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

                What is the name of the wife of Ayyoob (peace be upon him)?
Praise be to Allah. 
          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.
