“I was in the presence of my father during the day in which he passes away. He made several recommendations to me about his funeral matters, such as washing his whole body, shrouding him and placing him in his grave. I then said to him, “Father, I have not seen in a better health from the day you complained illness than today. I do not see in you any sign of death.” The Imam (a.s.) said, “Son, have you not heard about Ali ibn al-Husayn (a.s.) calling from behind the wall, ‘O Muhammad, come. Be quick.’”
