10. A number of our people have narrated from Sahl ibn Ziyad from ‘Abd al-Rahman ibn abu Najran from ‘Asem ibn Humayd from abu Basir who has said the following: ”1 heard abu ‘Abd Allah (a.s.), say, ‘When a person is placed in his grave, two angels come to him, one from the right, the other from the left, and Satan whose eyes are made of brass stands before his eyes. The two angels will ask, “What do you say about the man who lived among you?’” The Imam then said, ‘This causes him a terrifying alarm. If a believing person, he says, “Are you asking about Muhammad, the Messenger of Allah?” The two angels will then say to him, “Rest to sleep without dreams therein.” They will make his grave spacious by nine yards. He then observes his seat in paradise.’ This is what Allah, the Most Majestic, the Most Glorious, has mentioned (in His Book), ‘Allah keeps the believers steadfast upon the firmly established word both in this and in the next life.’ (14:26) If he is an unbeliever, the two angels will ask, “Who is the man who appeared among you?” He will say, “I do not know.” The two angels will then leave him with Satan.’”

11. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from Ibrahim ibn abu al-Balad from certain persons of his people who has said the following: “Abu al-Hassan Musa (a.s.), has said, that a believing person in his grave will be asked, ‘Who is your Lord?’ He will reply, ‘Allah is my Lord.’ He is then asked, ‘What is your religion?’ He will reply, ‘Islam is my religion.’ He is then asked, ‘Who is your prophet?’ He will reply, ‘Muhammad is my prophet.’ He is then asked, ‘Who is your Imam?’ He will reply, ‘So and so is my Imam.’ He is asked, ‘How did you come to know that he is your Imam?’ He will reply, ‘It is a matter to which Allah guided me and kept me steadfast therewith.’ It then will be said to him, ‘Rest to sleep without dreams like the sleep of newly wedded person.’ A door to paradise is then opened to him through which fragrance and happiness of paradise continue to come to him. He will then say, ‘Lord, allow the Day of judgment to come quicker so I can return to my family and property.’ An unbeliever is asked, ‘Who is your Lord?’ He replies, ‘Allah is my Lord.’ He is then asked, ‘Who is your prophet?’ He replies, ‘Muhammad is my prophet.’ He is then asked, ‘What is your religion?’ He replies, ‘Islam is my religion.’ He is then asked, ‘How did you come to know it?’ He replies, ‘People said so and so did I.’ The two angels will then strike him with a war-club on his head such that even all man and Jinn together cannot bear (its pain). The Imam then said, ‘He will melt like lead. Then they will return his soul to his body and place his heart between two boards of fire and he will plead, “O Lord, please delay the coming of the Day of Judgment.’””
