The name of the wife of Ayyoob (peace be upon him)

The historians and some of the mufassireen
have stated that her name was Rahmah bint Meesha ibn Yoosuf ibn Ya’qoob. 

But this is something which is not proven
in any clear sound text, rather it was transmitted from the books of
the People of the Book, or by some Muslims from them. We shall list
those who were of this view and transmitted it: 

1 – Al-Suyooti said: Ibn ‘Asaakir narrated that Wahb
ibn Munabbih (may Allaah be pleased with him) said: “The wife of Ayyoob
(peace be upon him) was Rahmah (may Allaah be pleased with her) bint
Meeshaa ibn Yoosuf ibn Ya’qoob ibn Ishaaq ibn Ibraaheem (peace be upon
them).

(al-Durr al-Manthoor, 7/197. Also
in Tafseer al-Baydaawi, 3/310; Tafseer al-Qurtubi,
9/265; Tafseer al-Baghawi, 2/451) 

2 – Shaykh al-Islam Ibn Taymiyah (may
Allaah have mercy on him) said:

But these Israa’eeli (i.e., Jewish) reports
to be mentioned for the purpose of proving a point, they are not to
be believed. They are of three types:

(i)Those which we know are
sound because of evidence which we have which proves them to be true.
These are saheeh.

(ii)Those which we know are
false because of evidence which we have which contradicts them.

(iii)Those which we do not know
whether they are true or false. So we do not believe in them and we
do not disbelieve in them, but it is permissible to narrate them for
the reasons given above. 

Most of them are things which serve no
religious purpose, hence the scholars of the People of the Book differ
greatly concerning such things. The mufassireen also differed concerning
them as a result of that, as they mentioned, for example, the names
of the People of the Cave, the colour of their dog and their number,
or what kind of tree the staff of Moosa came from, and other matters
which Allaah did not mention in detail in the Qur’aan because knowing
the specific details does not serve any worldly or religious purpose. 

(Majmoo’ al-Fataawa, 13/366-367). 

Al-Shanqeeti (may Allaah have mercy on
him) said:

 What the mufassireen have said
concerning the name of their dog – some said that its name was Qitmeer,
and some said that its name was Hamdaan, etc. – we need not dwell on
at length, because it serves no purpose. There are many things in the
Qur’aan which neither Allaah nor His Messenger has explained to us in
detail, and there are no proven reports concerning them; there is no
benefit to be gained by researching such matters. 

(Adwaa’ al-Bayaan, 4/48) 

And Allaah knows best.
