- “The Mahdi is one of us, the People of the House. Allah will set him aright in a single night.”
It was narrated by Ibn Majah (4075), Ahmad (1/84), al-ʿUqayli in al-Ḍuʿafāʾ (470), Ibn ʿAdi (2/360), and Abu Nuʿaym in al-Ḥilyah (3/177), through Yasin al-ʿIjli, from Ibrahim ibn Muhammad ibn al-Hanafiyyah, from his father, from ʿAli, attributed to the Prophet. He said: “Yasin is not corroborated in this wording, though there are hadiths concerning the Mahdi with sound chains of transmission through routes other than this one.”
I say: On the contrary, he was corroborated by Salim ibn Abi Hafsah. Abu Nuʿaym transmitted it in Akhbar Isfahan (1/170) from him, together with this Yasin—namely, Ibn Shayban. Al-Bukhari said: “His hadiths warrant scrutiny.” Ibn Maʿin said: “There is no harm in him”; and in another report: “Sound.” Abu Zurʿah said: “There is no harm in him.” Al-Hafiz said in Tahdhib al-Tahdhib: “In Sunan Ibn Majah, Yasin occurs without further attribution, so some later hadith scholars supposed him to be Yasin ibn Muʿadh al-Zayyat and consequently declared the hadith weak on his account; but they were mistaken.” He said in al-Taqrib: “There is no harm in him. Those who claimed that he was Ibn Muʿadh al-Zayyat were mistaken.”
I say: The rest of the narrators are trustworthy, so the chain of transmission is good. However, the aforementioned corroboration by Salim ibn Abi Hafsah—who is truthful in hadith—raises the hadith to the rank of authentic. And Allah knows best.
