قال: أليس عيسى من ذرية إبراهيم وليس له أب؟ قال: صدقت.
قال: أليس عيسى من ذرية إبراهيم وليس له أب؟ قال: صدقت." One day, Hajjaj (ibn Yusuf) ordered that Yahya ibn Ya‘mur should be brought and when he saw him he said to him: “I have been told that you opine that al-Hasan and al-Husayn are the children and offspring of the Prophet (S) and you say that you have found this in the Book of Allah whereas I have read the Qur’an from the beginning to the end but I have not found such a thing.” Yahya asked: “Have you not read this verse in Surah al-An‘am : ‘ and from his (Abraham’s) offspring, David and Solomon ’ and continued up to, ‘and John and Jesus’ ?” He replied: “Yes, I have.” Yahya asked: “In this Qur’anic verse, has Jesus not been considered among the offspring of Abraham eventhough Abraham was not his father {and Jesus can be traced back to Abraham through his mother (Mary)}?” Hajjaj said: “You are correct.”[^2] From the aggregate of the quoted verses and the words of Qur’an exegetes, it becomes obvious that not only the Shi‘ah but in fact all Muslim scholars regard Imam al-Hasan and Imam al-Husayn ( ‘a ) as the children and offspring of the Messenger of Allah (S).
Let us call our sons and your sons, our women and your women, our selves and your selves, then let us pray earnestly and call down Allah’s curse upon the liars’.” [^3] Exegetes say: The stated verse which is known as the verse of mubahilah tells about the debate of the Holy Prophet (S) with the chiefs of the Christians of Najran after their expression of obstinacy.
By a Divine command, the Prophet went out along with ‘Ali ibn Abi Talib, Fatimah az-Zahra, and Imam al-Hasan and Imam al-Husayn ( ‘a ) with the aim of imprecation. When the chiefs of the Christians noticed the behavior of the Prophet and the ( ‘a ), fear struck in their hearts and they asked the Messenger of Allah (S) to reconsider his decision to imprecate and curse them.
