One recitation is“Aale-Yasin” and the other recitation is“El-Yasin” . The difference in recitation does not imply distortion of the holy Qur’an. Distortion takes place when there is a major change, or additions in the verses by the fabricators. While difference in recitation (that is normally rooted in dialect and accent of various tribes) occurs in less significant cases. The common Sunnis have different ways of recitation with respect to most of the verses.
In the beginning of Ziarat Aale-Yasin we read,“Salaamun-Ala-Aale-Yasin” and we mean Hazrat Mahdi (a.t.f.s.). The proof that Aale-Yasin refers to the holy Prophet’s progeny and in this particular Ziarat to Hazrat Mahdi (a.t.f.s.) is that“Yasin” is a name of the holy Prophet and“Aale-Yasin” are his progeny.
Shias and Sunnis have both narrated that“Yasin” is a name of the holy Prophet.
We shall review the following references:
Ibne-Abbas has narrated that“Yasin” is Muhammad (p.b.u.h) and verbally has said, O Muhammad![101]
Imam Baqir (a.s.) said,“Allah’s messenger has twelve names, that five of them appeared in the Qur’an: Muhammad, Ahmad, Abdullah, Yasin, and Noon” .[102]
In Tafsir (interpretation) of verse 130, chaptor Saffat,[103] it is said that this verse is in honour of Ali (a.s.), and he is from the progeny of“Yasin” , the holy Prophet (s.a.w.a.).
Amir-ul-Mumineen (a.s.) says:
“The Prophet (s.a.w.a.) is “Yasin” and we are“Aale-Yasin” .
Hafiz Hasakani has related from various narrators:
“By Aale-Yasin” is meant“Aale-Muhammad” , and Ali (a.s.) is among“Aale-Muhammad” (progeny of Muhammad).[104]
Thus, it becomes clear that the term“Aale-Yasin” appearing in the traditions refers to the holy Prophet’s progeny.
