The Muslim should respect the mosques and keep them free of dirt and impurities, and anything that is not appropriate. In this hadith, Anas ibn Malik (may Allah be pleased with him) narrates that the Prophet (blessings and peace of Allah be upon him) saw sputum in the qiblah of the mosque. Sputum refers to what is ejected from the mouth or nose of spittle, mucus and the like. The Prophet (blessings and peace of Allah be upon him) was upset by that and got so angry that his anger could be seen in his face. He got up and scratched it with his hand, to remove it and clean it, then he said: “When one of you stands in prayer, he is conversing with his Lord” – the root meaning of the word translated here as conversing refers to private talk between two people. What is meant is that he should observe proper etiquette in this situation, because the worshipper is conversing with Allah (may He be glorified and exalted). Then he forbade any Muslim to spit in the direction of his qiblah, because spitting is usually a sign of disrespect, so it is not appropriate to the high esteem in which the direction of the qiblah is held. But if he must spit whilst he is in the mosque, let him spit to his left, for that is the direction for such dirty things, or beneath his feet, so that he may cover it with his foot in the earthen floor. Then the Prophet (blessings and peace of Allah be upon him) took the edge of his rida’ [upper garment], spat on to it, then folded part of it over another part and said: “Or let him do like this.” Thus he explained by his actions, so that the listener would understand better, and also to make it clear to the one who would not be able to bury his sputum. Spitting in the mosque is a sin, because it is indicative of disrespect towards the houses of Allah (may He be glorified in exalted) which He has commanded are to be built and His name mentioned therein. Moreover, it is offensive to other worshippers. A worshipper may prostrate on it without realizing, and he may be disgusted if he sees it and find it repugnant. This hadith highlights the true nature of ihsan, which refers to a person constantly bearing in mind how close Allah (may He be exalted) is to him, that Allah is watching him and that He knows all about him. It is also refers to honouring and respecting the qiblah, and highlights the superiority of the right over the left. It also indicates that sputum is pure (tahir). .
