Be on your guard against two things which provoke cursing
Abu Huraira (may Allah be pleased with him) reported:
The Messenger of Allah (may the peace and blessings of Allah be upon him) said: Be on your guard against two things which provoke cursing. They (the companions present there) said: Messenger of Allah, what are those things which provoke cursing? He said: Easing on the thoroughfares or under the shades (where people take shelter and rest).
Islam calls for cleanliness and refrainment from all that which contradicts the sound nature, or cause harm to people. The purity is half of faith and cleanliness is a proof of the integrity of nature the refrainment from all that which bring blame indicates adopting the virtuous manners and noble behaviors.
His words, may the peace and blessings of Allah be upon him, Be on your guard against two things which provoke cursing. Is an eloquent manner that the hearer needs to understand and meditate. Then he explained these two things to be avoided;
That is, to urinate or to defecate in the public road and in the places where people used to sit, where the shadow is spread - under the trees - or under the walls - and so on.
Just as it is not permissible to answer the call of nature in the way of people, it is not permissible to throw stones, shuck, and other dirts, or to put obstructions that stand in the way of people and deprive them of rest.
This is reflected in the high voices in the gatherings, roads, houses, mosques and others, and verbal abuse from which the people of modesty and virility feel shy.
The Islamic legislation return people to the sound nature and eliminates all customs that are incompatible with this normal nature.
Those who know and adhere to this legislation have avoided every act that defies modesty or contradicts the proper manners.
