LONDON — Health, cleanliness, and hygiene occupy a foundational and extensive place within Islamic teachings. While various historical traditions and nations pursued high spirituality by intentionally neglecting physical self-care and cleanliness, Islam established an entirely different paradigm. In the Islamic tradition, personal hygiene is not merely deemed a good social habit or a matter of cultural preference; rather, it is rendered into active rituals that constitute an essential part of the faith itself.
The integration of cleanliness into daily religious obligations begins with the foundational requirements of worship. A Muslim is required to be in a state of physical purity when performing daily prayers. This spiritual and physical preparation includes proper cleansing after using the toilet and the performance of ritual ablution, known as wudu. Furthermore, under specific circumstances, such as following marital intimacy, a full-body ritual bath, or ghusl, becomes strictly obligatory before a person can resume their ritual prayers.
Beyond these mandatory requirements, Islamic traditions place immense emphasis on finer details of personal hygiene, such as the regular cleaning of the teeth. This meticulous attention to detail stems from a broader worldview concerning human well-being. Islam views the physical human body as an entrusted blessing that must be carefully maintained, ensuring wellbeing in both the earthly life and the hereafter. Within prophetic traditions, a healthy, strong believer is frequently noted as being better and more beloved in the sight of Allah than a weak one, primarily because a healthy individual is far better equipped to fulfill the spiritual and social objectives of Islam and effectively serve humanity.
The following collection of prophetic traditions illustrates the profound stance that Islam takes on matters of health, hygiene, and overall human welfare.

Cleanliness is Part and Parcel of Faith
The foundational connection between physical purity and spiritual devotion is articulated clearly in early Islamic literature. Abu Malik Al-Ash`ari, may Allah be pleased with him, reported that the Messenger of Allah, peace and blessings be upon him, made a concise yet sweeping declaration regarding this principle, stating that purity constitutes half of iman, or faith.
This profound link establishes that the internal state of spiritual belief and the external state of physical cleanliness are deeply intertwined in the daily life of a practicing Muslim. Maintaining purity is not treated as an afterthought, but rather as a direct reflection of one’s inner conviction.
Tooth Brushing is Highly Recommended
Personal oral hygiene receives explicit and repeated encouragement throughout the traditions of the Prophet Muhammad. `A’ishah, may Allah be pleased with her, reported that the Prophet described the miswak—a traditional twig used for cleaning teeth—as an implement that cleanses and purifies the mouth while simultaneously earning the pleasure of the Lord. This narration has been preserved by major traditionists such as An-Nasa’i and Ibn Khuzaimah, and was authenticated by scholars like Al-Albani.
Reinforcing this point, Abu Hurairah, may Allah be pleased with him, reported a statement emphasizing the immense spiritual and physical value placed on oral care. The Messenger of Allah remarked that were it not for the concern of overburdening his followers, he would have made the use of the miswak a mandatory command before every single daily prayer. This statement highlights how deeply the Prophet desired cleanliness to be integrated into the routine habits of the community, stopping just short of making it a strict obligation out of mercy for their daily schedules.

Personal Hygiene is a Human Nature
In addition to ritual purification, Islam recognizes certain grooming practices as fundamental components of the innate human disposition, referred to in Arabic as fitrah. Abu Hurairah reported that the Prophet Muhammad identified five specific practices as integral to this natural disposition: circumcision, shaving the pubic region, clipping the fingernails and toenails, and cutting the moustaches short. By framing these hygiene habits as part of human nature, the tradition underscores that maintaining a neat, well-groomed physical appearance aligns harmoniously with how human beings were naturally created to live.
Rituals on Muslims’ Best Day
The emphasis on personal presentation reaches a weekly peak every Friday, which holds a special status in the Islamic week. Abu Dharr, may Allah be pleased with him, reported a tradition outlining the etiquette and spiritual rewards associated with the congregational Friday gathering.
According to the narration, whoever takes a thorough bath on a Friday, purifies themselves meticulously, puts on their best available clothing, applies whatever family perfume is accessible, and then proceeds to the mosque without engaging in idle talk or disrupting others by pushing between people will receive a profound spiritual reward. The tradition notes that such a person will have their sins forgiven for the span between that day and the previous Friday, bridging community gathering with deep spiritual renewal and physical presentation.
Keep Environment Clean
Islamic teachings on hygiene extend far beyond the individual body to encompass the preservation of public spaces and the natural environment. Mu`adh, may Allah be pleased with him, reported a stern warning from the Prophet regarding actions that pollute shared spaces and invite community distress. The Prophet warned against three specific acts that bring negative consequences: relieving oneself in shaded places utilized by the public, along pathways where people walk, or directly beside water sources where people gather.

Complementing this prohibition on public pollution is a strong emphasis on active civic responsibility. Abu Dharr Al-Ghafari reported that the Prophet Muhammad explicitly stated that the simple act of removing harmful objects and obstructions from a road or pathway is counted as an act of charity, or sadaqah. This teaching places environmental stewardship and public safety directly within the framework of moral and charitable deeds.
Using Medicine is Encouraged
The holistic approach of Islam toward health includes a pragmatic and proactive attitude toward modern and traditional medical treatment. Usamah ibn Sharik narrated an incident where he came to the Prophet, finding his Companions sitting in such profound quietude that it seemed as though birds were perched atop their heads. After greeting them and taking a seat, various desert Arabs arrived and posed a direct question to the Messenger of Allah, asking whether they should make use of medical treatment for their ailments.
The Prophet responded with an unequivocal affirmation, advising them to make full use of medical treatment. He explained that Allah has not created any disease on earth without simultaneously appointing a remedy and cure for it, with the sole exception of a single natural condition, which is old age. This perspective removes any fatalistic hesitation regarding healthcare, encouraging believers to actively seek professional medical help when facing illness.
Be Strong and Healthy
The overarching philosophy regarding physical capability and mental resilience is encapsulated in another narration by Abu Hurairah. The Messenger of Allah stated that a strong believer is inherently better and more beloved to Allah than a weak one, while noting that goodness exists in both.

The Prophet further advised his followers to keenly pursue whatever benefits them in life, to seek help exclusively from Allah, and to never give in to despair or surrender to helplessness. He cautioned against falling into cycles of regret, instructing that if an adverse event or hardship befalls a person, they should avoid dwelling on counterfactual thoughts starting with "if only." Instead, believers are encouraged to recognize that everything occurs according to the decree and will of God, as dwelling on such regrets merely opens doors to negative, unproductive thoughts.
Overeating is Not Healthy
Dietary moderation is treated as a crucial pillar of physical wellness and preventive health in Islamic guidance. Al-Miqdam narrated that the Prophet Muhammad delivered a clear guideline regarding portion control and the dangers of excessive consumption.
The Prophet observed that a human being fills no container worse than his own stomach. He explained that a few small morsels capable of keeping a person’s back upright and sustaining their energy are entirely sufficient. However, if a person chooses to eat more than the bare minimum, they should divide their stomach capacity into three distinct portions: one-third allocated for food, one-third for liquids, and the final third left empty to facilitate comfortable breathing and digestion. Through these detailed directives, Islamic teachings consistently promote a balanced, mindful, and health-conscious lifestyle across all aspects of daily living.
