The people who claimed to be the Imam in the age of Ali Ibn Husayn (a.

The people who claimed to be the Imam in the age of Ali Ibn Husayn (a.s.) had no true reason for their Imamate and their claims were invalid. Therefore, the Imamate of Ali Ibn Husayn (a.s.) is proved, as there should be an Imam on the earth.

Third, there are some traditions from the Messenger of Allah (S) about the Imamate of Ali Ibn Husayn (a.s.), such as the tradition Jabir has narrated from (S), Imam Muhammad Baqir (a.s.) narrated from his father, from his grandfather, and from Fatimah (s.a.), daughter of the Messenger of Allah (S). The names of the twelve Imams, including Imam Sajjad (a.s.), are recorded in this tradition.

As mentioned in the traditions, Amiral Mu’minin (a.s.) had declared the Imamate of Ali, son of Husayn Ibn Ali (a.s.), when Husayn Ibn Ali (a.s.) was alive. Moreover, Husayn Ibn Ali (a.s.) referred to the Imamate of his son, Ali, in his will before being martyred and gave the will to Umm Salaamh to be given to his son, Ali, after himself.

Imam Husayn (a.s.) has considered asking for the will from Umm Salamah as a sign of the real Imam.[^12] Jabir Ibn Abdullah ‘Ansari told the Prophet (S), “O Messenger of Allah! Who will be the Imams from the progeny of Ali Ibn Abi Talib?” (S) stated, “Hasan and Husayn, masters of youth of the Paradise. Then master of the worshippers, Ali Ibn Husayn and then Baqir; Muhammad Ibn Ali. O Jabir! You will be alive and see him, so say my hello to him!

After him, Sadiq, Ja’far Ibn Muhammad, then Al-Kadhim, Musa Ibn Ja’far, then Ridha’, Ali Ibn Musa. After him, Taqi, Muhammad Ibn Ali, and then Naqi, Ali Ibn Muhammad. After him, Zaki, Hasan Ibn Ali, and then his son, Qa’im, Mahdi. He will fill the world with justice after being filled with injustice and oppression. O Jabir! They will be my successors, progeny, and caliphs. Everyone who obeys them has obeyed me. And everyone who disobeys them has disobeyed me.

Everyone who denies one or all of them has denied me. Allah keeps the earth from swallowing its residents because of the bliss of their existence.”[^13] Virtues of Imam Sajjad Ali Ibn Husayn (a.s.) was the best most virtuous of the people of his own age, so he was called the adornment of the worshippers.
