4. A number of our people have narrated from Sahl ibn Ziyad from Muhammad ibn Sinan from Ishaq ibn ‘Ammar from abu al-Hassan (a.s.), who has said the following
“I asked the Imam (a.s.), ‘Does a believing deceased notice who has visited his grave?’ He replied, ‘Yes, and he continues to take comfort in his visitor as long as he is near his grave. When the visitor stands up and leaves the gravesite he (the deceased) becomes afraid and lonely.’”
