Riyad as-Salihin, Book 18, Hadith 1771 (In-Book) ⓘ
Abu Hurairah (May Allah be pleased with him) said: The Messenger of Allah 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 صلى الله عليه وسلم قال: “اتقوا اللاعنين” قالوا: وما اللاعنان؟ قال: "الذي يتخلى في طريق الناس أو في ظلهم" ((رواه مسلم)).
