When you want to urinate or defecate then don't do it in any place, especially in public places where people usually move. Because it may be that the dirt can be stepped on or occupied by other people which causes other people to issue swear words for people who defecate carelessly. Therefore, when you want to urinate and defecate, look for a toilet.

There are three places that a person is not allowed to defecate or defecate. This is as the book at Targhib wa Tarhib writes a hadith of the Prophet Muhammad narrated by Ahmad.

وَقَالَ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : اِتَّقُوالْمَلَاعِنَ الثَّلَاثَ قِيْلَ مَا الْمَلَا عِنُ الثَّلَاثُ يَارَسُوْلَ اللَّهِ؟ قَالَ  : أَنْ يَقْعُدَأَحَدُكُمْ فِى ظِلٍّ يَسْتَظِلُّ بِهِ أَوْفِى طَرِيْقٍ أَوْفِى نَقْعِ مَاءٍ.

Prophet Muhammad said: Avoid three things that can bring curse. The Messenger of Allah asked: What are the three things that bring curses, O Messenger of Allah? The Prophet said: Defeat one of you in a shady place where people will take shelter in that place, or defecate on the street, or defecate in a puddle.

From the hadith it can be understood that never urinate or defecate in places that are often used by people for shelter. For example under a tree or even at a bus stop. Because other people will step on or even sit on their feces and make them angry or even utter words that curse people who defecate.

Likewise, never urinate or defecate on a street where people often pass by. Because maybe someone else stepped on the dirt and carried it to the house or place of work. And don't urinate or defecate in puddles of water, for example in water reservoirs where water is often used by the community.
