It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) said: "Beware of the two things that bring about curses," or he said: "Beware of the two things that cause people to curse." (That is, because of which people curse.) It was asked, "What are those two things?" The Prophet (peace and blessings of Allah be upon him) said: "The person who relieves himself in people's pathways or in places where they seek shade." Imam Abu Bakr (may Allah have mercy on him) says: «‏‏‏‏او ظلهم» ‏‏‏‏ "From among their shaded places," by this the Prophet (peace and blessings of Allah be upon him) meant those shaded places where people gather to benefit from the shade. I have deduced this from the hadith of Sayyiduna Abdullah bin Ja'far (may Allah be pleased with them both), that the Prophet (peace and blessings of Allah be upon him) liked to conceal himself for relieving himself behind an elevated place (such as a wall or a mound) or behind a cluster of date palms. Because by "hadaf" is meant a wall, and by "cluster of date palms" is meant a group of date trees. A garden is called a "cluster" (jhund) because of the abundance of trees. The shadow of a wall remains at all times except when the sun is at its zenith, while the shadow of a cluster of date palms remains all day (that is, even at the time of zenith its shadow remains). And the Prophet (peace and blessings of Allah be upon him) used to like that a person should conceal himself for relieving himself behind a wall or a cluster, even if both have shade.
