Narrated Ibn `Abbas:The Prophet (ﷺ) once passed by two graves and said, "They (the deceased persons in those graves) are being tortured not for a great thing to avoid." And then added, "Yes, (they are being punished for a big sin), for one of them used to go about with calumnies while the other never saved himself from being soiled with his urine." (Ibn `Abbas added): Then he took a green leaf of a date-palm) and split it into two pieces and fixed one piece on each grave and said, "May their punishment be abated till these (two pieces) get dry
Ibn Abbas (رضی اللہ عنہما) bataate hain: Nabi ek baar do qabron ke paas se guzre aur farmaya: "Yeh (marhoom) kisi badi cheez (se bachne mein kotahi) ke liye azaab nahi paa rahe." Phir joda: "Haan, (unhe kisi bade gunah ki saza mil rahi hai), kyunke ek chughli khataa tha, aur doosra kabhi apne peshab se khud ko nahi bachata tha." (Ibn Abbas ne joda:) Phir Aap ne khajoor ka ek hara patta liya, use do tukdon mein baanta aur har qabar par ek tukda gaad diya, aur kaha: "Shayad unka azaab kam ho jaaye jab tak yeh (patte) sukh na jaayein."
