From Sahih Muslim (Hadith 618):
Abu Huraira reported:The Messenger of Allah (ﷺ) 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 they take shelter and rest)
