GRAVITY WAVES DETECTED - afterglow of the BIG BANG

Re: GRAVITY WAVES DETECTED - afterglow of the BIG BANG

its a book written by an Aalim in late 1800’s I think, precisely for the new brides of Then indo pak. The book was so famous that it became an almost certain part of every muslim bride’s dowry. Its a book that talks about Islamic mannerisms and rulings related to marriages.

PS: Muzna hates that book, hence me pulling her leg in this thread.
