There are people at work or in any place outside the mosque who pray while wearing their shoes; what is the ruling on that?

Question:
He says: There are some people, whether at work or in any place outside the mosque, who pray while wearing their shoes. What is the ruling on that? Is it permissible or not? May Allah reward you with good.

Answer:
Praying in sandals is a recommended practice (sunnah), so there is no blame on one who does so, provided the sandals are pure. One should check them when entering the mosque. If they are clean and free from ritual impurity, he prays in them, because the Prophet (peace and blessings be upon him) said, "Pray in your sandals and differ from the Jews." Once, the Prophet (peace and blessings be upon him) was praying and took off his sandals during the prayer, so the Companions took off their sandals. When he finished the prayer and said the closing salam, he informed them that he had only taken them off because Jibril told him there was impurity in them. Therefore, praying in sandals is a recommended practice (sunnah), unless this practice leads to harm, such as soiling the mosque. This is especially true now that the condition of mosques has changed in this era; they are paved with tiles and covered with carpets. There is no doubt that entering with sandals affects them. In that case, it is better to pray without sandals to avoid the soiling of the mosque. As for the mosques in the time of the Prophet (peace and blessings be upon him) and until recently, they were covered with sand and gravel, so they were not affected by sandals. But now the situation has changed in many mosques, especially in cities where they are carpeted. There is no doubt that entering with sandals affects the carpets, causing them to become damaged and soiled with dust. Yes.
