“Abu ‘Abd Allah (a.s.), has said that a deceased is asked in his grave about five issues. He is asked about his prayer, Zakat (paying charity), his Hajj, his fasting and about our, Ahl al-Bayt’s wilayah (guardianship) over him. Wilayah then from one side of the grave says to the others, ‘If you face any deficiency in your task (of protecting him), leave it for me to suffice?”
