Question

                Recently I had some conversation of virtue and culture on wedding night, I just wanted to get clear picture about wedding night, in our country back in India , when groom want to enter the room of bride on first night of wedding relatives and friends dont allow to enter the bedroom of bride and instead they start wasooli(demanding money or for a trip) if groom doesn't agree they not allow to enter , it's just for fun we do, but I heard it's haram , but question is how it is haram when there is nothing against Islam or sharia, please clarify to me as it will help us o correct ourself if we are wrong , also please be noted we will not keep groom and bribe wait for whole night, it's just for fun as we get only one day to celebrate like this, please help us with authentic source from Quran and hadeet.
Praise be to Allah.
    Firstly: 

    Celebrating weddings and other 
    worldly occasions is permissible subject to the condition that they are free 
    of reprehensible matters such as free mixing, music and so on. Such 
    activities are coming under the heading of permissible fun and there is 
    nothing wrong with that according to Islamic teachings. 

    See also the answer to question 
    no. 115148. 

    Secondly: 

    It is not appropriate to stay in 
    a Muslim’s house so long that it causes a disturbance to him or his family. 
    It is also not appropriate to enter his house at a time when he may not like 
    anyone to enter, even if that is by way of joking or having fun. 

    Al-Bukhaari (5163) and Muslim 
    (1428) narrated that Anas ibn Maalik said: The Messenger of Allah (blessings 
    and peace of Allah be upon him) got married and consummated the marriage 
    with his wife. My mother Umm Sulaym made some hays and put it in a 
    stone vessel, then she said: O Anas, take this to the Messenger of Allah 
    (blessings and peace of Allah be upon him). Then he said: “Go and invite So 
    and so for me, and whomever you meet,” and he mentioned some men by name. I 
    invited those whom he had named and whoever else I met. And the Messenger of 
    Allah (blessings and peace of Allah be upon him) said to me: “O Anas, bring 
    the stone vessel.” They came in until they filled the courtyard and the 
    apartment. The Messenger of Allah (blessings and peace of Allah be upon him) 
    said: “Let them make circles of ten, and let each man eat from what is 
    nearest to him.”
    They ate until they were full; one group went out and another group came 
    in, until they had all eaten. Then he said to me: “O Anas, clear it away.” I 
    picked it up, and I do not know whether it held more when I put it down or 
    when I picked it up. Some of them sat talking in the house of the Messenger 
    of Allah (blessings and peace of Allah be upon him), and the Messenger of 
    Allah (blessings and peace of Allah be upon him) was sitting there, and his 
    wife had her face turned towards the wall. They were bothering the Messenger 
    of Allah (blessings and peace of Allah be upon him), so the Messenger of 
    Allah (blessings and peace of Allah be upon him) went out and greeted his 
    wives, then he came back. When they saw that the Messenger of Allah 
    (blessings and peace of Allah be upon him) had come back, they realized that 
    they were bothering him. So they all rushed to the door and left. The 
    Messenger of Allah (blessings and peace of Allah be upon him) came and hung 
    up a curtain and went in, and I was sitting in the apartment. It was not 
    long before he came out to me, and this verse had been revealed. The 
    Messenger of Allah (blessings and peace of Allah be upon him) went out and 
    recited it to the people: 

    “O you who believe! Enter not 
    the Prophet’s houses, unless permission is given to you for a meal, (and 
    then) not (so early as) to wait for its preparation. But when you are 
    invited, enter, and when you have taken your meal, disperse without sitting 
    for a talk. Verily, such (behaviour) annoys the Prophet…”

    [al-Ahzaab 33:53]. 

    Al-Haafiz Ibn Hajar (may Allah 
    have mercy on him) said: 

    What is meant by dispersing 
    after having eaten is moving from the place where people ate so as to make 
    it easier for the owner of the house. End quote. 

    Ibn Battaal (may Allah have 
    mercy on him) said: 

    Causing annoyance to the Prophet 
    (blessings and peace of Allah be upon him) is haraam for all of his ummah. 
    Similarly, it is haraam for the believers to cause annoyance to one 
    another. 

    From the hadeeth we learn the 
    fiqhi ruling that if a person sits for so long in someone else’s house that 
    he causes annorance to the owner of the house, it is permissible for the 
    owner to get up and leave him, or to tell him that he needs him to leave, so 
    that he will leave, and that is not bad manners.

    End quote from Sharh Saheeh 
    al-Bukhaari (9/510). 

    A Muslim may be annoyed by 
    something that his friends do to him by way of joking and playing, or by way 
    of following the people’s customs, but he may feel too shy to tell them not 
    to do that, for fear of hurting their feelings. The wise Muslim would not do 
    that to his Muslim brother, especially in his house and on his wedding 
    night. He may be upset by that, but feel too shy to say anything to them, 
    and his wife may be upset and annoyed by that deed. With regard to such 
    matters, the least that may be said is that they are makrooh (disliked), if 
    they cause any harm or annoyance to the groom or to the owner of the house. 

    What should be done is to adhere 
    to the Islamic etiquette having to do with asking permission to enter, 
    entering the house and staying in the house, especially at sensitive times 
    when staying for too long may cause a great deal of inconvenience to the 
    household. 

    Moreover, asking the groom for 
    money or anything else that may impose a burden on him – even by way of 
    joking, may embarrass him and make him respond to this request, so he may 
    use some of his money to pay his friends unwillingly. Ahmad (20577) narrated 
    from ‘Amr ibn Yathribi that the Messenger of Allah (blessings and peace of 
    Allah be upon him) said: “It is not permissible for a man to take any of his 
    brother’s wealth unless he gives it willingly.” Classed as saheeh by al-Albaani 
    in al-Irwa’ (2/279) 

    Al-Qaari (may Allah have mercy 
    on him) said:

    It is haraam to take anything by 
    means of shyness. 

    End quote from Mirqaat al-Mafaateeh 
    (4/1330) 

    To sum up: 

    This action should be avoided 
    and this tradition should be abandoned, because of what it may lead to of 
    embarrassment, distress and annoyance, whether to the man or his bride. 

    You can visit at some other 
    time, and you can joke in some other way. 

    A man said to Sufyaan ibn 
    ‘Uyaynah (may Allah have mercy on him): Joking is objectionable. He replied: 
    Rather it is Sunnah, but only for the one who does it in an appropriate 
    manner at an appropriate time.
