Classical sources preserve reports that al-Ala ibn al-Hadrami may Allah be pleased with him died during travel and was buried by his companions. The companions are then said to have returned to the burial place, after which the grave or body could no longer be found. Ibn Sa'd preserves an early biographical form, while al-Tabarani, Abu Nu'aym, and al-Lalaka'i preserve related versions. Every checked route for the extraordinary disappearance has material weakness, and the sources differ over why the companions returned to the grave, so the event remains a low-confidence reported karamah requiring editorial review.
The extraordinary element comes when the companions return. The reports say that al-Ala's body was no longer found, or that they could no longer see or locate him in the grave. Ibn Sa'd preserves an early biographical form from al-Sha'bi in which al-Ala dies near a place identified as Biyas or Balyas and, after burial, the companions return and cannot find the grave location. Al-Tabarani and Abu Nu'aym preserve an Abu Hurayra route in which he is buried in sand and the companions later return but do not see him in the grave. Al-Lalaka'i includes the missing-body episode at the end of his fuller karamah narrative of al-Ala.
The classical preservation is real, but the transmission problems are also substantial. Ibn Sa'd's route passes through Mujalid ibn Sa'id, who is weak in hadith and suffered from poor memory and ikhtilat, while al-Sha'bi's report is historical rather than a direct eyewitness chain. The Abu Hurayra route contains Ibrahim ibn Ma'mar al-Harawi, whom al-Haythami says he did not know, although the remaining men were trustworthy. Al-Lalaka'i's fuller route contains Adi ibn al-Fadl, whom the critics judged matruk.
These sources therefore establish the existence and classical reception of the story more securely than they establish the extraordinary disappearance itself as historical certainty. The safest public account is that Sunni classical literature preserves a report that al-Ala was buried and that his companions later returned but did not find his body or could no longer locate the grave. Because every checked extraordinary-outcome route has a material defect, the event should remain a low-confidence reported karamah and an editorial working draft rather than an authenticated fact.
Conclusion
Classical Sunni sources preserve a report that al-Ala ibn al-Hadrami was buried and that his companions later returned but did not find his body or could no longer locate the grave. Because the extraordinary outcome is transmitted only through materially weak routes, it should remain a low-confidence reported karamah requiring editorial review.
