Abu Hurairah (May Allah be pleased with him) said:
The Messenger of Allah (ﷺ) said, "Avoid two habits which provoke cursing." The Companions said: "What are those things which provoke cursing?" He said, "Relieving on the thoroughfares or under the shades where people take shelter and rest."[Muslim].
