2-78- B It was narrated by Muhammad ibn Ali al-Bishari al-Qazvini - may God be pleased with him - that Al-Muzaf’far ibn Ahmad al-Qazvini quoted Muhammad ibn Ja’far al-Kufy Al-Asady, on the authority of Muhammad ibn Isma’il al-Barmaky, on the authority of Abdullah ibn Dahir, on the authority of Abi Qatadah al-Horani, on the authority of Vaki’a ibn al-Jarah, on the authority of Suleiman ibn Mihran, on the authority of Aba Abdullah as-Sadiq (MGB)
"What the Prophet (MGB) meant when he (MGB) said, ‘statement: ‘I am the son of the two offerings’ was to call one’s uncle father as the Honorable the Exalted God did in His statement,“Were ye witnesses when death appeared before Jacob? Behold, he said to his sons: "What will ye worship after me?" They said, "We shall worship Thy God and the God of thy fathers, of Abraham, Isma’il and Isaac,- the one (True) God: To Him we bow (in Islam).”In this verse God has called Ishmael who was the uncle of Jacob as his father. Likewise, the Prophet (MGB) called uncle as father. Therefore, when the Prophet (MGB) said that he (MGB) is the son of the two offerings he (MGB) is referring to Ishmael and Isaac one of whom, i.e. Ishmael was a true offering and the other one, i.e. Isaac is a virtual offering due to the fact that he wished he had been offered as a sacrifice and deserved the reward. Thus, the statement ‘I am the son of the two offerings’ can be interpreted in both ways as said above.
