The Black Stone’s Testimony for Imam Ali ibn al-Husayn after Karbala

The report begins after the martyrdom of Imam al-Husayn. Al-Kafi says that Muhammad ibn al-Hanafiyya asked Imam Ali ibn al-Husayn for a private meeting and raised the question of who now held the wasiyya and Imamate. In the report, Muhammad refers to his greater age and his closeness as a son of Imam Ali. Ali ibn al-Husayn answers that Imam al-Husayn had appointed him before leaving for Iraq, renewed the covenant shortly before his martyrdom, and that the weapon of the Messenger of Allah ﷺ was in his possession.

Ali ibn al-Husayn then proposes a sign rather than leaving the matter as an argument. The report explicitly locates the conversation in Mecca. They go to the Black Stone, and Ali ibn al-Husayn tells his uncle to begin: pray to Allah, ask Him to make the Stone speak, and then present the question.

Muhammad ibn al-Hanafiyya prays and addresses the Stone, but no answer comes. Ali ibn al-Husayn says that if Muhammad were the appointed successor and Imam, the Stone would have answered him. Muhammad then asks his nephew to pray.

Ali ibn al-Husayn supplicates and addresses the Black Stone by invoking the One who placed within it the covenant of the prophets, the successors and all people. He asks it to declare the successor and Imam after al-Husayn. The report reaches its climax here: the Stone moves so strongly that it nearly leaves its place. Then, according to al-Kafi, Allah causes it to speak in clear Arabic and testify that the wasiyya and Imamate after al-Husayn belong to Ali ibn al-Husayn ibn Ali ibn Abi Talib, descendant of Fatima, daughter of the Messenger of Allah ﷺ.

Al-Kafi closes the scene by saying that Muhammad ibn al-Hanafiyya departed acknowledging Ali ibn al-Husayn as his wali. Al-Majlisi explains this as recognition of his Imamate. The early al-Imamah wa al-Tabsirah preserves the same core account and separately says that Muhammad did not die until he believed in Ali ibn al-Husayn. Al-Tusi later calls the Black Stone story well known among the Imamiyya and preserves a fuller version in which Muhammad first questions how a stone could hear or answer.

Its hadith standing within Twelver Imami scholarship is notably strong for a miracle report. Al-Majlisi grades the first al-Kafi chain sahih and the second hasan like sahih. Sayyid al-Khoei also explicitly calls the report sahih in chain and says it shows Muhammad ibn al-Hanafiyya's acceptance of Ali ibn al-Husayn's Imamate. The proper qualification is that this authentication belongs to Twelver Imami hadith methodology; it should not be turned into a claim of historical consensus among all Islamic schools.
