Please, clarify the following points for me:
1- Not cleansing one's traces of urine and “Ghulool” will cause his torment in the grave.
2- Examples of the acts that lead to torment in the grave.3- The meaning of Ghulool and what I should do.

All perfect praise be to Allaah, the Lord of the worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.

In a Hadeeth on the authority of Ibn ‘Abbaas the Prophet once passed by two graves and said that their inmates were being punished. One of them did not use to cleanse himself from urine and the other used to be a tale-bearer. [Al-Bukhari and Muslim] This Hadeeth clearly indicates that neglecting to remove the traces of urine as well as tale bearing cause the person to be punished in the grave.

Ghulool, which refers to taking something illegally from war booty before its distribution, also causes the person who does this to be punished in the grave. The Prophet mentioned that a man who plundered an item from the booty in the battle of Khaybar before its distribution was being punished because of it. [Al-Bukhari and Muslim]

Allaah Knows best.
