(11) باب الاِسْتِبْرَاءِ مِنَ الْبَوْلِ
Narrated Ibn 'Abbas :
The Prophet (sal Allaahu alayhi wa sallam ) passed by two graves. He said : Both (the dead) are being punished, but they are not being punished for a major (sin). One did not safeguard himself from urine. The other carriedtales. He then called for a fresh twig and split it into two parts and planted one part on each grave and said: Perhaps their punishment may be mitigated as long as the twigs remain fresh.Another version of Hannad has: "One of them did not cover himself while urinating." This version does not have the words: "He did not safeguard himself from urine."
