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].

وعن أبي هريرة رضي الله عنه أن رسول الله ﷺ قال: “اتقوا اللاعنين” قالوا: وما اللاعنان؟ قال: "الذي يتخلى في طريق الناس أو في ظلهم" ((رواه مسلم)).
