She died during the ‘iddah following divorce; can her husband wash her?
Question

                A woman was divorced by her husband, and during the ‘iddah she died. Is it permissible for her husband to wash her when she was observing ‘iddah?
Praise be to Allah.
    Firstly: 

    In the answer to question no.
    14016, we stated that it is 
    permissible for one of the spouses to wash the other (ghusl in preparation 
    for burial). 

    Secondly: 

    If the wife dies during the ‘iddah following divorce 
    (talaaq), if it was a revocable divorce, it is permissible for the husband 
    to wash her; by the same token, if the husband dies after issuing a 
    revocable divorce, his wife may wash him, because the woman who is revocably 
    divorced still comes under the rulings on wives, so she has the same rights 
    and duties as other wives. 

    Ibn Qudaamah (may Allah have mercy on him) said: If he 
    divorces his wife, then one of them dies during the ‘iddah, if the divorce 
    (talaaq) was revocable, then they come under the same rulings as spouses 
    before divorce, because she is still regarded as a wife and should observe 
    ‘iddah following the husband’s death; and she inherits from him and he 
    inherits from her, and it is permissible for him to have intercourse with 
    her.

    But if the divorce was in return for compensation (as in the 
    case of khula‘) or there had been three divorces (talaaqs), it is not 
    permissible for one of them to wash the other, because the marital 
    relationship has come to an end. 

    Ibn Qudaamah (may Allah have mercy on him) said: If it was a 
    final, irrevocable divorce, It is not permissible, because it is haraam to 
    touch or look (at one another) when still alive, and that applies more 
    emphatically so after death.

    End quote from al-Mughni, 2/201 

    Ibn ‘Abd al-Barr (may Allah have mercy on him) said: They 
    (the scholars) are unanimously agreed that an irrevocably divorced woman 
    cannot wash her husband if he dies during her ‘iddah.

    End quote from al-Istidhkaar, 3/11. 

    An-Nawawi (may Allah have mercy on him) said: They are 
    unanimously agreed that the case of complete or irrevocable divorce, the 
    surviving spouse cannot wash the spouse who has died.

    And Allah knows best.
