It is permissible for the husband to receive well-wishers when he is junub
Question

                People in our country visit the bride and bride groom at the wedding night to congratulate them and sit with them for some time, women with the bride, and men with the groom. Thus they meet the guests before ghusl (bath) of janaba (impurity after an intercourse). Is this permissible? Or should they firstly have ghusl then receive the guests? This will take them a long time to get ready, specially the bride. What is the opinion on this?.
Praise be to Allah.
    There is nothing wrong with one who is junub coming to 
    receive well-wishers and to greet them and sit with them, because of the 
    report narrated by al-Bukhaari (238) and Muslim (372) from Abu Hurayrah, 
    that he met the Prophet  (peace and blessings of Allaah be upon him) in 
    one of the streets of Madeenah when he was junub. He slipped away and went 
    to do ghusl, and the Prophet (S) noticed he was gone. When he came to him, 
    he said: “Where were you, O Abu Hurayrah?” He said: O Messenger of Allaah, 
    you met me when I was junub, and I did not like to sit with you until I had 
    done ghusl. The Messenger of Allaah (S) said: “Subhaan-Allaah, the believer 
    does not become naajis.” 

    But it is better for him to do wudoo’, because of the report 
    narrated by Muslim (305) from ‘Aaishah who said: When the Messenger of 
    Allaah (S) was junub and wanted to eat or sleep, he would do wudoo’ as for 
    prayer. 

    And because the angels do not come close to one who is junub, 
    as it says in the hadeeth from the Prophet  (peace and blessings of 
    Allaah be upon him): “There are three whom the angels do not approach: the 
    dead body of a kaafir, the one who is perfumed with khalooq and the one who 
    is junub, until he does wudoo’.” Narrated by Abu Dawood (4180); classed as 
    hasan by al-Albaani in Saheeh Abi Dawood (3522). 

    “The one who is perfumed with khalooq” refers to a man who is 
    wearing perfume containing saffron, because that involves frivolity and 
    imitation of women. Fayd al-Qadeer (3/325).

    As for these bad customs, people should be made aware and warned against 
    them, because such gatherings are embarrassing for the newly-weds, and may 
    cause them psychological distress that they do not need in these 
    circumstances, i.e., when the man and his wife feel that his relatives and 
    friends are waiting for them to finish what they are doing, so that they can 
    congratulate them after that! 

    The time for offering congratulations is not limited to this 
    embarrassing time. These congratulations can be offered during the wedding, 
    or after that night, or at any other time. There is no point in singling out 
    that time for congratulating the couple, apart from ancient foolish customs 
    that have no basis in sharee’ah and serve no purpose according to common 
    sense, and are not good manners. 

    And Allaah knows best.
