WHY WAS MUHAMMAD WEARING SHOES IN THE MOSQUE?

The Messenger of Allaah (peace and blessings of Allaah be upon him) said, ‘Jibreel (peace be upon him) came to me and told me that there was something dirty on them.’ When any one of you comes to the mosque, let him look and if he sees anything dirty on his shoes, let him wipe them and then pray in them.” (Abu Dawood, 650; classed as saheeh by al-Albaani in Saheeh Abi Dawood, 605). 

The Prophet said: “If one of you comes to the masjid, he should look at the bottom of his shoes. If he sees any impurity on them, he should rub them on the ground. Then he may enter with them (i.e, the shoes) and pray with them on.”

Anas ibn Maalik (may Allaah be pleased with him) was asked, “Did the Prophet (peace and blessings of Allaah be upon him) pray wearing shoes?” He said, “Yes.” (al-Bukhaari, 386; Muslim, 555). 

“Be different from the Jews, who do not pray in their shoes or in their leather slippers (khufoof).” (Abu Dawood, 652; classed as saheeh by al-Albaani in Saheeh Abi Dawood, 607).
