He (s.a.w.s.) said...
He (s.a.w.s.) said, “Does not this one have what his hair needs?”13 And it was also reported from him (s.a.w.s.) this saying when he saw another man with dirty clothes, “Does not this one have water to wash his clothes?”14 Surely, the Islamic thought and civilization is far above others, when it emphasizes that the Almighty Allah wants for His servant a pleasant life and purity, and environment which is not polluted.
The Holy Prophet (s.a.w.s.) elaborated on this point saying, “Surely Allah is good and He likes goodness; He is Pure and He likes purity.”15 And while talking about Islam’s purity and cleanliness and its call toward environmental sanitation, Holy Prophet (s.a.w.s.) says, “Surely, Islam is pure, therefore be pure, because he can never enter Paradise who is not pure.”16 Prohibiting environmental pollution: As Islam exhorts it followers toward purification, likewise, it prohibits environmental pollution and destruction.
On this matter, it was reported from the Holy Prophet (s.a.w.s.) that he prohibited spitting on the earth, because of its harmful effects on the health, and its contradiction to human nature. However, as the Holy Prophet (s.a.w.s.) prohibits spitting, he also prohibits and warns against defecating under a fruit tree and urinating in stationary or flowing water and also, on the road, so as to protect the environment from pollution and, also, as a protection to health and purity.
We can outline the importance of this advice if we understand the danger of human waste products to our health and to the environment, especially the role which these contaminates of water play in spreading diseases to the community through drinking, bathing and the fruits which are watered by this water.
