3-64 Abul Abbas Muhammad ibn Ibrahim ibn Ishaq al-Taleqani - may God be pleased with him - narrated that Muhammad ibn Jarir al-Tabary quoted Abu Salih al-Kanani, on the authority of Yahya ibn Abdul Hamid al-Himmani, on the authority of Sharik that Hosham ibn Mu’az said that once he was accompanying the Caliph Umar ibn Abdul-Aziz on a journey to Medina. Then it was announced that whoever has been oppressed can come to see the Caliph. Muhammad ibn Ali al-Baqir (MGB) went there. The Caliph was told by his gate-keeper Mozahim that Muhammad ibn Ali al-Baqir (MGB) has come to see him. Umar ibn Abdul-Aziz said, “O Mozahim. Please let him in.” Mozahim asked the Imam to enter while Umar was wiping off his tears. Muhammad ibn Ali al-Baqir (MGB) asked Umar, “O Umar! Why are you crying?”Then Hosham (ibn Ma’az) said, “O grandson of the Prophet of God! Such and such are the reasons why he is crying.”Then Muhammad ibn Ali al-Baqir (MGB) said, “O Umar! Indeed this world is only like a shop in a supermarket. Some people take things from it due to which they suffer a loss. Others take things from it from which they benefit. There are many people who engage themselves in things similar to what we engage in until their time of death arrived and they suffered from a great loss. They left this world in a state of being sorry since they had not hesitated to do bad deeds and had not taken anything for their Hereafter. Those who would not be grateful divided up all the inheritance which they had left behind in this world, but they had to go to Him who would not accept any excuses! It would be advisable to review the affairs of this world and avoid doing wicked deeds. Fear God and be determined to do two things. First try to take some good deeds with you which would be with you when you face your Lord. Secondly, abstain from evil deeds and do not takewith you something which will cause you to be sorry when you face your Lord. O Umar! Fear God the Honorable the Exalted! Open the door and raise the curtain (to let the people in to see you). Assist the oppressed ones and defeat the oppressors.”Then the Imam (MGB) added, “There are three things which would perfect one’s belief in God.”Once Umar heard this, he sat down on his knees and asked, “O Member of the Holy Household of the Prophet! What are they?”The Imam (MGB) said, “Yes, Umar! That is that once you are pleased, your pleasure doesn’t cause you to engage in wrongful deeds. Also once you are angry, your anger would not lead you to do what is not rightful, and once you are powerful, you do not devour what is not yours.”Then Umar asked for ink and a quill and wrote, ‘In the Name of God the Compassionate the Merciful. I - Muhammad ibn Abdul-Aziz - hereby return the tract of land called Fadak which belongs to Muhammad ibn Ali al-Baqir (MGB).’”
