Masha Allah great article, but I would like to ask a question on this subject:
If only walima is sunna, then what about all other ceremonies, such as the wedding night (rukhsati in Urdu), that are a part of the custom and have nothing to do with sunna? If it is impermissible to spend extravagantly even in walima, and walima is a sunna, then what about these other function that are not sunna in the first place? Wouldn't it be impermissible to even hold these functions?
Barak Allahu feek.
