Jabir (May Allah be pleased with him) said: The Messenger of Allah peace be upon him forbade urinating into stagnant water.
وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، وَمُحَمَّدُ بْنُ رُمْحٍ، قَالاَ أَخْبَرَنَا اللَّيْثُ، ح وَحَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا اللَّيْثُ، عَنْ أَبِي الزُّبَيْرِ، عَنْ جَابِرٍ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم أَنَّهُ نَهَى أَنْ يُبَالَ فِي الْمَاءِ الرَّاكِدِ .
[Sahih Muslim 281].
Respected Brothers and Sisters:
“Stagnant water” means water, which is not flowing, like the water in a pond or a tank. When urination is prohibited at such places, defecating would be more sternly prohibited. One must also avoid throwing filth in it.
How vast and comprehensive the injunctions of Islam are, and how thoroughly Islam has grasped the problems of people, is something unique in the realm of religion. No other world religion can match it in this respect.
It is very unfortunate indeed that in spite of having such perfect and complete religion, the Muslims are far away from practicing its noble teachings. May Allah enable us to become true followers of Islam. Ameen
Allah knows Best.
