Imam Sadiq (peace be upon him) Online Seminary Offers Heartfelt Felicitations on Eid al- Mubahilah
There are many verses in the Quran that emphasize the great station of the Ahl al-Bayt (peace be upon them) yet one verse stands out i.e the verse of Mubahalah.

The great Christian scholars of Najran met the Holy Prophet (peace be upon him and his holy progeny) and had discussions arguing the validity of their religious claims. While disputing upon the core issues of beliefs, it was decided that a divine imprecation (mubahalah) would be called upon for the one who is lying in his claim.  Regarding this, the Quran mentions, "Tell those who dispute this with you even after the knowledge that has reached you: "Come, let us gather our sons and your sons, our women and your women, ourselves and yourselves, and pray and solicit God to condemn those who lie."(3:61)
☀️ On the decided day, when the Christian scholars saw the luminous faces of the Holy Prophet, with his daughter, Lady Fatima, his cousin and his son in law, Imam Ali, and their two children Imams Hasan and Husain (peace be upon them) coming for the Mubahala, they immediately refrained from imprecation and instead offered tribute in return for protection. The Prophet agreed and Islam triumphed on Christianity.

Muslims need to notice that if there was anyone better than those brought by the Prophet, then he would have done so, but, by bringing the Ahl al-Bayt, the prophet laid the foundations for all generations to know the worthiest people on earth and to follow their footsteps to achieve proximity to Allah and prosperity in both worlds.
On this magnificent day, we ask Allah to illuminate our hearts with the knowledge, love, and insight of the Ahl al-Bayt so that we are amongst the supporters of our living Imam, al- Mahdi (may Allah hasten his reappearance)

Imam Ridha (peace be upon him) says: The virtue of Mubahala is so apparent that no one can deny it, not even an enemy.
