It is permissible to pray wearing sandals, so as to make things easier for the Muslim ummah, and also to be different from the Jews. In this hadith, the Tabi‘i Abu Maslamah Sa‘id ibn Yazid narrates that he asked Anas ibn Malik (may Allah be pleased with him), the servant of the Prophet (blessings and peace of Allah be upon him): Did the Prophet (blessings and peace of Allah be upon him) pray wearing his sandals on his feet, in any prayer, whether it was supererogatory or obligatory? Anas replied in the affirmative, and said that the Prophet (blessings and peace of Allah be upon him) indeed did that, and this was a concession to make things easier for the ummah. Moreover, it is narrated in Sunan Abi Dawud from the Prophet (blessings and peace of Allah be upon him) that he said: “Be different from the Jews, for they do not pray in sandals or khuffs.” What appears to be the case is that this is for the purpose of being different from the Jews. The word translated here as sandals refers to footwear that is worn to protect the feet from the ground when walking. The reports explain that when wearing sandals, it is stipulated that they should be pure (tahir) and free of any impurities (najasah). Whoever finds anything (najasah) on his sandals should rub them with dust, to purify them. This hadith highlights the keenness of the Sahabah and Tabi‘in to follow the Sunnah of the Prophet (blessings and peace of Allah be upon him). .
