9. Ali has narrated from his father from Ja’far ibn Muhammad al-Ash’ari from ‘Abd Allah ibn Maymun from Abu ‘Abdillah عليه السلام who has said the following: “Once Amir al-Mu’minin (Ali ibn abu Talib) عليه السلام entered the Mosque and at the door of the Mosque he met a man who was depressed and sad. Amir al- Mu’minin (Ali ibn abu Talib) عليه السلام asked him ‘What has happened to you?’ He said, ‘It is due to the death of my father, mother and brother. O Amir al- Mu’minin, I am afraid my gall bladder may have ruptured.’ Amir al-Mu’minin (Ali ibn abu Talib) عليه السلام said, ‘You must be pious before Allah and exercise patience. Tomorrow (on the Day of Judgment) you will proceed to Him. Patience in the issues (in life) is like a head to a body. If the head departs the body is destroyed, likewise, in the issues (of life), if patience departs the issues, all affairs (of life) are destroyed.”’
