Khalifatul-Masih V (may Allah be his Helper) has sent the following instructions
In the Jama'at, the trend to spend extravagantly and follow rasms (innovations/rituals) has begun again. Some rituals have been adopted in Pakistani and Indian cultures, which have nothing to do with the teaching of Islam. An impression has been created regarding these rituals that they are perhaps part of necessary obligations of marriage. It is assumed that the marriage cannot take place without them, and much is spent extravagantly for this purpose.
The ritual of mehndi is being given the same importance as marriage. An invitation is sent out for mehndi, cards are printed, stages are decorated, and on top of that, the process of these invitations extends over a long period. It is initiated even some time before marriage. In some cases, it begins many weeks before marriage and, every day, a new stage is decorated, and then there is discussion that such and such food was prepared this day and such food was prepared the next day. These are all innovations which have been adopted even by those who cannot afford them. Such people who cannot afford them practise the rituals anyways and go into debt. Ahmadis should consider these matters specially. We should refrain from spending extravagantly for mehndi or having a large party and food.
The Promised Messiahas once said, "A bad innovation among our people is that people spend thousands on marriages". A hundred years ago, or even before that, spending thousands was considered extravagant. However, nowadays, instead of thousands, hundreds of thousands are spent and this spending is much greater than affordability.
I am receiving some complaints that some people have indulged in these rituals too much. That is why I am saying it openly not to follow these abhorrent rituals and innovations, and this should stop. It should not be that marriages are used for extravagant spending or show-off, or to display one's status and wealth.
Every Ahmadi should understand his position that Allah, the Exalted, has graciously enabled him to be a member of the Jamaat of the Promised Messiahas. Now, it is his responsibility to follow the correct Islamic teaching.
Some women say, "If women dance while in the presence of other women, how does it matter?" It does matter even if women are dancing among other women. The Holy Quran has stated that this spreads immorality. Hence, every Ahmadi woman should follow this commandment. In the same way, too much is spent on invitation cards for marriage.
Every Ahmadi should keep away from such vain pursuits. In order to become true members of the Jama'at of the Promised Messiah", it is necessary to keep away from every such thing which is harmful and an innovation in religion.
