shrine in Ascalon had been established after 490 AH.
Thus, this Cairene shrine has its origin in that shrine in Ascalon. The shrine in Ascalon was established more than 430 years after al-Husayn’s killing, and the Cairene shrine nearly 500 years after his killing. There has been no disagreement about this among the various scholars who have addressed this subject, including hadith scholars, compilers of accounts of Cairo, and historians. Scholars have transmitted this from generation to generation, and such matters are widely known among them.
This is well known among them and established by mass transmission, regardless of whether the shrine’s attribution to al-Husayn is considered true or false. They have not disputed that it was transferred from Ascalon during the final years of the Ubaydī dynasty.
Since this Cairene shrine derives from the shrine in Ascalon, as is universally agreed and established by mass transmission, it is clear that the claim that the shrine in Ascalon was built over the head of al-Husayn, may Allah be pleased with him, has no evidence whatsoever. None of the scholars whose concern it is to transmit such accounts has reported this: neither hadith scholars, nor scholars of historical accounts and chronicles, nor scholars who have written on genealogy—the genealogy of Quraysh, Banū Hāshim, and the like.
