The Prophet (blessings and peace of Allah be upon him) was the best of people in attitude and in raising his companions’ spirits. Every time he visited them, he would teach them some rulings and etiquette, and the Sahabah transmitted his teachings and his Sunnah to the ummah so that they could learn the rulings of Islam from it. In this hadith, Anas (may Allah be pleased with him) narrates that his grandmother Mulaykah, who was his maternal grandmother, invited the Messenger of Allah (blessings and peace of Allah be upon him) to a meal that she had made for him, and he accepted her invitation and ate some of that food. The Sahabah (may Allah be pleased with him) would invite him to their houses, so that he could lead them in prayer and they could receive his blessing. Then after the meal ended, he instructed them to get up and pray so that he could teach them how to pray in a practical manner, or to bless the place for them by praying in it and offering supplication for them. So Anas (may Allah be pleased with him) got up to fetch an old mat that had turned black from long use. He sprinkled it with water, to clean it, soften it and prepare it for people to sit on it, or to remove any uncertainty as to whether it was impure (najis). Then the Prophet (blessings and peace of Allah be upon him) stood up, and Anas and the orphan – who was Damrah or Dumayrah ibn Sa‘d al-Himyari, or someone else, and he had reached the age of discernment – stood behind him, in one row, and his grandmother Mulaykah stood behind them, because the women stand behind the men and children in the prayer. Then the Prophet (blessings and peace of Allah be upon him) led them in praying two rak‘ahs, then he left after he prayed. This is part of Prophetic etiquette, to make one’s visit brief, to leave after having fulfilled the purpose of one’s visit, and to offer supplication for the people who live there. This hadith indicates that it is permissible for the worshipper to prostrate on a carpet or rug to keep his face from touching the ground directly. .
