so he takes this sandal. But if the remaining sandal is better than his own, meaning it is new and his is old, what does he do? It is difficult. Yes, we say he takes it and pays the difference, giving it as charity. One sandal is worth five riyals and this one is worth ten riyals; he pays the difference.
Nevertheless, I say the more cautious course is to leave it, because sometimes a person is in a hurry and puts on someone else’s sandals and does not remember until he reaches home, for example. Then he returns to the place to look for his sandals. So the precaution is to leave it until the next prayer, in case its owner comes. Go to them and ask them. Yes. Now, now I am asking you. If you are accused of this suggestion, as long as you have a question, we do not accept it. Yes, yes, later we accept it, right? Right? Not good, do you have two of them? Let them record it so they can go home. This one objects, but are you convinced now?
