Mosques are the Houses of Allah on earth, and they must be kept free from all filth and impurity. The Prophet (peace and blessings of Allah be upon him) clarified what is permissible to do in the mosques and what is prohibited. Eating and drinking in the mosque are among the actions that are permitted and not objectionable, as indicated in the following Hadith: Narrated by `Abdullah ibn Al-Harith ibn Juzʾ Az-Zubaidi (may Allah be pleased with him): “We used to eat bread and meat in the mosque during the time of the Messenger of Allah (peace and blessings of Allah be upon him).” This indicates that they used to eat in the mosque, and the Prophet (peace and blessings of Allah be upon him) was aware of this and approved it; he did not prohibit it. There are many Hadiths that support this meaning—among them is the residence of Ahl As-Suffah (the poor Companions) in the mosque, which necessarily entailed that they ate there. The Companions (may Allah be pleased with them) used to hang bunches of dates in the Prophet’s Mosque for the needy to eat. However, excluded from this are foods that have been prohibited in the mosque, such as onions, garlic, leeks, and everything that has a strong odor, for the angels are harmed by what harms the children of Adam. One must observe the etiquette of eating and drinking in the mosque, and refrain from defiling the mosque with food remnants or anything that may cause harm to the worshippers.The Hadith affirms the permissibility of eating and drinking in mosques, provided that the Shari`ah guidelines are upheld to safeguard the sanctity of these sacred spaces..
