Mafhum-e-Hadith : Qabr ka Azab (Torment of the grave)
Ibn Abbas Radhi Allahu Anhuma se rivayat hai ki Rasool-Allah Sal-Allahu Alaihi Wasallam do Qabron ke pass se guzre aur farmaya ki in dono qabron ke murdon par azab ho raha hai aur ye kisi bade gunaah ki wajah se azab mein giraftar nahi hain bulki ismein se ek peshaab ke cheenton se nahi bachta tha aur ye (dusra) chugalkhor (backbiter) tha phir aapne ek hari shaakh mangwayee aur use Do tukdon mein faad kar dono qabron par laga di iske bad farmaya ki jab tak ye shaakhein sukh na jayegi us waqt tak shayad in dono ka azab halka rahey.
Sahih Bukhari, Vol 7, 6052
Narrated Ibn ‘Abbas Radhi Allahu Anhuma: ALLAH’s Apostle Sal-Allahu Alaihi Wasallam passed by two graves and said, “Both of them (persons in the grave) are being tortured, and the are not being tortured for a major sin. This one used not to save himself from being soiled with his urine, and the other used to go about with calumnies ( backbiting). The Prophet then asked for a green leaf of a date-palm tree, split it into two pieces and planted one on each grave and said, “It is hoped that their punishment may be abated till those two pieces of the leaf get dried.
