Saying Karrama Allaah wajhahu for ‘Ali ibn Abi Taalib
Question

                I know that  Amer almo'meneen Ali Bin abe Taleb rathey allah annah one of the great sahaba and the 4th khalefah to almo'meneeen and did not mada sojob to any image so we called him karram allah wajha .. but my Question is who is the person called Ali Bin Abe Taleb ( eb karram allah wajaha ) ??.
Praise be to Allah.
    It seems that the first ones who said “Karrama Allaah 
    wahjahu” (may Allaah honour his face) concerning ‘Ali ibn Abi Taalib 
    (may Allaah be pleased with him) were the Shi’ah, and some of the scribes 
    who took this from the Shi’ah.  

    1 – Imam Ibn Katheer (may Allaah have mercy on him) said: 

    I say: it is very common among many of the scribes who copy 
    out books to write ‘alayhi’l-salaam (peace be upon him) after the 
    name of ‘Ali (may Allaah be pleased with him) but not after the names of 
    other Sahaabah, or to write karrama Allaah wajhahu. Even though the 
    meaning is acceptable, all the Sahaabah should be treated with the same 
    respect. The two Shaykhs (i.e., Abu Bakr and ‘Umar) and ‘Uthmaan are more 
    deserving of that, may Allaah be pleased with them. 

    Tafseer Ibn Katheer, 3/517-518 

    2 – The Standing Committee said:

     Saying karrama Allaahu wajhahu after the name of ‘Ali 
    and singling him out for that is part of the exaggeration of the Shi’ah 
    concerning him. And it was said that this is because he never saw the ‘awrah 
    of another person, or because he never prostrated to any idol.  

    But this does not apply only to him; it applies also to other 
    Sahaabah who were born in Islam. 

    And Allaah knows best.
