Al-Kāfi 2, narration 123

Translation

6. A number of our people have narrated from Ahmad ibn Muhammad ibn Khalid from Ahmad ibn Muhammad ibn abu Nasr from Safwan al-Jammal who has said the following: “Once I asked Abu ‘Abdillah (a.s.) about the words of Allah, the Most Majestic, the Most Holy: ‘The tumbling wall belonged to two orphans in the town whose father has been a righteous person. Underneath the wall there was a treasure that belonged to them.’ (18:82) “The Imam said, ‘It is a fact that the treasure did not consist of gold and silver. It consisted of four sentences: “No one deserves to be worshipped except I (Allah). Whoever has realized with certainty that death is inevitable has enough reason not to laugh for a year. Whoever has realized with certainty that accountability on the Day of Judgment is true has enough reason for his heart not to rest in ease. Whoever has realized with certainty that Allah does everything with strict measurements has enough reason not to fear anyone except Allah.’””
