The following translation is of a response by a contemporary Zaydi scholar, Allama Abdullah ash-Shâdhili, may Allah have mercy on him:
As for the return of Christ, upon him be peace, I am not aware of the statements of our imams, upon them be peace, concerning this issue—by that, I mean the early authorities (al-mutaqadimîn). This is because the issue is not one of affirming deviance or related to the belief or practice. There has not been any from our imams who has refuted or established it.
What is clear to me is that those narrations that have infiltrated are amongst the narrated Jewish legends (Isrâ`îlîyât), especially from the books of the Jews and their interpolations. This is because they do not recognize the Christ that was sent before the Prophet, peace and blessings be upon him and his progeny, and they are still waiting for his coming. Yet, according to the Christians and Muslims, he has already been sent. Therefore, they constructed these narrations of his return. The issue is one of small advantage because the one who says that he is to return makes the return under the rule of the Muslims and under the leadership of the Mahdi.
